Explanation

Diazepam is a benzodiazepine medication used to treat anxiety disorders. It works by enhancing the activity of certain neurotransmitters in the brain. A therapeutic outcome for this medication would be a decrease in anxiety and an improved ability to cope with stress.
Option B is not correct because it does not indicate whether the medication is eﬀective or not.
Option C is not correct because it indicates that the client does not see a change in their symptoms.
Option D is not correct because it indicates that the client is self-medicating and increasing their dose without consulting their healthcare provider.

A. A paradoxical reaction related to the body's attempt to maintain homeostasis, and it will resolve over time. B. An allergic response and the medication should be stopped. C. A random idiosyncratic reaction that will not disrupt the treatment plan. D. A hypersensitive (excessive) response and the dose should be reduced.

Correct Answer is B

Explanation

The sudden development of hives in a client taking phenytoin is most likely an allergic response to the medication. In this case, the medication should be stopped and the healthcare provider should be notified.
Option A is incorrect because a paradoxical reaction is not related to the development of hives.
Option C is incorrect because an idiosyncratic reaction is unpredictable and can disrupt the treatment plan.
Option D is incorrect because a hypersensitive response would require more than just reducing the dose; the medication should be stopped.
