A nurse is reviewing the medical record of a client who has a prescription for intermittent heat therapy for a foot injury. Which of the following findings should the nurse identify as a contraindication for heat therapy?

A. Phlebitis: Localized heat can actually help improve circulation and reduce discomfort in mild cases of phlebitis, so it is not an absolute contraindication. Heat therapy may be used cautiously depending on the severity and location. B. Abdominal aortic aneurysm: Heat therapy applied to areas away from the aneurysm site is generally safe. There is no direct contraindication unless heat is applied over the aneurysm, which could increase local blood flow and risk. C. Osteoarthritis: Heat therapy is commonly used to relieve joint stiffness and muscle spasms in osteoarthritis. Applying intermittent heat can improve comfort and mobility without causing harm. D. Peripheral neuropathy: Clients with peripheral neuropathy have impaired sensation and may not perceive excessive heat, increasing the risk of burns or tissue injury. Therefore, impaired sensation is a contraindication for heat therapy to prevent thermal injury.
