The nurse recognizes that which of the following items affect the client's physiological tolerance to heat and cold?
Select all that apply.
1. Body part
2. Race and ethnic origin
3. Size of the exposed body part
4. Intactness of the skin
5. Length of exposure
Correct Answer: 1,3,4,5
Some body parts, such as the back of the hand or foot, are not temperature-sensitive, whereas other areas, such as the wrist and neck, are more temperature-sensitive. The larger the area exposed to heat and cold, the lower the tolerance. People feel hot and cold application most while the temperature is changing, and then tolerance increases, so length of exposure is a factor. Injured skin, or skin that is not intact, is more temperature-sensitive. Race and ethnic background are not factors influencing temperature tolerance.
