A client with irritable bowel syndrome starts a new prescription for dicyclomine, an anticholinergic medication. The client reports the onset of sensitivity to bright sunlight and a dry mouth. How should the nurse respond?

Choice A reason: Although breastfeeding is not recommended while taking isotretinoin due to the potential for serious side effects, the most critical concern for a client planning to become pregnant is the teratogenic effects of the drug.

Choice B reason: While avoiding additional vitamin A is important to prevent toxicity, the priority for a client planning to conceive is to avoid the teratogenic effects of isotretinoin.

Choice C reason: Discontinuing isotretinoin one month before attempting to conceive is crucial because the drug is highly teratogenic and can cause severe birth defects. Ensuring the medication is out of the client's system before conception is the most important step to prevent harm to the fetus.

Choice D reason: Baseline liver function results are important for monitoring therapy, but they do not address the critical issue of preventing teratogenic effects in a client planning to become pregnant.

Choice A reason: Feverfew can interact with aspirin or NSAIDs, potentially increasing the risk of bleeding. This information is crucial for clients to avoid adverse interactions.

Choice B reason: While increased anxiety and nervousness have been reported, these side effects are less critical compared to the potential for harmful drug interactions.

Choice C reason: Those with allergies to chamomile, ragweed, or yarrow should avoid feverfew, but the primary concern should be potential drug interactions.

Choice D reason: Gastrointestinal side effects such as abdominal pain, gas, nausea, vomiting, and diarrhea are important to note, but they do not pose as immediate a risk as the potential for drug interactions.
