Cluster headaches are characterized by severe, unilateral, sharp, or stabbing pain typically centered in or around one eye. They often occur in clusters over several days or weeks at the same time each day. Ipsilateral autonomic symptoms such as lacrimation, ptosis, and nasal congestion are classic findings. These headaches usually last 15 minutes to 3 hours and can be extremely disabling during an episode.

Rationale for correct answer:
2. Cluster headache: The presentation of sharp unilateral periorbital pain with ipsilateral tearing and ptosis, recurring daily at the same time, is classic for cluster headaches. The pattern and autonomic symptoms help confirm the diagnosis.

Rationale for incorrect answers:

1. Tension-type headache: Usually bilateral, with a dull, band-like pressure. No autonomic symptoms or predictable timing.

3. Migraine headache with aura: Often preceded by visual disturbances or sensory changes, usually throbbing rather than sharp, and associated with photophobia and nausea—not primarily tearing or eyelid droop.

4. Medication overuse headache: Caused by frequent analgesic use, typically presents as a diffuse, daily headache without autonomic symptoms or predictable timing.

Take home points

• Cluster headaches are intense, short-lived, and recur in predictable cycles.
• Autonomic features such as lacrimation, ptosis, and nasal congestion are key diagnostic clues.
• Differentiation from migraines and tension headaches is based on timing, quality, and associated symptoms.

Tension-type headaches are the most common primary headache disorder. They typically present as bilateral, pressing, or tightening pain that feels like a tight band around the head. Chronic forms may last for hours or days and can be associated with muscle tenderness in the neck and shoulders. They are not usually triggered by specific foods, and photophobia or phonophobia is rare or mild if present.

Rationale for correct answers:

1. Constant, band-like pressure: This is the hallmark description of tension-type headaches.

3. Muscle tenderness: Increased pericranial muscle sensitivity, especially in the neck and shoulders, is common.

5. Duration: Can last from 30 minutes to several days, especially in the chronic form.

Rationale for incorrect answers:
2. Unilateral and throbbing: More characteristic of migraine headaches, not tension-type headaches.
4. Dietary triggers like aged cheese: These are commonly associated with migraines, not tension-type headaches.
6. Photophobia and phonophobia: While they may occur mildly in some cases, they are not defining features and are more strongly linked to migraines.

Take home points

• Tension-type headaches are usually bilateral, pressing, and non-pulsating.
• They are often linked to stress, fatigue, and poor posture, not dietary triggers.
• Muscle tightness in the neck and scalp is a key finding.

Migraines are often accompanied by sensory hypersensitivity such as photophobia and phonophobia, as well as gastrointestinal symptoms like nausea and vomiting. The priority in acute migraine care is to reduce sensory stimulation and promote comfort. Dimming the lights and providing a quiet environment can help minimize triggers and allow the client to rest while additional treatments (like medications) are prepared.

Rationale for correct answer:
2. Dim the lights and provide a quiet environment: This immediately reduces environmental stimuli, which can lessen headache intensity and discomfort. It addresses the client’s acute sensory sensitivity and supports recovery.

Rationale for incorrect answers:

1. Administer a prescribed oral analgesic: While pain medication is important, severe nausea/vomiting may make oral administration ineffective; environmental control should come first.

3. Offer a high-carbohydrate snack: Food is not a priority in acute migraine management and may worsen nausea/vomiting.

4. Encourage ambulation: Movement often worsens migraine symptoms; rest is preferred during acute attacks.

Take home points

• First action in acute migraine care is reducing sensory stimuli.
• Oral medications may be ineffective if severe nausea is present—consider alternative routes.
• Rest in a dark, quiet environment can significantly ease symptoms before further interventions.

This presentation is classic for a migraine headache with aura. The aura phase may include visual changes (shimmering lights, zigzag lines, blind spots) that precede the headache. Migraines are typically unilateral, throbbing, and associated with nausea, vomiting, photophobia, and phonophobia.

Rationale for correct answer:
3. Migraine headache: Auras occur in about 25% of migraine cases and are neurological symptoms that precede or accompany the headache. They often involve visual disturbances, sensory changes, or speech difficulties.

Rationale for incorrect answers:

1. Cluster headache: Produces severe unilateral orbital pain with autonomic symptoms (lacrimation, nasal congestion, ptosis) but no visual aura.

2. Sinus headache: Usually associated with facial pain/pressure, nasal congestion, and worsens with bending forward, not with visual changes.

4. Rebound headache: Results from overuse of headache medications; symptoms are diffuse, often daily, without aura.

Take home points

• Migraines with aura often involve visual disturbances before headache onset.
• Unilateral, throbbing pain plus nausea is highly suggestive of migraine.
• Cluster headaches are severe but do not typically include a visual aura.

A tension-type headache is the most common primary headache disorder. It is often described as a dull, aching, or band-like pressure around the head, linked to stress, fatigue, or poor posture. Unlike migraines, tension-type headaches do not usually cause nausea, vomiting, photophobia, or phonophobia.

Rationale for correct answer:
3. Tension-type headache: Characterized by bilateral, non-throbbing pain often described as a “tight band” or “vice-like” pressure. Commonly linked to stress or muscle tension and generally free from nausea or sensory hypersensitivity.

Rationale for incorrect answers:

1. Migraine headache: Usually unilateral, throbbing, often accompanied by nausea, vomiting, and sensitivity to light and sound.

2. Cluster headache: Severe unilateral orbital pain with autonomic features (tearing, nasal congestion, ptosis), not a “band-like” pressure.

4. Sinus headache: Associated with nasal congestion, facial pain, and worsens when bending forward.

Take home points

• Tension-type headaches are bilateral, band-like, and pressure-type without neurological symptoms.
• Triggered by stress, fatigue, and poor posture.
• Do not involve photophobia, phonophobia, or nausea in most cases.

Chronic tension-type headaches are often associated with muscle tension, stress, and poor posture. Non-pharmacological interventions aim to reduce muscle tightness and stress, and improve coping strategies. Evidence-based approaches such as acupuncture, relaxation training, and biofeedback have been shown to help reduce headache frequency and severity.

Rationale for correct answers:

1. Acupuncture: Stimulates specific points in the body to help reduce headache frequency and intensity; may benefit some clients with tension-type headaches.
2. Relaxation training: Techniques like progressive muscle relaxation and deep breathing reduce stress and muscle tension, helping prevent headache onset.
3. Biofeedback: Teaches clients to monitor and control muscle tension and other physiological processes to reduce headache occurrence.

Rationale for incorrect answers:
4. Feverfew supplements: Primarily used for migraine prevention; limited evidence supports its use for tension-type headaches.
5. Botox injections: Approved for chronic migraine prevention, not indicated for tension-type headaches.

Take home points

• Stress management strategies are a cornerstone of tension-type headache treatment.
• Acupuncture, relaxation training, and biofeedback are safe and effective non-drug interventions.
• Supplements and Botox are better suited for other headache types, particularly migraines.

Sumatriptan is used for the acute treatment of migraine attacks and is most effective when taken at the first sign of symptoms. It is not for daily preventive use and should not be taken with serotonergic supplements like St. John’s Wort. The tablet form should be swallowed whole unless otherwise directed by the manufacturer.

Rationale for correct answer:
2. "This medication should be taken at the first sign of a migraine headache.": Early administration increases its ability to stop the migraine before it becomes severe.

Rationale for incorrect answers:

1. "You should take this medication daily to prevent headaches from occurring.": Daily use is not recommended; it increases the risk of rebound headaches.

3. "This medication can be safely used with St. John's Wort to enhance its effects.": This combination increases the risk of serotonin syndrome, which can be life-threatening.

4. "You may crush or chew the tablet for faster absorption if the headache is severe.": Crushing or chewing may alter absorption and effectiveness; the tablet should be swallowed whole.

Take home points

• Sumatriptan is for acute migraine relief, not prevention.
• Take it at the first sign of a migraine for best results.
• Avoid combining with serotonergic substances like St. John’s Wort.
• Swallow the tablet whole unless your healthcare provider gives different instructions.

High-flow oxygen therapy via a non-rebreather mask at 12–15 L/min is the first-line treatment for acute cluster headaches. The client should sit upright during administration, and therapy typically continues for about 10–20 minutes or until symptoms resolve.

Rationale for correct answer:
3. "You should use a non-rebreather mask and sit upright during a headache attack.": This ensures high oxygen concentration delivery and optimal breathing mechanics to relieve pain quickly.

Rationale for incorrect answers:

1. "The oxygen should be delivered at a low flow rate of 2 L/min.": This is insufficient for cluster headache relief; high flow is required.

2. "You should use a nasal cannula for delivery of the oxygen.": A nasal cannula cannot deliver the necessary high concentration of oxygen.

4. "Treatment should continue for at least 60 minutes, even if symptoms subside.": Extended therapy is unnecessary and may cause oxygen toxicity; therapy usually lasts 10–20 minutes.

Take home points

• Use 12–15 L/min oxygen via a non-rebreather mask for acute cluster headaches.
• Sit upright during treatment for optimal relief.
• Therapy generally lasts 10–20 minutes, stopping once symptoms resolve.

Preventive therapy for frequent migraines focuses on medications that reduce the frequency, severity, and duration of attacks. Common classes include beta-adrenergic blockers (e.g., propranolol), certain antidepressants (e.g., amitriptyline), and calcium channel blockers (e.g., verapamil). These work through mechanisms such as stabilizing vascular tone, modulating neurotransmitter levels, and reducing cortical excitability.

Rationale for correct answers:

1. Beta-adrenergic blockers: Effective in migraine prophylaxis by reducing vascular reactivity and stabilizing sympathetic tone.

2. Antidepressants: Tricyclic antidepressants like amitriptyline can reduce migraine frequency, especially when tension-type headaches or depression coexist.

4. Calcium channel blockers: Reduce migraine frequency by preventing abnormal vascular constriction and stabilizing neuronal excitability.

Rationale for incorrect answers:
3. NSAIDs: Primarily used for acute migraine relief, not long-term prevention.
5. Triptans: Designed for acute migraine attacks; not used for daily prophylaxis due to cardiovascular risks.
6. Opioids: Not recommended for migraines due to dependency risks and lack of preventive efficacy.

Take home points

• Migraine prevention commonly involves beta-blockers, certain antidepressants, and calcium channel blockers.
• Acute treatments (e.g., NSAIDs, triptans, opioids) are not used for long-term prophylaxis.
• Preventive therapy is considered for clients with frequent or severe migraine attacks affecting quality of life.

Metoclopramide (Reglan) is often used in the emergency department for acute migraine attacks, particularly when accompanied by nausea and vomiting. It helps relieve gastrointestinal symptoms and can enhance the absorption of co-administered analgesics. It may also have direct anti-migraine benefits due to dopamine receptor antagonism.

Rationale for correct answer:
4. Metoclopramide (Reglan): Effective for acute migraine management, especially when nausea or vomiting limits oral medication absorption. Often given IV along with other acute migraine treatments such as NSAIDs or triptans.

Rationale for incorrect answers:

1. Divalproex sodium (Depakote): Used for migraine prophylaxis, not acute attacks.
2. Topiramate (Topamax): An anticonvulsant used for migraine prevention, not for immediate symptom relief.
3. Propranolol (Inderal): A beta-blocker for migraine prophylaxis, not acute treatment.

Take home points

• Acute migraine therapy targets immediate symptom relief and often combines antiemetics with analgesics or triptans.
• Preventive medications (Depakote, Topamax, propranolol) are not effective for aborting ongoing attacks.
• IV metoclopramide can be a first-line choice in the ED, especially with significant nausea or vomiting.

Frequent migraine headaches are characterized by recurring episodes of moderate to severe pain often associated with triggers and neurological symptoms. In the acute phase, the primary nursing priority is to address the pain experienced by the client. "Acute pain related to biological and physical agents" most accurately reflects the client’s current priority problem.

Rationale for correct answer:
2. Acute pain related to biological and physical agents: Migraines are a result of neurovascular and biochemical changes in the brain that cause intense head pain. Managing pain is the primary focus during and between episodes.

Rationale for incorrect answers:

1. Ineffective coping: May be relevant for chronic illness but is not the immediate priority in acute migraine care.

3. Deficient knowledge: Important for long-term management but does not address the urgent need for pain relief.

4. Risk for injury: Applicable if the client has severe aura symptoms, but pain control remains the more pressing nursing diagnosis.

Take home points

• Acute pain is often the priority nursing diagnosis for clients experiencing migraine episodes.
• Long-term care plans may also address coping strategies, trigger avoidance, and injury prevention.
• Nursing diagnoses should be prioritized according to Maslow’s hierarchy and the immediacy of the problem.

Tension-type headaches are often caused by muscle tension, stress, and poor posture, and they present as bilateral, band-like pressure without severe neurological symptoms. Non-pharmacological interventions, lifestyle modifications, and simple analgesics are the mainstay of management. Patient education focuses on trigger identification, stress reduction, and self-care strategies.

Rationale for correct answers:

1. Headache diary: Helps identify triggers such as stress, sleep deprivation, or dietary factors, enabling effective prevention strategies.

3. Relaxation techniques: Methods like deep breathing, meditation, and progressive muscle relaxation can reduce muscle tension and stress, lowering headache frequency.

4. Regular physical activity: Improves blood circulation, reduces muscle tension, and decreases stress levels, all of which help prevent headaches.

5. Cool cloth application: Provides symptomatic relief during an episode by reducing muscle tightness and providing comfort.

Rationale for incorrect answers:
2. Migraine-specific medications (triptans): These are not first-line treatments for tension-type headaches; they are used for acute migraine attacks. Tension headaches are usually managed with over-the-counter analgesics and non-drug measures.

Take home points

• Tension-type headaches respond best to lifestyle modification and stress management.
• Triptans are not appropriate for this type of headache.
• Prevention focuses on trigger awareness, relaxation, and healthy habits.

Cluster headaches often occur at night, waking the client from sleep with intense, excruciating unilateral pain. The pain is frequently accompanied by agitation or restlessness, as patients tend to pace or rock to cope. The recurring nocturnal nature of attacks significantly disrupts normal sleep patterns, making Disturbed Sleep Pattern an appropriate priority nursing diagnosis.

Rationale for correct answer:
2. Disturbed Sleep Pattern related to nocturnal headache episodes: Cluster headaches commonly begin 1–2 hours after falling asleep during REM sleep. The intense pain forces awakening, leading to chronic sleep disruption. Addressing this problem can improve quality of life and help reduce headache triggers linked to poor sleep.

Rationale for incorrect answers:

1. Chronic Pain: While pain is a primary symptom, cluster headaches are episodic and occur in cycles; the priority diagnosis during active bouts is managing their functional impact, such as sleep disruption.

3. Ineffective Health Maintenance: This may apply if the client cannot follow the treatment plan, but the scenario highlights nighttime disruption, not self-care difficulties.

4. Social Isolation: Some clients may withdraw due to unpredictability of attacks, but this is not the most immediate concern described in this scenario.

Take home points

• Cluster headaches often occur in predictable cycles and are worse at night.
• Sleep disruption is a major consequence that can exacerbate headaches.
• Nursing care should focus on pain relief and restoration of sleep quality.

Medication overuse headaches occur when acute headache medications are used too frequently, leading to a cycle of rebound headaches and increased headache frequency. Taking more of the acute medication in response to worsening headaches only perpetuates the problem. Clients need to understand that reducing or discontinuing the overused medication is necessary, even though symptoms may temporarily worsen during withdrawal.

Rationale for correct answer:
3. "If my daily headache pain increases, I should take more of my acute headache medication to stop it." – This statement reflects a misunderstanding. Increasing medication use worsens MOH by reinforcing the rebound cycle. Education should emphasize prevention through limited use and alternative strategies for headache relief.

Rationale for incorrect answers:

1. Limiting OTC use to no more than two times a week is correct and aligns with prevention guidelines.

2. Acknowledging that MOH can come from prescription or OTC medications is accurate; triptans, opioids, NSAIDs, and combination analgesics are all potential culprits.

4. Stopping the overused medication is indeed the first and most important step in managing MOH.

Take home points

• MOH is most often caused by frequent use of acute migraine or headache medications.
• Limiting use to ≤2 days per week helps prevent MOH.
• Withdrawal from the overused medication is key, even though symptoms may worsen temporarily.

Keeping a detailed headache diary helps identify potential triggers and patterns. The most relevant information includes timing, intensity, recent food or drink intake, and stress levels.

Rationale for correct answers:

1. Time of onset and end: Assists in identifying patterns and potential environmental or daily routine factors.
2. Severity rating: Tracks how intense headaches are and how they respond to interventions.
3. Food/beverage intake: Certain foods and drinks can act as migraine or headache triggers.
4. Stress events: Emotional or physical stress can precipitate many headache types.

Rationale for incorrect answer:
5. Blood pressure readings three times a day: While extremely high blood pressure can cause headaches, routine BP tracking is not a standard part of a headache diary unless specifically ordered for hypertension evaluation.

Take home points

• The goal of a headache diary is to pinpoint patterns and triggers.
• Focus on timing, severity, diet, stress, and any relevant environmental changes.
• Blood pressure monitoring is only necessary if hypertension is suspected as a contributing factor.

Migraines can be triggered by certain dietary substances, especially foods high in tyramine, nitrates, or other vasoactive compounds. Tyramine, found in aged, fermented, or stored foods such as certain nuts, can cause vasodilation and changes in neurotransmitter release that precipitate migraine attacks. Identifying and avoiding these dietary triggers can help reduce the frequency and severity of headaches.

Rationale for correct answer:
2. Salted cashews: Nuts, particularly when stored for extended periods or salted, can contain elevated levels of tyramine. Tyramine can lead to blood vessel dilation and trigger neurological changes that precipitate migraines in sensitive individuals. Avoidance of such foods is a preventive measure for those prone to migraines.

Rationale for incorrect answers:

1. Baked salmon: Rich in omega-3 fatty acids, salmon is known for its anti-inflammatory properties and is not a common migraine trigger. In fact, omega-3s may help reduce inflammation that can contribute to headache development.

3. Frozen strawberries: Strawberries are not recognized as a typical migraine trigger, and freezing them does not increase migraine risk. While some fruits such as citrus may cause headaches in sensitive individuals, strawberries are generally safe.

4. Fresh asparagus: Asparagus is not associated with migraine onset and provides beneficial nutrients such as folate and antioxidants. Its nutrient profile may support vascular health, which can be beneficial for migraine prevention.

Take home points

• Tyramine-containing foods are a common dietary migraine trigger.
• Fresh, minimally processed foods are less likely to cause headaches.
• Keeping a detailed food diary can help identify individual migraine triggers.

Zolmitriptan is a serotonin receptor agonist (triptan) used for the acute treatment of migraine headaches. It works by causing cranial vasoconstriction and reducing neurogenic inflammation, which relieves migraine pain and associated symptoms. For best results, it should be taken as soon as migraine symptoms begin, rather than waiting until the headache is severe.

Rationale for correct answer:
3. "I should take this medication as soon as I notice symptoms developing.": Early administration of zolmitriptan helps stop the migraine process before it progresses, providing faster and more effective relief. Delaying use may reduce the drug’s effectiveness.

Rationale for incorrect answers:

1. "This medication will relieve my symptoms by causing my blood vessels to dilate.": Triptans relieve migraine symptoms by causing vasoconstriction, not vasodilation. Vasodilation of intracranial vessels is one of the mechanisms believed to contribute to migraine pain.

2. "This medication should prevent the headache from occurring.": Zolmitriptan is not used for migraine prevention; it is prescribed for acute treatment after symptoms appear. Preventive therapy requires different classes of medication such as beta blockers, anticonvulsants, or antidepressants.

4. "I should take this medication to lower my sensitivity to food triggers.": Triptans do not change an individual’s sensitivity to migraine triggers. Avoiding triggers is part of non-pharmacological migraine management, not an effect of zolmitriptan.

Take home points

• Zolmitriptan should be taken at the first sign of migraine symptoms for optimal relief.
• The drug works by vasoconstricting cranial blood vessels and reducing inflammation.
• It is not used for prevention or trigger desensitization; those require separate management strategies.

Cluster headaches are a type of primary headache disorder characterized by severe, unilateral pain, often around the eye or temple, and are accompanied by autonomic symptoms such as nasal congestion, lacrimation, and ptosis. They frequently occur in cyclical patterns or "clusters," with attacks happening at the same time each day, often disrupting the sleep-wake cycle. Recognizing these patterns and associated symptoms is essential for accurate diagnosis and management.

Rationale for correct answers:
2. Client is experiencing altered sleep-wake cycle: Cluster headaches are linked to hypothalamic activation, which can disturb circadian rhythms, resulting in attacks that occur during sleep or at specific times of the day.
3. Headache occurs at approximately the same time of the day: Cluster headaches typically follow a consistent daily pattern, with attacks often occurring at predictable times, such as during early morning hours.
5. Nasal congestion and drainage occur: Ipsilateral autonomic symptoms, including nasal congestion and rhinorrhea, are common due to trigeminal autonomic reflex activation during an attack.

Rationale for incorrect answers:

1. Pain is bilateral across the posterior occipital area: Cluster headache pain is classically unilateral, usually around the orbital or temporal region, not bilateral across the occiput.

4. Client describes headache pain as dull and throbbing: Cluster headaches produce severe, sharp, or stabbing pain, rather than a dull or throbbing quality, which is more typical of migraines.

Take home points

• Cluster headaches are unilateral, severe, and often follow a predictable daily schedule.
• Associated autonomic symptoms (nasal congestion, lacrimation, ptosis) are key diagnostic clues.
• They can disrupt the sleep-wake cycle, often waking clients from sleep during attacks.

Migraine management includes both pharmacological and non-pharmacological interventions to relieve pain and associated symptoms. Applying a cool cloth or ice pack to the face or head can cause local vasoconstriction, which helps reduce pain and discomfort during a migraine attack. This method is safe, easily accessible, and effective as a complementary therapy alongside prescribed medication.

Rationale for correct answer:
4. Apply a cool cloth to the face during a headache: The cold temperature causes vasoconstriction and decreases inflammatory mediator activity, which can help alleviate migraine pain. This is a simple, low-risk measure that clients can use at home for symptom relief.

Rationale for incorrect answers:

1. Use music therapy for relaxation with the onset of the headache: While relaxation techniques can help reduce stress-related headache triggers, music therapy is not typically used during acute migraine pain because sound sensitivity (phonophobia) is common.
2. Increase physical activity when a headache is present: Physical exertion during an active migraine can worsen pain due to increased intracranial blood flow and should be avoided until symptoms resolve.
3. Drink sugar-free beverages to prevent headaches: There is no evidence that sugar-free beverages specifically prevent migraines, and some artificial sweeteners, such as aspartame, may actually trigger headaches in sensitive individuals.

Take home points

• Cold therapy applied to the head or face can help relieve migraine pain through vasoconstriction.
• Avoid physical exertion during an active migraine attack to prevent symptom worsening.
• Be cautious with artificial sweeteners, as they may trigger headaches in some individuals.

Migraine headaches have a strong genetic component, and many clients report a family history of similar headache patterns. Asking about hereditary tendencies can help differentiate migraines from other types of headaches such as cluster or tension headaches. Understanding the client’s family history aids in both diagnosis and preventive care planning.

Rationale for correct answer:
4. Is there a pattern of headaches among family members?: Migraines often run in families due to genetic predisposition affecting vascular and neurological responses. This question can help confirm a likely diagnosis and support early preventive interventions in at-risk individuals.

Rationale for incorrect answers:

1. Do the headaches occur at the same time each day?: This pattern is more characteristic of cluster headaches, which have a predictable daily timing, rather than migraines, which are less time-specific.
2. Is your headache accompanied by profuse facial sweating?: Facial sweating is a typical autonomic symptom of cluster headaches, not migraines.
3. Do you have seasonal headaches?: Seasonal headache patterns are more commonly associated with sinus headaches triggered by allergies or environmental changes, not migraines.

Take home points

• A positive family history is a strong diagnostic clue for migraines.
• Migraines do not typically follow a strict daily schedule like cluster headaches.
• Autonomic or seasonal patterns point toward other headache types, not migraines.

Cluster headaches are characterized by severe, unilateral, periorbital pain accompanied by ipsilateral autonomic symptoms such as lacrimation, conjunctival injection, eyelid edema, and nasal congestion. They often occur in cyclical patterns ("clusters") and are described as sharp, stabbing, or burning in quality. This presentation fits the classic cluster headache profile rather than migraine, tension, or medication overuse headaches.

Rationale for correct answer:

1. Cluster headaches: These headaches present with sudden, severe, unilateral orbital or temporal pain and accompanying autonomic features on the same side, such as eye tearing and eyelid swelling. Attacks typically last 15 minutes to 3 hours and occur in patterns over weeks to months.

Rationale for incorrect answers:
2. Tension headaches: Typically cause bilateral, band-like pressure or tightness, without autonomic symptoms such as eye swelling or tearing. Pain is usually mild to moderate rather than excruciating.
3. Migraine headaches: Often unilateral and may include photophobia, phonophobia, and nausea, but the pain is usually throbbing and not associated with prominent autonomic symptoms like lacrimation and eyelid swelling.
4. Medication overuse headaches: Usually present as chronic daily headaches due to excessive analgesic use; they are diffuse, less intense, and lack the acute, stabbing nature and autonomic features seen here.

Take home points

• Cluster headaches cause severe, unilateral orbital pain with ipsilateral autonomic signs.
• Tension headaches are bilateral and lack autonomic symptoms.
• Migraines are typically throbbing and often accompanied by sensory sensitivities, not localized eye swelling.

An aura is a reversible neurological symptom that can occur before or during a migraine headache. It often manifests as visual disturbances such as flashing lights, zigzag lines, or blind spots, but can also include sensory, speech, or motor changes. Documenting the presence of an aura is important because it helps classify the migraine type and guide treatment planning.

Rationale for correct answer:
2. An aura prior to a migraine headache: An aura represents cortical spreading depression leading to temporary changes in brain activity, which cause visual or sensory disturbances. Recognizing an aura allows the client to take acute migraine medication earlier, potentially reducing headache severity.

Rationale for incorrect answers:

1. A premonition of a migraine headache: While some individuals experience prodromal symptoms hours before a migraine such as mood changes or food cravings, flashing lights are not considered a general premonition, they are specific to aura.

3. A papillary response creating the headache: There is no evidence that a change in pupil size directly causes headaches; this is unrelated to migraine pathophysiology.

4. Intense photophobia prior to the headache onset: Photophobia is light sensitivity that typically occurs during a migraine, not as a visual disturbance beforehand.

Take home points

• Aura is a key diagnostic feature of some migraines, often involving visual changes.
• Documenting aura helps differentiate migraine types and tailor treatment.
• Prodromal symptoms and photophobia are distinct from aura and occur at different migraine stages.

Migraines are often unilateral and throbbing, frequently preceded by prodromal symptoms such as photophobia, phonophobia, mood changes, or food cravings. They have a strong genetic component, with many clients reporting a positive family history. Recognizing this pattern is essential for accurate diagnosis and for implementing both acute and preventive treatment strategies.

Rationale for correct answer:
2. Migraine: Migraines are characterized by recurrent unilateral throbbing pain, often accompanied by neurological or sensory disturbances. A family history is common, and prodromal or aura symptoms (such as light sensitivity) help distinguish migraines from other headache types.

Rationale for incorrect answers:

1. Cluster: Cluster headaches are also unilateral but are described as sharp or stabbing, not throbbing, and are associated with autonomic symptoms like lacrimation and nasal congestion, not photophobia as a prodrome.

3. Frontal-type: This is not a recognized headache classification; headaches limited to the frontal area are often tension or sinus-related, lacking the prodrome and family history pattern of migraines.

4. Tension-type: Tension headaches are typically bilateral, have a pressing or tight quality, and do not involve prodromal symptoms or significant photophobia.

Take home points

• Migraines are often unilateral, throbbing, and have a strong family history link.
• Photophobia can be part of the prodrome or occur during a migraine attack.
• Cluster and tension headaches have distinct patterns and associated symptoms that help differentiate them from migraines.

Cluster headaches are severe, unilateral headaches with an abrupt onset and short duration, typically lasting 15 to 180 minutes. They are characterized by sharp, stabbing pain and often accompanied by ipsilateral autonomic symptoms such as ptosis, lacrimation, nasal congestion, or conjunctival injection. Alcohol is a known trigger during active cluster periods, but it is not the only dietary trigger, and a family history is less common compared to migraines.

Rationale for correct answers:
3. Abrupt onset lasting 5 to 180 minutes: Cluster headaches begin suddenly, peak quickly, and resolve within this time frame, often multiple times a day during a cluster period.
4. Severe, sharp, penetrating head pain: Pain is intense, described as stabbing or burning, usually around one eye or the temple.
6. May be accompanied by unilateral ptosis or lacrimation: Ipsilateral autonomic symptoms such as drooping eyelid and tearing are classic diagnostic clues.

Rationale for incorrect answers:

1. Family history: While possible, a strong family history is more characteristic of migraines than cluster headaches.

2. Alcohol is the only dietary trigger: Alcohol is a potent trigger during a cluster period, but other factors such as strong odors or high altitudes can also provoke attacks.

5. Bilateral pressure or tightness sensation: This description fits tension-type headaches, not cluster headaches, which are unilateral and stabbing in nature.

Take home points

• Cluster headaches have abrupt onset, short duration, and severe unilateral pain.
• Ipsilateral autonomic symptoms (ptosis, lacrimation, nasal congestion) are key identifiers.
• Alcohol is a strong trigger during active cluster periods but is not the sole cause.

Functional headaches, such as migraines and tension-type headaches, are diagnosed primarily through a comprehensive history because no definitive imaging or laboratory test can confirm the diagnosis. A detailed history helps identify the pattern, triggers, duration, quality, and associated symptoms of the headache, which are essential for distinguishing between different headache types and ruling out secondary causes.

Rationale for correct answer:
4. Thorough history of the headache: Collecting detailed information about onset, location, quality, duration, aggravating and relieving factors, and associated symptoms is the cornerstone of diagnosing functional headaches. This method allows for classification and guides treatment decisions.

Rationale for incorrect answers:

1. CT scan: Useful for ruling out structural brain lesions or acute intracranial pathology but does not confirm functional headaches.
2. Electromyography (EMG): May detect muscle tension but is not a primary diagnostic tool for headaches and cannot differentiate headache types reliably.
3. Cerebral blood flow studies: Occasionally used in research or to rule out vascular abnormalities, but not routinely indicated for diagnosing functional headaches.

Take home points

• A thorough clinical history is the gold standard for diagnosing functional headaches.
• Imaging and specialized studies are reserved for ruling out secondary causes.
• Accurate history-taking supports correct classification and effective management.

Specific serotonin receptor agonists, also known as triptans, are used in the acute treatment of both migraine and cluster headaches. They work by stimulating 5-HT₁B/1D receptors, leading to cranial vasoconstriction, inhibition of neuropeptide release, and reduced inflammation within the trigeminovascular system. These actions directly target the pathophysiologic mechanisms responsible for pain generation in these headaches.

Rationale for correct answer:
4. Specific serotonin receptor agonists such as sumatriptan (Imitrex): Triptans are first-line agents for acute migraine attacks and can also be effective in aborting cluster headache attacks. Their mechanism addresses the vascular and neurogenic inflammation processes that underlie these headaches.

Rationale for incorrect answers:

1. β-Adrenergic blockers such as propranolol (Inderal): Used for prophylaxis of migraines, not for acute treatment; they do not reverse ongoing headache pathophysiology.

2. Serotonin antagonists such as methysergide (Sansert): Previously used for migraine prevention but associated with significant adverse effects; not used for acute relief.

3. Tricyclic antidepressants such as amitriptyline (Elavil): Effective for migraine prevention, especially in patients with comorbid depression or insomnia, but not useful for acute attacks.

Take home points

• Triptans are the mainstay for acute treatment of migraines and can abort cluster headaches.
• They work by vasoconstricting cranial vessels and reducing neurogenic inflammation.
• Preventive medications differ from acute therapies and are chosen based on headache type and frequency.

Migraines are characterized by unilateral, throbbing pain that may be preceded by an aura, such as flashing lights, zigzag lines, or sensory disturbances. They have a strong genetic component, with many clients reporting a family history of similar headaches. The presence of an aura helps classify the condition as migraine with aura, which requires specific management strategies to treat acute attacks and prevent recurrence.

Rationale for correct answer:
4. Migraine headache: This headache type is often unilateral, pulsating, and moderate to severe in intensity. The presence of aura, particularly visual changes, along with family history, is strongly indicative of migraine rather than other headache types.

Rationale for incorrect answers:

1. Cluster headache: Typically presents with severe unilateral orbital or temporal pain accompanied by autonomic symptoms (lacrimation, nasal congestion) but not with aura.
2. Tension-type headache: Usually bilateral with a pressing or tightening quality and without aura or strong family history association.
3. Medication overuse headache: Occurs in individuals who take frequent headache medications; pain is usually diffuse and lacks aura.

Take home points

• Migraine with aura involves neurological symptoms before headache onset.
• A strong family history supports the diagnosis.
• Other headache types (cluster, tension, medication overuse) have distinct patterns and lack classic aura features.

Effective migraine management includes lifestyle modifications that promote consistency, trigger avoidance, and stress reduction. Regular sleep patterns help regulate the body’s circadian rhythm and reduce the likelihood of migraine onset. Avoiding personal triggers—such as certain foods, environmental stimuli, or smells—can prevent attacks. Applying cold compresses to the head or neck can relieve pain by reducing inflammation and numbing the area. Relaxation techniques like meditation and deep breathing decrease stress, a common migraine trigger.

Rationale for correct answers:

1. Maintain a regular sleep schedule: Irregular sleep patterns are a common migraine trigger. Consistent sleep-wake times help prevent attacks.

2. Avoid known triggers: Individual triggers vary but often include foods (e.g., aged cheese, chocolate), odors, and sensory stimuli. Avoidance is an effective prevention method.

3. Cold compress: Reduces vasodilation and provides analgesic relief during migraine attacks.

5. Relaxation techniques: Deep breathing, progressive muscle relaxation, and meditation reduce stress-induced migraines.

Rationale for incorrect answers:
4. Increase caffeine intake: While small amounts of caffeine may abort early migraine symptoms, excessive or frequent intake can trigger rebound headaches.
6. Engage in strenuous physical activity at the first sign of an aura: Intense activity can worsen migraine pain and is not recommended during an aura or headache phase.

Take home points

• Prevention strategies focus on routine, trigger avoidance, and stress management.
• Cold therapy is a safe, effective acute measure.
• Overuse of caffeine or intense exercise during a migraine can worsen symptoms.

A sudden onset of the "worst headache of my life," accompanied by a stiff neck and photophobia, is a medical emergency. These symptoms may indicate a subarachnoid hemorrhage or another serious intracranial pathology. Immediate neuroimaging, preferably a CT scan, is critical to confirm the diagnosis and initiate urgent treatment to prevent death or irreversible neurological damage. Delays in diagnosis can be fatal.

Rationale for correct answer:
3. Prepare the client for immediate diagnostic imaging, such as a CT scan: A non-contrast CT scan is the first-line diagnostic tool for suspected intracranial hemorrhage because it is fast, widely available, and highly sensitive for detecting acute bleeding. Early identification allows for rapid intervention, such as neurosurgical evaluation or aneurysm repair.

Rationale for incorrect answers:

1. Administer prescribed pain medication to manage the severe pain: While pain relief is important, it should not delay diagnostic testing for a potentially life-threatening emergency. Analgesia may also mask worsening neurological symptoms.

2. Obtain a detailed history of the client's headache patterns and triggers: History-taking is secondary in emergencies. Immediate imaging takes priority over gathering detailed historical data in this scenario.

4. Educate the client on the importance of headache diaries for tracking symptoms: Education is appropriate for long-term headache management but is irrelevant during an acute neurological emergency.

Take home points

• Sudden severe headaches with neck stiffness and photophobia are red flags for subarachnoid hemorrhage.
• Non-contrast CT scan is the initial diagnostic tool of choice in suspected intracranial bleeding.
• In emergencies, diagnosis and stabilization always take priority over symptom management and patient education.

Cluster headaches are characterized by severe, unilateral pain, often around one eye, and are typically short in duration but recur in clusters. First-line acute treatment is inhalation of 100% oxygen via a non-rebreather mask at 6–12 L/min for 15–20 minutes. Oxygen therapy is effective in aborting attacks in many patients by causing cerebral vasoconstriction and modulating neurotransmitter activity.

Rationale for correct answer:
4. Inhaling 100% oxygen at the onset of the headache: Rapid, high-flow oxygen is highly effective for acute cluster headache relief, with minimal side effects. It should be administered as soon as the headache starts to maximize effectiveness.

Rationale for incorrect answers:

1. Applying a warm compress to the face and temples: Heat generally worsens vasodilation and may aggravate cluster headache pain. Cold compresses are sometimes used for symptom relief but are not first-line therapy.
2. Resting in a dark, quiet room until the pain subsides: This is more beneficial for migraines, not cluster headaches, which are typically short, intense, and not relieved by rest.
3. Taking a high-dose oral analgesic as soon as symptoms begin: Oral analgesics are often too slow-acting to help with cluster headaches due to their rapid onset and short duration.

Take home points

• High-flow 100% oxygen is the gold standard for acute cluster headache relief.
• Cluster headaches differ from migraines in both presentation and effective treatment strategies.
• Rapid treatment at headache onset is critical for effectiveness.
