A client with residual arm pain after a fall asks how acupuncture is supposed to help. What is the best nurse's response?

• A. Acupuncture works by cooling the area.
• B. Pain relief comes only from medication.
• C. Acupuncture is unsafe and should be avoided.
• D. Pain is relieved by releasing endorphins, which balance the flow of energy.

Answer: (D)

The main idea is that acupuncture can reduce pain by activating the body's own pain-control system, specifically by triggering the release of endorphins. When needles are inserted or stimulated, nerves send signals to the brain and spinal cord that kick off the production of endogenous opioids like endorphins. These natural chemicals dampen pain signals and create a sense of relief, which can help with residual arm pain after a fall.

That mechanism fits the Nursing perspective well: it explains a plausible, non-drug way to lessen pain and can complement other treatments. The phrase about balancing energy reflects traditional explanations, but the physiological basis—endorphin release and modulation of pain pathways—provides a clear, evidence-aligned reason why acupuncture can help.

It’s not accurate to say it works by cooling the area, nor that pain relief comes only from medications, and while safety depends on the practitioner, acupuncture is not inherently unsafe when done by a trained professional.
