A nurse evaluating the effectiveness of an Aquathermia K pad for the leg is aware that the patient who has the least risk for burn injury from this device would be the patient with:.

Choice C rationale:
Keeping a night light on in the room is the most helpful intervention for a child having difficulty falling asleep. Night lights provide a comforting and soothing environment, reducing the fear of the dark and making the child feel secure. It also helps prevent complete darkness, which can be particularly helpful for children who may be afraid of the dark. This intervention promotes a positive sleep environment and can facilitate the child's ability to fall asleep.
Choice A rationale:
Giving juice and cookies before bedtime is not an appropriate intervention to help a child fall asleep. In fact, providing sugary snacks before bedtime can lead to increased activity and may make it even more challenging for the child to sleep.
Choice B rationale:
Having the parents bring a favorite blanket or pillow from home is a nice gesture and can provide comfort to the child, but it may not directly address the issue of falling asleep. While it can be part of creating a familiar and comforting sleep environment, it may not be sufficient on its own to help the child fall asleep.
Choice D rationale:
Turning off all the lights in the room may not be the best approach, as complete darkness can be frightening for some children. It's important to strike a balance between creating a soothing sleep environment and avoiding overwhelming darkness, which is why keeping a night light on is often a better option.

Choice A rationale:

This statement is not accurate and may confuse the client. In a Patient-Controlled Analgesia (PCA) system, a predetermined dose is delivered when the patient activates the device. The dose is usually controlled to prevent excessive medication administration.

Choice B rationale:

This statement is correct. The essence of PCA is that the patient has control over administering their pain medication within set limits or time intervals. The patient can self-administer doses when needed, ensuring effective pain management.

Choice C rationale:

Allowing the partner to push the PCA button for the patient is not recommended. PCA systems are designed to be controlled by the patient themselves to prevent potential overdosing. Involving someone else in the administration can lead to safety concerns.

Choice D rationale:

PCA systems do not deliver medication into the muscle. They typically deliver medication intravenously (IV) or subcutaneously. This statement is inaccurate and could lead to misconceptions about how the PCA system works.
