Going to bed hungry or overly full does not interfere with sleep.

It helps the patient reach REM state of sleep faster.

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:
The primary care provider (PCP) is responsible for prescribing the PCA but does not typically program the PCA pump. The PCP may set the initial parameters for the PCA, such as the dose and lockout interval, but the actual programming and operation of the PCA pump is typically carried out by the nursing staff.
Choice B rationale:
Pharmaceutical companies manufacture and provide medications, including the medications used in PCA, but they do not program PCA pumps. Programming and administration of the PCA are nursing responsibilities.
Choice D rationale:
Licensed Practical Nurses (LPN) or Licensed Vocational Nurses (LVN) can assist in the administration and monitoring of PCA, but they do not typically program the PCA pump. Registered nurses are usually responsible for the programming and operation of PCA pumps.
