Ondansetron (Zofran) has been ordered for the patient undergoing cancer chemotherapy to control the severe nausea and vomiting. What side effects should the nurse observe for?

A. "You will need to take an anticonvulsant of some type for your lifetime."

This statement may be accurate for some individuals with chronic or recurrent seizure disorders, but it is a generalization. The duration of anticonvulsant therapy varies from person to person, and some individuals may eventually be able to discontinue medication under the guidance of their healthcare provider.

B. "This medication should be taken until you haven't had a seizure for a month."

While seizure control is a factor in determining the duration of treatment, setting a specific timeframe (e.g., one month) may not be applicable to everyone. The decision to continue or discontinue anticonvulsant therapy is usually individualized and based on various factors, including the type of seizure disorder and the individual's response to treatment.

C. "Seizures are unpredictable and so is the duration of the treatment."

This is the best response. It acknowledges the variability in seizure disorders and the individualized nature of treatment duration. Seizure management is often an ongoing process that requires monitoring and adjustments based on the person's specific circumstances.

D. "You will only need to take it for a short period of time because anticonvulsants will cure the seizure disorder."

Anticonvulsants are typically used to manage and control seizures rather than cure the underlying seizure disorder. While some individuals may experience a period of seizure freedom and be able to discontinue medication, this is not true for everyone. The duration of treatment varies, and some individuals may require long-term or even lifelong therapy.

A. "Continue taking OCPS because phenytoin is not safe during pregnancy."

This statement is not accurate. While it's essential to address pregnancy risk, phenytoin can reduce the effectiveness of oral contraceptives. Women on phenytoin are often advised to use additional contraceptive measures.

B. "You should use a backup method of contraception along with OCPs."

This is the correct response. Phenytoin can accelerate the metabolism of oral contraceptives, potentially reducing their effectiveness. Using a backup method, such as condoms, is recommended to ensure adequate contraception.

C. "You should stop taking OCPs because of drug-drug interactions with phenytoin."

This advice is generally not recommended without consulting the healthcare provider. Abruptly stopping OCPs without an alternative form of contraception can increase the risk of unintended pregnancy.

D. "You should take low-dose aspirin while taking these medications to reduce your risk of stroke."

This statement is not relevant to the situation described. Low-dose aspirin is not typically recommended for contraception, and its use in this context does not address the potential interaction between phenytoin and oral contraceptives.
