A client is facing stress-induced insomnia after starting atypical antipsychotics. Which intervention should the nurse suggest to improve sleep?

Choice A reason: While regular physical exercise is generally beneficial for long-term sleep hygiene, joining a structured class may increase the client's stress level if they are already overwhelmed. Furthermore, vigorous exercise performed too close to bedtime can actually act as a stimulant, making it harder for the client to fall asleep. Choice B reason: Teaching breathing techniques is a valuable coping mechanism for anxiety; however, performing them in the morning provides no direct physiological benefit for evening sleep onset. For an intervention to address insomnia effectively, it must be applied during the period immediately preceding the desired sleep cycle. Choice C reason: Avoiding caffeine during dinner is a standard sleep hygiene recommendation, but it is often insufficient for "stress-induced" insomnia. While reducing stimulants is helpful, it does not actively address the sympathetic nervous system overactivity that prevents the client from transitioning into a restful state at night. Choice D reason: Progressive relaxation involves systematically tensing and releasing muscle groups, which directly counteracts the physiological manifestations of stress. By implementing this specific technique immediately before bedtime, the client can lower their heart rate and cortisol levels, facilitating the transition into sleep despite the effects of medication.
