Question 4 of 5
When the nurse is obtaining this client's health history, which question about pain is least helpful?
Correct Answer: D
Rationale: Asking about pain medications is less critical in the acute MI setting compared to timing, location, and triggers, which guide diagnosis and urgency.
Question 5 of 5
An adult who is admitted for a cardiac catheterization asks the nurse if she will be asleep during the cardiac catheterization. What is the best initial response for the nurse to make?
Correct Answer: B
Rationale: During cardiac catheterization, clients receive sedation but remain awake, as their cooperation may be needed. General anesthesia is not used, and pain is managed with sedation, not additional anesthetics. Asking 'why' may make the client defensive and does not provide the requested information.
