What is the purpose of a cleansing enema?

  1. To assess rectal temperature

  2. To clean the bowel of feces and flatus

  3. To hydrate the body

  4. To prevent dehydration

The correct answer is: To clean the bowel of feces and flatus

A cleansing enema is used to remove feces and gas from the large intestine in order to clean the bowel. Option A, assessing rectal temperature, is not the purpose of a cleansing enema and can be done without administering an enema. Option C, hydrating the body, is also not the purpose of a cleansing enema, as the primary function is to remove waste from the bowel. Option D, preventing dehydration, is not the purpose of a cleansing enema, although it may be a beneficial side effect.
