Which potential drawback must a nurse consider when advising a CAM therapy such as acupuncture?

Rationale: A. Many complementary and alternative medicine (CAM) therapies, including acupuncture, may have promising results, but the evidence supporting their effectiveness is often limited or inconsistent. Nurses must consider this limitation when advising patients, ensuring they provide accurate information and integrate CAM safely with conventional treatments. B. CAM therapies are generally used as adjuncts to conventional medicine, not as complete replacements. Advising that acupuncture or other CAM treatments can replace essential medical care would be unsafe and misleading. C. CAM therapies, including acupuncture, do not guarantee relief for all patients or conditions. Outcomes vary based on the individual, condition, and practitioner skill. Making such claims would be inaccurate and potentially dangerous. D. Acupuncture and similar CAM therapies are generally low-risk when performed by trained practitioners. While minor side effects such as bruising, soreness, or mild bleeding can occur, catastrophic reactions are extremely rare. The main concern is effectiveness and evidence, not high-risk immediate complications.
