A patient in the emergency department reports taking sildenafil (Viagra) and nitroglycerin 1 hr before sexual activity. Which finding should the nurse immediately report to the physician?
- A. WBC of 3200 units/L
- B. RR of 26 breaths/min
- C. Temp of 38°C
- D. BP of 70/50
Correct Answer: D
Rationale: The correct answer is D: BP of 70/50. When sildenafil (Viagra) is taken with nitroglycerin, it can cause severe hypotension that is unresponsive to treatment. The combination of these medications can lead to a dangerous drop in blood pressure. It is crucial to immediately report hypotension in this scenario. It is recommended to allow at least 24 hours to elapse between the last dose of sildenafil and nitroglycerin to prevent such adverse effects. The other vital signs and lab values may be abnormal but do not have the immediate life-threatening implications that severe hypotension does in this context.
