Kayexalate binds to and helps excrete potassium, so it would be contraindicated in patients who are hypokalemic (have low potassium). Normal saline enemas can be repeated without risk of fluid or electrolyte imbalance. Hypertonic solutions are intended for patients who cannot handle large fluid volume and are contraindicated for dehydrated patients. Oil retention enemas lubricate the feces in the rectum and colon and are used for constipation.

ANS: D
The patient with chronic constipation or fecal incontinence secondary to cognitive impairment may benefit from bowel training, also called habit training.
