Question 1 of 5
The nurse responds to the call light of a client who has a history of angina pectoris. He tells the nurse that he has just taken a nitroglycerin tablet sublingually for anginal pain. What action should the nurse take next?
Correct Answer: A
Rationale: If anginal pain persists five minutes after the first nitroglycerin tablet, a second tablet should be administered, with up to three doses at five-minute intervals. Positioning with head lower than feet, narcotics, or calling the physician are not the immediate next steps.

Question 3 of 5
Which assessment finding should signal the nurse to withhold applying the client's nitroglycerin patch and notify the physician?
