Evolve HESI Practice Exam

How should the nurse respond to a client stating that they feel cold after an extended period of heat application?

1. Offer a blanket

2. Explain thermal adaptation

3. Lower the heating pad's temperature

4. Change the application site

The correct answer is: Explain thermal adaptation

The appropriate response to a client feeling cold after extended heat application is to explain thermal adaptation. When heat is applied to the body for a prolonged period, the initial sensation of warmth can give way to a feeling of coldness as the body adapts to the temperature increase. This phenomenon occurs because the blood vessels dilate, and blood flow increases to the area being treated, which can lead to a feeling of cold once the heat source is removed or if the body reaches a stable temperature with the heat applied. Thermal adaptation helps the patient understand that their sensations are a normal physiological response rather than a reason for concern. By educating the client about this process, the nurse fosters an understanding of their body's responses to heat therapy, thus improving the overall therapeutic experience. While offering a blanket could address the sensation of being cold, it does not help the client understand their bodily response. Lowering the heating pad's temperature may not address the cause of the feeling they are experiencing, and changing the application site might disrupt the treatment without addressing the client's concerns.
