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 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.

Choice A rationale:
Increasing pain over several hours is not a typical sign of a fentanyl patch overdose. Fentanyl is a potent opioid, and overdose symptoms often involve respiratory depression, altered mental status, and other serious issues. While it is possible for a patient to experience increased pain if the fentanyl patch is not providing adequate pain relief, this is not a specific sign of overdose.
Choice B rationale:
An itchy red rash on the skin is not a sign of a fentanyl patch overdose but can be associated with skin irritation or allergies to the adhesive in the patch. It's important to differentiate between a skin reaction and an overdose when evaluating patients using fentanyl patches. Overdose symptoms are more severe and life-threatening.
Choice C rationale:
Confusion and the inability to walk normally are characteristic signs of a fentanyl patch overdose. Fentanyl is a potent opioid, and overdose can lead to central nervous system depression, resulting in confusion, altered mental status, and difficulty with coordination and walking. These symptoms are serious and require immediate medical attention.
Choice D rationale:
Headache and nausea are not specific signs of a fentanyl patch overdose. While opioid overdose can cause various symptoms, such as respiratory depression and altered mental status, headache and nausea are not among the primary indicators. However, individual responses to medications can vary, and some patients may experience these symptoms as part of a broader set of overdose signs.
