HESI RN Med Surg Exam 2 Questions
Extract:
Question 1 of 5
A client receives a prescription for 2 liters of lactated Ringer's IV to be infused over 12 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion?
Correct Answer: A
Rationale: The correct answer is A (56 gtt/min). Calculation: 2000 mL ÷ 12 hr = 166.67 mL/hr; 166.67 mL/hr × 20 gtt/mL = 3333.4 gtt/hr; 3333.4 gtt/hr ÷ 60 min/hr = 55.56 gtt/min, rounded to 56 gtt/min. This ensures accurate IV infusion.
Question 2 of 5
A client asks the nurse for information about how to reduce risk factors for benign prostatic hyperplasia (BPH). Which information should the nurse provide?
Correct Answer: D
Rationale: The correct answer is D because physical activity reduces BPH risk by supporting prostate health.

Choice B lacks evidence for BPH risk reduction.
Choice C is not strongly supported for BPH prevention.
Question 3 of 5
When teaching a client with Parkinson's disease, which rationale for the prescription of carbidopa-levodopa should the nurse include?
Correct Answer: D
Rationale: The correct answer is D because carbidopa-levodopa replenishes dopamine, improving motor function in Parkinson's disease.

Question 4 of 5
Four days following an abdominal aortic aneurysm repair, the client is exhibiting edema of both lower extremities, and pedal pulses are not palpable. Which action should the nurse implement first?
