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.

Correct Answer is ["A","D"]
Explanation
A. Tolerance can develop over time and lead to the need for higher doses – This is correct because long-term use of clonazepam, like other benzodiazepines, can result in tolerance, potentially necessitating higher doses to achieve the same therapeutic effect.
B. Skip a dose if you need to drive – This is incorrect. Clients should be advised to take their medication as prescribed and consult their healthcare provider about driving, as clonazepam can impair coordination and reaction times.
C. Skip a dose if you plan to go out drinking with friends – This is incorrect. While it’s important to avoid alcohol when taking clonazepam due to the increased risk of sedation and respiratory depression, clients should not skip doses without consulting their healthcare provider.
D. Do not try to taper yourself off this medication without physician guidance – This is correct. Stopping clonazepam suddenly can lead to withdrawal symptoms and seizure recurrence, so any changes in medication should always be done under the guidance of a healthcare provider.
