What is the main action of an oil retention enema?

Hydrates the body
Irritates the rectum
Lubricates the rectum and softens feces
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.
