A nurse is caring for a client who is receiving chemotherapy and requests information about acupuncture to relieve some of the side effects. Which of the following findings should the nurse identify as a contraindication to receiving this alternative therapy?

Nursing care for clients receiving chemotherapy often includes supporting complementary therapies that may help manage treatment-related side effects such as nausea, fatigue, and pain. However, safety considerations are essential when recommending alternative therapies like acupuncture, especially in immunocompromised clients. Acupuncture involves skin penetration, which increases the risk of infection, bleeding, and impaired tissue healing. Certain conditions require caution or avoidance due to increased risk of complications. Rationale: A. Mouth sores (oral mucositis) are a common side effect of chemotherapy but are not a contraindication to acupuncture. While uncomfortable, they do not directly increase risks associated with needle insertion at peripheral body sites. Acupuncture may even be used to help manage chemotherapy-related symptoms such as nausea and pain. B. Headaches are not a contraindication to acupuncture because it is commonly used as a complementary therapy for headache relief, including tension-type and migraine headaches. There is no direct risk that headaches pose to the safety of acupuncture treatment. Instead, acupuncture may be beneficial in reducing headache frequency and intensity. C. Urticaria (hives) is a skin manifestation of allergic reaction but is not an absolute contraindication to acupuncture. However, active skin irritation or lesions at needle insertion sites may require caution. The presence of urticaria does not inherently increase the risk of systemic complications from acupuncture. D. Lymphedema is a contraindication because acupuncture involves skin puncture, which can increase the risk of infection in an area with impaired lymphatic drainage. In clients with lymphedema, especially post-cancer treatment, there is already reduced immune surveillance in the affected limb. Needle insertion can introduce pathogens and worsen swelling or lead to serious complications such as cellulitis.
