The nurse applies an aquathermia heat pack to the client's right leg and removes it after no more than 45 minutes. What is the nurse trying to avoid by completing this action?
1. Vasodilation
2. Rebound phenomenon
3. Heat tolerance
4. Systemic effects
Correct Answer: 2
A rebound phenomenon occurs at the time the maximum therapeutic effect is achieved and the opposite effects begin, and can result in a burn. Vasodilation is the desired effect of heat. Heat tolerance begins shortly after applying the heat pack as the skin adapts to the warmth. Systemic effects will occur when heat is applied to a large localized area of the body, increasing cardiac output and pulmonary ventilation.
