A hospitalized client has had difficulty falling asleep for two nights and is becoming irritable and restless. Which action by the nurse is best?

By determining the client's usual bedtime routine and incorporating these rituals into the care plan, the nurse can help the client fall asleep faster and improve the quality of care without compromising safety. This approach respects the client's individual needs and preferences. In contrast, options B, C, and D do not address the client's sleep issue effectively and may even compromise the client's safety or standard of care. Option B fails to address the underlying problem of the client's sleep disturbance, while option C reduces the frequency of assessments, which can impact the timely identification of changes in the client's condition. Option D focuses on pain medication and daytime napping, which are not directly related to the client's current sleep difficulties.
