What statement by a client indicates understanding of instructions regarding phenytoin administration?

The statement indicating an understanding of instructions regarding phenytoin administration is about using a soft toothbrush to brush teeth. Phenytoin, an antiepileptic medication, can lead to gum overgrowth, which is a common side effect. Therefore, using a soft toothbrush can help minimize trauma to the gums and reduce the risk of bleeding or further irritation. This understanding is crucial for maintaining oral hygiene and managing the side effects of the medication effectively.

The other statements demonstrate misunderstandings of important aspects of phenytoin treatment. Taking the medication with food is not typically required and may affect absorption. Stopping the medication when feeling better can lead to seizure recurrence and should only be done under a doctor's guidance. Finally, regular follow-up with a healthcare provider is essential to monitor therapeutic levels and side effects, emphasizing the importance of ongoing medical supervision while on phenytoin.
