What statement shows that a client understands the instructions for taking phenytoin?

A statement indicating that good oral hygiene is needed, including brushing and flossing, demonstrates a clear understanding of the instructions for taking phenytoin. Phenytoin is known to cause gingival hyperplasia, a condition where the gums become overgrown or swollen, leading to an increased risk of gum disease and dental issues. Therefore, maintaining proper oral hygiene is crucial for patients on this medication to help mitigate these side effects and promote overall oral health. This understanding reflects the patient’s awareness of the importance of self-care measures while managing their treatment.

In contrast, the other choices reflect misunderstandings about medication adherence and health management while on phenytoin. Stopping medication prematurely might lead to seizure recurrence, skipping follow-up appointments could hinder monitoring for side effects or drug levels, and taking over-the-counter pain relievers may pose risks of interactions or side effects that the patient needs to be aware of.
