A client tells the nurse about beginning an exercise program a month ago to lose weight and improve sleep. The client states, "It still takes at least two hours to fall asleep at night." Which action should the nurse implement?

A. Understanding the exercise schedule can help the nurse determine if the timing or type of exercise is contributing to sleep issues. B. Exercising every day can be beneficial, but the timing of exercise (e.g., too close to bedtime) can impact sleep. C. While lifestyle changes do take time, the nurse should first assess the current exercise habits to provide tailored advice. D. Weight loss is an important outcome but does not directly address the sleep issue.
