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. Determining weight loss can be useful but does not directly address the sleep issue the client is experiencing. B. While it’s true that lifestyle changes can take time to show effects, this response does not help the client understand or address their sleep difficulties. C. Encouraging daily exercise is beneficial but may not be appropriate if the client is already exercising; quality and timing of exercise should also be considered. D. Asking for a description of the exercise schedule can help the nurse assess the type and timing of exercise, which may be relevant to the client's sleep problems.
