, - Stool impaction is the development of a solid immobile mass of fecal matter in the

rectum, which may result in liquid stool. Therefore the nurse should assess for this first.

An enema helps to facilitate bowel movements but should be avoided because it

increases the intracranial pressure. Psyllium is a form of fiber used to increase the solid

mass in the intestine so that the feces can pass easily. Physical activity stimulates bowel

function, so the nurse should encourage the patient to perform physical activity.
