A nurse in a provider's office is caring for a client who asks about using acupuncture to manage his osteoarthritis pain. The nurse should identify which of the following conditions as a contraindication for receiving this treatment?

A. Acupuncture involves inserting needles into the skin, which can introduce infections. Herpes zoster (shingles) causes skin lesions and nerve pain, making acupuncture unsafe due to the risk of exacerbating the condition or spreading the virus. B. Hypothyroidism does not affect the safety of acupuncture. C. Obesity is not a contraindication but may require adjustments in acupuncture techniques. D. Hypertension is not a contraindication unless the client has severe, uncontrolled hypertension.
