RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 2 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 pg/dL (6 to 47 μmol/dL)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
Question 3 of 5
A client receives a prescription for penicillin 2 million units IM. The available vial is labeled, '600,000 units/2 mL.' How many mL should the nurse administer? (Enter numeric value only.)
Correct Answer: 4
Rationale:
To calculate: (2,000,000 units prescribed) ÷ (600,000 units/2 mL) = 2,000,000 × 2 ÷ 600,000 = 4 mL. The nurse should administer 4 mL to deliver the prescribed 2 million units.
Question 4 of 5
Which action should the nurse implement to assess the effectiveness of amlodipine?
Correct Answer: A
Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure to manage hypertension. Measuring blood pressure directly assesses its effectiveness. Calcium levels, electrolytes, or intake/output are not primary indicators of amlodipine’s therapeutic effect.
Question 5 of 5
The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?
Correct Answer: D
Rationale: Risedronate requires a full glass of water on an empty stomach, with the client upright for 30 minutes, to ensure absorption and prevent esophageal irritation. Milk or food reduces bioavailability, making water the only appropriate accompaniment.
