Question 1 of 5
Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Correct Answer: D
Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after to prevent hypoglycemia. Synchronizing meal timing is critical. Glucose sources, monitoring, and hypoglycemia checks are secondary.
Question 2 of 5
The nurse is administering the muscle relaxant baclofen by mouth (PO) to a client diagnosed with multiple sclerosis. Which intervention should the nurse implement?
Correct Answer: A
Rationale: Baclofen causes dizziness and weakness, increasing fall risk. Advising slow, cautious movement prevents injuries. Intake/output, stopping antispasmodics, or frequent strength checks are less relevant.
Question 3 of 5
The nurse is teaching a client who has been diagnosed with HIV about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: D
Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission. Safe practices are needed. Other statements are accurate regarding HIV management.
Question 4 of 5
The nurse is assessing a client who was recently diagnosed with Parkinson’s disease and is taking carbidopa-levodopa. The client is concerned that the medication is not working. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: Clarifying the client’s concern about carbidopa-levodopa’s effectiveness guides targeted assessment. Urine color, dyskinesia, or meal timing are secondary until the specific issue is understood.
Question 5 of 5
A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 1.7
Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.
