Correct Answer: C

Rationale: Rationale for Correct Answer (C): Promoting activity is the most prioritized nursing intervention for a client with CHF. Activity helps improve cardiac function, decreases fluid accumulation, and enhances overall cardiovascular health. It also prevents complications like muscle weakness and deconditioning. It is crucial in managing CHF symptoms and improving the client's quality of life. Summary of Incorrect Choices: A: Administering diuretics helps in reducing fluid overload but does not address the underlying issue of improving cardiac function through physical activity. B: Limiting fluid intake is important, but promoting activity takes precedence as it directly impacts cardiac function and fluid accumulation. D: Maintaining fluid balance is necessary but is a broad concept that includes various interventions, with promoting activity being more focused and critical in CHF management.

Correct Answer: A

Rationale: The correct answer is A: Administer epinephrine. This is the first step in the care of a client with a severe allergic reaction because epinephrine is the primary medication used to reverse the life-threatening symptoms of anaphylaxis. Epinephrine acts quickly to constrict blood vessels, relax smooth muscles in the lungs to improve breathing, and increase heart rate. Administering epinephrine promptly can prevent progression to severe outcomes like respiratory failure or shock. Corticosteroids (B and C) are used as adjunct therapy and do not provide immediate relief. Applying a cold compress (D) does not address the systemic effects of anaphylaxis and can delay potentially life-saving treatment.

Correct Answer: B

Rationale: Step 1: The nurse should prioritize collecting data based on the client's acuity to address immediate needs and ensure patient safety. Step 2: Acuity determines the urgency and intensity of care required, guiding the assessment focus. Step 3: Time available or client cooperation may influence the depth of assessment but do not dictate the data collected. Step 4: The onset of symptoms is important for history-taking but not the primary factor in determining assessment data.

Correct Answer: B

Rationale: The correct answer is B because conveying respect for differences helps build trust and encourages patients to share their perspectives openly. This fosters a positive patient-provider relationship and enhances communication. Choice A is incorrect as patients have unique behaviors. Choice C is incorrect as cultural expectations do not fully explain individual differences. Choice D is incorrect as expressing one's culture is not solely dependent on exposure to Canadian values.

Correct Answer: A

Rationale: The correct answer is A: Assess the client's airway. This is the first action because airway patency is the top priority in any emergency situation, including a suspected stroke. Ensuring the client can breathe effectively is crucial to prevent hypoxia and further complications. Administering oxygen (choice B) may be necessary after assessing the airway. Administering aspirin (choice C) should be done after a definitive diagnosis of an ischemic stroke. Performing a CT scan (choice D) is important for diagnosis but is not the first action to take in a suspected stroke scenario.
