RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: D
Rationale: Atorvastatin lowers LDL cholesterol, reducing coronary artery disease risk. Decreased LDL levels indicate effectiveness. HDL, PT, and CK are not primary measures of atorvastatin’s therapeutic effect.
Question 2 of 5
A client with chronic lower back pain has been taking ibuprofen PO twice a day for several months. Which assessment is most important for the nurse to complete?
Correct Answer: A
Rationale: Long-term ibuprofen use risks gastrointestinal bleeding or ulcers. Assessing for abdominal pain detects these serious side effects. Pulse volume, pain levels, or sleep patterns are less critical to NSAID-related complications.
Question 3 of 5
The nurse is teaching a client who has been diagnosed with human immunodeficiency virus (HIV) about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: C
Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission; safe practices are still needed. The other statements are accurate regarding HIV management and ART benefits.
Question 4 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.
Question 5 of 5
A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
Correct Answer: A
Rationale: Scopolamine prevents postoperative nausea, not pain. Explaining its purpose clarifies the client’s misunderstanding. New patches, expired effects, or placement checks do not address the pain, which requires separate analgesia.
