What is the main action of an oil retention enema?

  1. Hydrates the body

  2. Irritates the rectum

  3. Lubricates the rectum and softens feces

  4. Promotes blood circulation

The correct answer is: Lubricates the rectum and softens feces

An oil retention enema is a method used to help relieve constipation by inserting a small amount of oil into the rectum. This oil helps to lubricate the rectum and soften any hardened feces, making it easier to pass. Option A is incorrect because while the enema may increase hydration levels temporarily, its main purpose is not to hydrate the body. Option B is incorrect because the enema should not cause irritation, and if it does, it is likely being done incorrectly. Option D is incorrect because the main action of an oil retention enema is not to promote blood circulation, although it may have some beneficial effects on circulation.
