A client has been taking Viagra and is now experiencing angina. The physician has prescribed nitroglycerin p.r.n. for the angina. Which of the following should the nurse include in the discharge instructions?

Correct Answer: A

Rationale: Viagra and nitroglycerin (A) together cause severe hypotension; a 24-hour gap is required. Other options (B, C, D) are incorrect per manufacturer guidelines.

Correct Answer: D

Rationale: The spleen, while important for immune function and blood filtering, is not essential for life; people can survive without it (e.g., after splenectomy). The liver, pancreas, and heart are vital for metabolism, digestion, and circulation.

Correct Answer: B

Rationale: Checking for pitting (indentation after pressure) directly assesses edema severity in an extremity, indicating fluid retention extent. Weighing tracks overall fluid, measuring sizes is less specific, and I/O is indirect.

Correct Answer: C

Rationale: Successful smoking cessation is strongly tied to planning for relapses (e.g., identifying triggers and coping strategies), as it addresses the chronic nature of addiction. Support groups (A) help but are less critical, and B and D ignore the need for comprehensive approaches.

Correct Answer: B

Rationale: Customizing teaching to the learner’s interests enhances engagement and relevance, optimizing learning for an older adult. A overwhelms, C is a tool not a strategy, and D contradicts primacy effect (key info first).
