Extract:
Question 1 of 5
A client with peptic ulcer disease receives a new prescription for cimetidine. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Smoking exacerbates peptic ulcer disease, and reducing to a pack per day is insufficient. The client should be encouraged to quit smoking entirely. Other statements reflect appropriate understanding of cimetidine administration and side effect monitoring.
Question 2 of 5
A client with generalized anxiety disorder (GAD) receives a new prescription for lorazepam. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Stopping lorazepam abruptly if effects are not immediate is incorrect. Lorazepam may take time to achieve full effect, and sudden cessation can cause withdrawal symptoms. The client needs instruction to follow the prescribed regimen and consult the provider if concerns arise.
Question 3 of 5
The nurse is educating a client about acetaminophen. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Taking additional acetaminophen doses as needed is dangerous due to the risk of liver toxicity from exceeding the maximum daily dose. The client needs instruction to adhere to prescribed dosing and consult the provider before adjusting doses.
Question 4 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: A
Rationale: Atorvastatin lowers LDL cholesterol, a key risk factor for coronary artery disease. A decrease in LDL levels indicates the medication is effectively reducing cardiovascular risk, making it the primary indicator of therapeutic success.
Question 5 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 (DW) 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: Concentration = 4000 mg / 500 mL = 8 mg/mL. Infusion rate = Prescribed dose (300 mg/hour) / Concentration (8 mg/mL) = 37.5 mL/hour.
