HESI RN 301 Pharmacology Final Exam Questions
Extract:
Question 1 of 5
A client with hepatic encephalopathy is receiving lactulose. Which assessment provides the nurse with the best information to evaluate the client's therapeutic response to the medication?
Correct Answer: D
Rationale: Lactulose reduces ammonia in hepatic encephalopathy, so monitoring serum ammonia and electrolytes (due to laxative effects) best evaluates response. Glucose, stool, and hepatic enzymes are less direct indicators.
Question 2 of 5
A client is receiving morphine sulfate via a patient-controlled analgesia (PCA) pump postoperatively. Which assessment finding should prompt the nurse to administer a prescribed PRN dose of naloxone?
Correct Answer: B
Rationale: A respiratory rate of 7 breaths/minute indicates severe opioid-induced respiratory depression, requiring naloxone. Other findings suggest distress but are less specific for opioid overdose.
Question 3 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: C
Rationale: Risedronate requires an empty stomach and water only to ensure absorption. Milk’s calcium reduces efficacy. Withholding until breakfast, consulting the pharmacist, or providing milk are incorrect.
Question 4 of 5
A client who has dysphagia after a cerebral vascular accident (CVA) receives a new prescription for lansoprazole capsules via nasogastric tube (NGT). Which action should the nurse implement prior to administering the medication?
Correct Answer: A
Rationale: Lansoprazole granules are mixed with water for NGT administration to ensure proper delivery. Tablets are unsuitable, crushing alters efficacy, and applesauce is inappropriate for tube administration.
Question 5 of 5
Based on the capillary glucose measurement, a client is to receive 10 units of regular insulin. The client's medication drawer contains one vial of a 70/30 mixture of regular insulin and isophane insulin. How should the nurse prepare the prescribed dose?
Correct Answer: C
Rationale: A 70/30 vial contains 30% regular insulin, so 10 units yields only 3 units regular insulin. Withholding until regular insulin is available ensures accurate dosing.
