A nurse is caring for a client who has Wernicke-Korsakoff psychosis as a result of chronic alcohol use disorder. Which of the following interventions should the nurse anticipate?

A. "I'll be glad when I can stop taking this medicine.": This statement indicates a misunderstanding about phenytoin therapy. Phenytoin is typically a long-term medication used to prevent seizures, and it is not typically discontinued unless under the guidance of a healthcare provider. The nurse should clarify that stopping the medication abruptly can lead to rebound seizures and should emphasize the importance of continuing the medication as prescribed.

B. "I have made an appointment to see my dentist next week.": This statement indicates appropriate understanding, as regular dental check-ups are important for individuals taking phenytoin due to the medication's potential side effect of gingival hyperplasia.

C. "I know that I cannot switch brands of this medication.": This statement demonstrates understanding, as different brands of phenytoin can have variations in bioavailability, which can affect seizure control. It is important for clients to remain consistent with the same brand or formulation unless directed otherwise by their healthcare provider.

D. "I will notify my doctor before taking any other medications.": This statement indicates understanding of the potential for drug interactions with phenytoin, as it is a hepatic enzyme inducer and can affect the metabolism of other medications. Clients should always consult their healthcare provider before taking any new medications or supplements to ensure compatibility with phenytoin therapy.

A. "He has so many new bruises on his body."

This statement raises concerns about potential adverse effects of carbamazepine, such as hematologic effects like thrombocytopenia, which could manifest as bruising. Given the potential seriousness of this issue, it should be the nurse's priority to further assess and address.

B. "He says his mouth is always dry."

Dry mouth (xerostomia) is a common side effect of carbamazepine, but it is generally not as concerning as other potential adverse effects such as hematologic issues or liver toxicity.

C. "He says he feels sick to his stomach after taking this medication."

Gastrointestinal side effects, including nausea, are common with carbamazepine but are typically not as urgent or serious as other potential adverse effects.

D. "He takes a 2-hour nap every day after school."

While changes in sleep patterns can be important to monitor, especially in adolescents, it is not as urgent as addressing potential adverse effects such as bruising.
