A 25 year-old female patient will begin taking phenytoin for epilepsy. The patient tells the nurse she is taking oral contraceptives (OCPs). Which response will the nurse give?

A. Bradycardia

Bradycardia is not a common side effect of diphenoxylate with atropine. Atropine, which is included in the combination, has anticholinergic effects that can lead to an increased heart rate (tachycardia), not bradycardia.

B. Fluid retention

Fluid retention is not a common side effect of diphenoxylate with atropine. In fact, the medication is used to treat severe diarrhea, and the goal is to decrease fluid loss associated with diarrhea rather than causing fluid retention.

C. Nervousness and tremors

Nervousness and tremors are not common side effects of diphenoxylate with atropine. Atropine's anticholinergic effects may cause nervousness, but these effects are generally not prominent at therapeutic doses.

D. Respiratory depression

This is the correct choice. Respiratory depression is a potential side effect of diphenoxylate with atropine, particularly if the medication is misused or taken in excessive amounts. Atropine is included in the combination to discourage misuse, as it can cause unpleasant anticholinergic effects.

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.
