A nurse is reinforcing teaching with a female client who is taking phenytoin. Which of the following statements should the nurse include in the teaching?

Phenytoin is known to cause gingival hyperplasia, which is characterized by swollen and enlarged gums. This side effect is more common in long-term use and may require dental care and regular oral hygiene practices. Phenytoin is known to be associated with an increased risk of birth defects in babies born to women taking the medication during pregnancy. It is important for women of childbearing age to discuss the risks and benefits of phenytoin with their healthcare provider and use effective contraception to avoid pregnancy while taking the medication. Phenytoin can affect liver function, so regular monitoring of liver enzymes and blood levels of the medication is necessary. The frequency of blood work may vary depending on the individual's specific situation, so it is important to follow the healthcare provider's instructions. It is not advisable to skip a dose of phenytoin without consulting a healthcare provider. Abruptly stopping or missing doses of antiepileptic medications can lead to breakthrough seizures or other complications. Any changes in the medication regimen should be discussed with the healthcare provider.
