A nurse is caring for a client who has heart failure and respiratory arrest. What should be the nurse’s first action?
Auscultate for breath sounds.
Establish an open airway.
Establish IV access.
Feel for a carotid pulse.
The Correct Answer is B
Establishing an open airway is the most crucial and immediate action in any respiratory arrest situation, including when a client has heart failure. Here's a detailed explanation: 1. Airway patency is paramount for survival: Oxygen, the essential element for life, cannot reach the lungs and bloodstream without a clear and unobstructed airway. Brain cells are extremely sensitive to oxygen deprivation and start to die within minutes without it, leading to irreversible brain damage or death. 2. Respiratory arrest in heart failure: Heart failure often leads to fluid buildup in the lungs (pulmonary edema), which can significantly impair breathing. Respiratory arrest can occur due to: Excessive fluid accumulation in the lungs. Weakening of respiratory muscles due to fatigue or heart failure itself. Arrhythmias or heart blocks affecting heart's ability to pump effectively. 3. Steps to establish an open airway: Head tilt-chin lift maneuver: Gently tilt the head back and lift the chin to open the airway. Jaw thrust maneuver: If a neck injury is suspected, use the jaw thrust maneuver to avoid further injury. Removal of any visible obstructions: Clear any visible foreign objects or fluids from the mouth or throat. Use of airway adjuncts: Consider using oral or nasal airways to maintain airway patency, especially if the patient is unconscious.
4. Rationale for other choices:
A. Auscultating for breath sounds: While important for assessment, it does not address the immediate need to establish airflow.
C. Establishing IV access: IV access is necessary for medications and fluids, but airway takes priority in respiratory arrest.
D. Feeling for a carotid pulse: Checking for a pulse is essential, but only after ensuring an open airway and attempting to restore breathing.
5. Importance of prioritizing airway: Establishing an open airway allows for potential rescue breaths and ventilation, which can help restore oxygen levels and prevent further deterioration. Even if a pulse is present, without a clear airway, oxygen cannot reach the vital organs, leading to organ failure and death.

Correct Answer is A
Explanation
Choice A rationale:
Chronic pain can manifest in various behavioral and physical symptoms, including restlessness, pacing, grimacing, and other facial expressions of pain. These behaviors are often unconscious attempts to cope with or distract from the pain.
They may also reflect the emotional distress that often accompanies chronic pain. Patients may feel frustrated, anxious, or even depressed due to the persistent nature of their pain and its impact on their lives.
It's crucial for nurses to recognize these behavioral signs of pain, as patients may not always readily report their pain verbally. By observing these behaviors, nurses can assess the patient's pain level more accurately and provide appropriate interventions.
Choice B rationale:
Chronic pain is defined as pain that persists for longer than three months, often for much longer. It is not limited and short in duration.
This distinguishes it from acute pain, which is typically associated with an injury or illness and resolves within a few days or weeks.
Choice C rationale:
While some patients with chronic pain may have physical signs of tissue injury, this is not always the case. Chronic pain can also be caused by nerve damage, inflammation, or changes in the central nervous system.
In some cases, the underlying cause of chronic pain may be unknown.
Choice D rationale:
Although chronic pain may not always cause a significant change in vital signs, it can still be a very real and debilitating experience for patients.
Vital signs, such as heart rate, blood pressure, and respiratory rate, are often more sensitive to acute pain.
Nurses should not rely solely on vital signs to assess chronic pain. Instead, they should consider the patient's self-report of pain, behavioral cues, and other factors.
Correct Answer is B
Explanation
Choice A rationale:
Awaiting biopsy results can certainly cause anxiety and stress, but it doesn't directly impact the physiological mechanisms that modulate pain perception.
While a patient awaiting biopsy results may be more attentive to their bodily sensations, including pain, the anxiety itself is not the primary driver of a lowered pain threshold.
It's important to address the patient's concerns and provide emotional support, but this alone may not be sufficient to manage pain effectively if anxiety is not the primary factor.
Choice B rationale:
Anxiety activates the sympathetic nervous system, which triggers the "fight-or-flight" response. This cascade of physiological changes includes:
Increased heart rate and blood pressure Muscle tension
Dilated pupils
Heightened awareness of bodily sensations
These physiological changes can amplify pain signals and lower the pain threshold, meaning that a person who is anxious may perceive pain more intensely than someone who is calm and relaxed.
This is because anxiety can reduce the effectiveness of the body's natural pain-inhibiting mechanisms, such as the release of endorphins and serotonin.
Choice C rationale:
Difficulty sleeping can also contribute to pain, but its effect on pain threshold is less direct than that of anxiety. Sleep deprivation can lead to:
Increased irritability Decreased pain tolerance Impaired cognitive function
These factors can make it more difficult to cope with pain, but they don't directly lower the threshold at which pain signals are perceived.
Choice D rationale:
Pain threshold varies among individuals due to a variety of factors, including: Genetics
Past experiences with pain Psychological factors Cultural beliefs
Coping mechanisms
It is incorrect to assume that all patients who have had surgery will have the same pain threshold.
