Answer to Question 1

A
Feedback:
Nitrates and phosphodiesterase enzyme type 5 inhibitors decrease blood pressure, and the combined effect can produce profound, life-threatening hypotension.

Answer to Question 2

C
Feedback:
Nonsteroidal anti-inflammatory agents in long-term use can cause renal impairment. The patient should be assessed for renal impairment with the elevation of the serum BUN and creatinine. NSAIDs do not affect renin and aldosterone levels. A 24-hour urine for microalbumin is not recommended when administering ibuprofen. A complete blood count may not be necessary.
