The nurse knows that many medications given to clients have predictable, secondary effects which may be harmful or may be beneficial. The nurse always includes these effects in client teaching.

B. Activating a code blue or the facility's emergency response system will bring immediate assistance and resources to the client's bedside. This is crucial to initiate prompt resuscitative measures if indicated and to involve additional healthcare providers in the management of the emergency.

A. While it might be appropriate in some situations to provide privacy or support to the partner, in this urgent scenario where the client is unresponsive and not breathing, the priority should be immediate assessment and intervention for the client's condition.

C. While notifying the physician is important, especially to inform them of the client's condition and potentially discuss the DNR status, it is not the most immediate action in this urgent situation where the client is unresponsive and not breathing. Direct intervention and assessment are needed first.

D. Asking the partner to make a DNR decision immediately is not appropriate as the first action in this scenario. It is crucial to focus first on the client's immediate needs for assessment and potentially resuscitative measures if indicated. The discussion about the DNR order should occur in a timely manner but is secondary to addressing the client's current medical emergency.

B. Temperature can significantly affect sleep quality. Ensuring the room is kept at a comfortable temperature (not too hot or cold) can promote better sleep. This intervention is appropriate.

C. Clean and dry bed linens contribute to comfort, which is essential for promoting sleep. This intervention is appropriate.

D. Discomfort can be a major barrier to sleep. Addressing any discomfort, such as pain, anxiety, or positioning issues, can help improve the client's ability to fall and stay asleep. This intervention is appropriate.

A. Offering chocolate, which contains caffeine, close to bedtime is not recommended as caffeine can interfere with sleep. Therefore, this option is not appropriate.

E. Moving the client closer to the nursing station may increase noise and disrupt sleep, especially if there are frequent activities or conversations near the nursing station. Therefore, this option is not typically recommended unless the client requires closer monitoring due to medical reasons.
