A client taking phenytoin suddenly develops hives. The nurse understands which of the following explains this occurrence.
A paradoxical reaction related to the body's attempt to maintain homeostasis, and it will resolve over time.
An allergic response and the medication should be stopped.
A random idiosyncratic reaction that will not disrupt the treatment plan.
A hypersensitive (excessive) response and the dose should be reduced.
The Correct Answer is B
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.
