A nurse is caring for a client who has an acute exacerbation of chronic pain. Which of the following medications should the nurse anticipate administering for the client?

Rationale:

A. "Biofeedback requires concentration to control physiological responses.": Biofeedback is a technique that helps clients gain voluntary control over involuntary bodily functions, such as muscle tension, heart rate, or skin temperature. Through focused concentration and real-time feedback from monitoring devices, clients learn to reduce stress and prevent migraine triggers.

B. “Biofeedback improves energy flow through soft tissue manipulation to increase circulation.": This description aligns more with massage or energy-based therapies, not biofeedback. Biofeedback does not involve physical manipulation of tissues but relies on monitoring and controlling physiological responses through mental focus.

C. "Biofeedback uses herbs to reduce inflammation": Herbal therapy is a complementary approach unrelated to biofeedback. Biofeedback does not incorporate herbal remedies and instead emphasizes self-regulation techniques using bio-monitoring equipment.

D. “Biofeedback stimulates certain pressure points to relax muscles": Stimulating pressure points is characteristic of acupressure or acupuncture, not biofeedback. While muscle relaxation is a goal of biofeedback, it is achieved through self-regulation and feedback, not external stimulation.

Rationale:

A. "Using this machine increases my risk of overdose.": PCA pumps are designed with safety features, including dose limits and lockout intervals, which reduce the risk of overdose. Understanding this helps the client recognize that PCA is a safe method for self-administered pain control when used correctly.

B. “I can get pain medication any time as long as I press the button”: The client can only receive medication according to the programmed dose and lockout interval. Pressing the button repeatedly will not override the safety mechanism, so this reflects a misunderstanding of how PCA pumps function.

C. "My partner can press my pain medication button for me if I am sleeping": PCA pumps are intended for self-administration only. Allowing someone else to press the button (a practice called “PCA by proxy”) can cause overdose and is unsafe, especially if the client is sleeping or sedated.

D. "I will receive a limited amount of pain medication when I press the button.": PCA pumps deliver a preset dose with a lockout interval to prevent overdose. This statement shows the client understands the safety mechanisms in place, indicating correct comprehension of PCA use.
