The nurse is assessing a patient who reports bleeding during defecation. the nurse asks the patient to do the valsalva maneuver and sees a red mucosal mass inside the anus. what could be the cause of this condition in the patient?

In rectal prolapse, the rectal mucous membrane projects through the anus, giving the impression of a moist red doughnut with glowing lines. It arises following a Valsalva maneuver, such as straining at stool, or with exercise. These symptoms are reliable with an external hemorrhoid. An external hemorrhoid comprises clotted blood and becomes a throbbing, inflamed, shiny blue mass that itches and exploits with excretion.
