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:

A patient with a decreased level of consciousness from a stroke may not be able to provide feedback or recognize discomfort or pain, which can increase the risk of burn injury when using a heating pad. This choice increases the risk rather than reducing it.

Choice B rationale:

A patient with neuritis secondary to diabetes has a decreased sensitivity in the affected area due to nerve damage. While this can be a challenging condition, it reduces the patient's ability to perceive heat and pain, making them less likely to realize if the heating pad becomes too hot. As a result, this patient has the least risk for burn injury when using the Aquathermia K pad.

Choice C rationale:

A severely sprained ankle is not related to the risk of burn injury from a heating pad. This choice is not relevant to the assessment of burn injury risk with the Aquathermia K pad.

Choice D rationale:

Impaired peripheral circulation can increase the risk of burn injury from a heating pad. Patients with compromised circulation have a reduced ability to dissipate heat, which can lead to localized overheating and potential burn injury. This choice increases the risk of injury. .
