An 11-year-old client has been diagnosed with epilepsy and prescribed phenytoin 100 mg PO b.l.d. What statement by the client's parent suggests an accurate understanding of the client's medication regimen?

A. “I will make sure my child takes the medication on an empty stomach": Phenytoin can be taken with or without food, but taking it with food helps reduce gastrointestinal upset. Timing with food is less critical than ensuring consistent daily dosing for stable blood levels. B. "I will stop the drug immediately if any side effects occur.": Abruptly stopping phenytoin can trigger rebound seizures or status epilepticus. Any side effects should be reported to the healthcare provider, but discontinuation must be done under medical supervision. C. "I will make sure my child has routine visits to the dentist.": Phenytoin can cause gingival hyperplasia, particularly in children. Regular dental check-ups and good oral hygiene are essential to monitor and manage this common side effect. D. “I will weigh my child daily and feed them a high-calorie diet.": Daily weighing and a high-calorie diet are unnecessary unless there are other medical conditions affecting weight or nutrition. Phenytoin does not require such dietary monitoring.
