Question 1 of 5
When administering zolpidem to an older client, which computer documentation indicates that the desired outcome has been achieved?
Correct Answer: A
Rationale: Zolpidem, a sedative-hypnotic, treats insomnia. Sleeping soundly indicates effectiveness. Incontinence, concentration, and outbursts are unrelated to zolpidem’s action.
Question 2 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg subcutaneously twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'enoxaparin sodium injection, USP 60 mg/0.6 mL'. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Calculate: (80 mg ÷ 60 mg) × 0.6 mL = 0.8 mL. The nurse should administer 0.8 mL to deliver 80 mg of enoxaparin.
Question 3 of 5
A client with multiple sclerosis starts a new prescription, baclofen, to control muscle spasticity. Three days later, the client calls the clinic nurse and reports feeling fatigued and dizzy. Which instruction should the nurse provide?
Correct Answer: D
Rationale: Baclofen’s common side effects include fatigue and dizziness, which may subside with time. Avoiding hazardous activities prevents injury. Fluids/protein, stopping abruptly, or ER visits are inappropriate without severe symptoms.
Question 4 of 5
The nurse is administering sevelamer during lunch to a client with chronic kidney disease (CKD). The client asks the nurse to bring the medication later. The nurse should describe which action of sevelamer as an explanation for taking it with meals?
Correct Answer: D
Rationale: Sevelamer binds dietary phosphorus in the gut, reducing absorption in CKD to prevent hyperphosphatemia. Taking with meals ensures binding. Reflux, acid buffering, and indigestion are unrelated.
Question 5 of 5
A client recently diagnosed with Parkinson's disease receives a new prescription for carbidopa-levodopa, a dopaminergic drug. To reduce the client's risk for injury, which instruction should the nurse provide?
Correct Answer: C
Rationale: Carbidopa-levodopa can cause orthostatic hypotension, increasing fall risk. Caution during position changes prevents dizziness or fainting. Beds, rugs (tripping hazard), or assistive devices are not universally needed.
