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. Abdominal aortic aneurysm: While this condition is serious, it does not directly affect the safety of applying localized heat therapy to a distal site like the foot, unless systemic complications are present. B. Osteoarthritis: Heat therapy is often beneficial in osteoarthritis, as it helps reduce joint stiffness and improve circulation to the affected area, making it a common and safe intervention. C. Phlebitis: Warm compresses are sometimes used in phlebitis to reduce inflammation and promote comfort, provided there are no signs of infection or severe vascular compromise. D. Peripheral neuropathy: Clients with peripheral neuropathy have impaired sensation and may not feel excessive heat, increasing the risk of burns or tissue injury. This makes heat therapy unsafe for these individuals.
