A nurse is caring for a client in the emergency department who has a preliminary diagnosis of a transient ischemic attack (TIA). Which of the following diagnostic testing should the nurse anticipate the provider to prescribe?

A. Diarrhea:

Diarrhea is not a common side effect of phenytoin. While gastrointestinal disturbances such as nausea, vomiting, and constipation may occur, diarrhea is less common. Therefore, it is not a primary adverse effect that the nurse should instruct the client to monitor and report.

B. Wrist pain:

Wrist pain is not a common side effect of phenytoin. Side effects related to musculoskeletal issues such as joint pain, muscle weakness, or muscle twitching can occur, but wrist pain specifically is not commonly associated with phenytoin use. Therefore, it is not a primary adverse effect that the nurse should instruct the client to monitor and report.

C. Skin rash:

Skin rash is a potential adverse effect of phenytoin that should be monitored and reported. Phenytoin can cause various skin reactions, including a mild rash or more severe reactions such as Stevens-Johnson syndrome or toxic epidermal necrolysis. Therefore, the nurse should instruct the client to promptly report any signs of skin rash or other skin changes.

D. Metallic taste:

Metallic taste is a common side effect of phenytoin. While it is not usually a serious adverse effect, it can be bothersome for some individuals. Therefore, the nurse should instruct the client to monitor for this side effect and report it if it occurs persistently or becomes bothersome.

A. "I will notify my provider before taking any other medications."

This statement demonstrates understanding of the importance of consulting the provider before taking any other medications. It is correct because phenytoin may interact with other drugs, so notifying the provider is essential to avoid potential interactions.

B. "I have made an appointment to see my dentist next week."

This statement indicates that the client understands the importance of dental care while taking phenytoin. Phenytoin can cause gum overgrowth (gingival hyperplasia), so regular dental check-ups are recommended to monitor oral health. This statement is correct.

C. "I will take this medication with meals."

This statement suggests that the client plans to take phenytoin with meals. However, phenytoin should generally be taken on an empty stomach to enhance absorption, unless gastrointestinal upset occurs. Therefore, this statement indicates a need for further teaching.

D. "I'll be glad when my seizures stop so I can quit taking this medicine."

This statement reflects a misconception about the management of epilepsy. Phenytoin is typically used as a long-term treatment to prevent seizures, not as a short-term solution to stop seizures. Therefore, this statement indicates a need for further education about the chronic nature of epilepsy and the need for ongoing medication adherence.

E. “I’ll take this medication before meals.”

This statement correctly indicates the timing of phenytoin administration before meals. Taking phenytoin before meals helps enhance absorption and minimize the risk of gastrointestinal side effects. Therefore, this statement is correct.
