The nurse is preparing to administer a muscle relaxant to a client with a fracture. What question should the nurse ask before administering the medication?

A. "Do you have any allergies to iodine or shellfish?": Allergies to iodine or shellfish are relevant for contrast media or certain imaging procedures, not for muscle relaxants. Asking this question does not address potential interactions or contraindications with the prescribed medication. B. "Are you currently taking any other medications?": Muscle relaxants can interact with other CNS depressants, antihypertensives, or certain antibiotics, increasing sedation, hypotension, or toxicity risk. Reviewing all current medications helps prevent adverse drug interactions and ensures safe administration. C. "Have you experienced any recent changes in your vision?": Visual changes are not a common concern prior to administering most muscle relaxants. While some medications can rarely cause blurred vision, this is not a standard pre-administration assessment question. D. "Have you been exposed to any sick individuals recently?": Exposure to infectious agents does not directly influence the safety or effectiveness of muscle relaxants. This question is more relevant for immune-compromised clients or infection control rather than routine medication administration.
