Question 1 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 2 of 5
A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Correct Answer: B
Rationale: Erythromycin may reduce oral contraceptive efficacy. Additional contraception (e.g., condoms) prevents pregnancy. Stopping contraceptives, spacing doses, or avoiding sunlight are incorrect.
Question 3 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 4 of 5
The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?
Correct Answer: A
Rationale: Mydriatics dilate pupils, causing photophobia. A dimly lit room reduces discomfort from light sensitivity. Warm temperatures, humid air, or quiet environments do not address this primary issue.
Question 5 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.
