The nurse is preparing to administer an IM dose of vitamin B1 (Thiamine) to a male client experiencing acute alcohol withdrawal and peripheral neuritis. The client belligerently states, "What do you think you're doing?" How should the nurse respond?

A. Explaining that the shot will help relieve foot pain addresses the client’s peripheral neuritis directly and provides a clear, truthful reason for the injection, which can reduce resistance. B. Withholding medication until the client calms down delays needed treatment and does not address the client’s concerns. C. Saying the shot will make the client feel calmer is misleading; thiamine does not treat agitation but prevents and treats neurological complications of alcoholism such as Wernicke’s encephalopathy and neuritis. D. Offering self-administration is inappropriate in this context, especially for a client in acute alcohol withdrawal who may not be capable of safe self-injection.
