Which of the following medications is most commonly used to treat acute migraine attacks?
Triptans
Antidepressants
Antibiotics
Beta-blockers
The Correct Answer is A
A. Triptans: Triptans are selective serotonin receptor agonists that constrict cranial blood vessels and reduce inflammation, directly relieving acute migraine symptoms. They are first-line therapy for moderate to severe migraine attacks and provide rapid symptom relief, including headache and associated nausea or sensitivity to light.
B. Antidepressants: Antidepressants, such as amitriptyline, are primarily used for migraine prevention rather than acute treatment. They modulate neurotransmitters to reduce migraine frequency over time but do not provide immediate relief during an active attack.
C. Antibiotics: Antibiotics have no role in treating migraines because migraine pathophysiology is neurologic and vascular, not infectious. Using antibiotics would not alleviate pain or associated migraine symptoms and could contribute to unnecessary side effects.
D. Beta-blockers: Beta-blockers, such as propranolol, are used for migraine prophylaxis to prevent future attacks, not for acute symptom relief. They work by reducing sympathetic nervous system activity but do not provide immediate relief once a migraine has started.

Correct Answer is B
Explanation
A. Administer a rapid acting insulin: Giving additional insulin would worsen hypoglycemia and could lead to serious complications. The patient’s symptoms suggest low blood glucose, so administering more insulin is unsafe and not indicated at this time.
B. Perform bedside glucose testing.: Checking the patient’s blood glucose provides objective data to confirm hypoglycemia. This allows the nurse to determine the appropriate intervention, such as administering glucose orally or intravenously, ensuring safe and targeted treatment.
C. Notify the kitchen to deliver the tray.: While providing food is important, waiting for the tray without confirming blood glucose could delay treatment of hypoglycemia. Immediate assessment of glucose is required before feeding.
D. Give the patient orange juice.: Administering juice may be appropriate if hypoglycemia is confirmed, but giving it before verifying blood glucose could mask other causes of tremors and nervousness. Assessment first ensures safe and effective intervention.
Correct Answer is ["10\u201320"]
Explanation
10–20 mcg/mL: This is the established therapeutic range for phenytoin (Dilantin) in serum. Maintaining levels within this range ensures adequate seizure control while minimizing toxicity. Levels below 10 mcg/mL may be ineffective, and levels above 20 mcg/mL increase the risk of adverse effects such as nystagmus, ataxia, and confusion.
