What is the highest temperature up to which fluid can be heated for peritoneal lavage in a hypothermic client?

For peritoneal lavage in a hypothermic client, the ideal temperature for the fluid needs to be warm enough to help raise the client's body temperature without causing any thermal injury to the peritoneal cavity. The correct answer indicates that the maximum fluid temperature permissible for this procedure is 113°F (45°C).

This temperature is effective because it is warm enough to promote rewarming of the body, enhancing thermoregulation while still being within safe limits for internal use. Fluid heated above this temperature can potentially lead to complications, including damage to the peritoneal lining, which can cause irritation or inflammation.

Maintaining the fluid temperature at this level provides a balance between effectiveness in raising the client's core temperature and ensuring patient safety during the procedure. The other options present higher temperatures that pose greater risks for thermal injuries without additional benefits in therapeutic effect.
