A nurse is planning to complete dressing changes for an adolescent who has multiple burn injuries. Which of the following interventions addresses the greatest risk to the client?

A. Check the wound sites for manifestations of infection: Monitoring for infection is important in burn care, but immediate life-threatening complications include fluid and heat loss. Infection usually develops later, making it a serious but not the greatest immediate risk during dressing changes. B. Perform passive range-of-motion exercises during the dressing change: Passive range-of-motion helps prevent contractures and maintain mobility, which is important for long-term recovery, but it does not address the most urgent risk to the client during burn care. C. Adjust the room temperature to 33° C (91.4° F): Children and adolescents with multiple burns are at high risk for hypothermia due to impaired thermoregulation and extensive loss of skin. Maintaining a warm environment is crucial during dressing changes to prevent dangerous drops in core body temperature. D. Apply tepid water to the old dressings before removal: Moistening the dressings helps reduce pain and prevent further tissue trauma, but it does not directly address the greatest immediate physiological risk, which is hypothermia in burn patients.
