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: D
Rationale: While antiretroviral therapy (ART) significantly reduces HIV transmission risk by lowering viral load, it does not completely prevent it. The client needs clarification that even with an undetectable viral load, transmission is possible, and preventive measures like safer sex practices are still necessary.
Question 2 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 3 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.
Question 4 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 must be taken with plain water and no food or other beverages for at least 30 minutes to ensure proper absorption. Milk can interfere with absorption, so the nurse should instruct the client accordingly.
Question 5 of 5
A female client with a history of peptic ulcer disease receives a prescription for misoprostol. Which information provided by the client indicates to the nurse a need for further teaching?
Correct Answer: B
Rationale: Misoprostol is used to prevent ulcers, not timed with the menstrual cycle. Starting therapy based on the cycle is incorrect and requires teaching. Other statements reflect correct understanding of misoprostol’s risks and precautions in women of childbearing age.
