Which client statement requires further teaching regarding oxybutynin for overactive bladder?

The statement indicating a "looking forward to our summer vacation at the beach" suggests a lack of understanding about a possible side effect of oxybutynin, which can cause heat-related issues. Oxybutynin is an anticholinergic medication often prescribed for overactive bladder, and it can reduce sweat production, increasing the risk of heat illness, especially in warm environments. Patients taking this medication should be advised to take precautions in hot weather, such as staying hydrated and avoiding prolonged exposure to heat, particularly during activities like a beach vacation where high temperatures and sun exposure are common.

In contrast, planning to eat more fruits and vegetables to prevent constipation shows good understanding since oxybutynin can cause constipation as a side effect. Acknowledging the need to avoid driving until the effects of the medication are clear reflects the cautious approach needed when starting any new medication that might impair coordination or alertness. Furthermore, committing to drinking adequate water supports hydration, which is particularly important given the potential for reduced sweating and the risk of heat-related complications when taking oxybutynin.
