Bowel and Urinary Elimination, Catheters and Ostomies

Supporting Bowel Elimination and Managing Alterations

Normal bowel elimination frequency in healthy adults ranges from three times a day to three times a week. The practical nurse reinforces teaching that regular physical activity, adequate fluid intake, and dietary fiber work together to promote regular bowel movements. When clients need pharmacological support, safety guidelines protect the digestive tract. Bulk-forming laxatives require adequate water, commonly at least 8 ounces, to reduce the risk of obstruction; if the client has a fluid restriction or difficulty swallowing, consult the registered nurse before administration. When an oil-retention enema is administered, the client should retain the fluid for at least 30 minutes to soften hard stool prior to evacuation.

Administering an enema requires specific positioning and careful technique to ensure comfort and safety. The preferred position for enema administration is the left Sims position to facilitate fluid flow along the natural curve of the sigmoid colon. For an adult client, the practical nurse lubricates the rectal tube and inserts it 3 to 4 inches toward the direction of the umbilicus. The fluid container should be held about 12 to 18 inches above the anus, as excessive height can cause rapid flow and cramping. If the client reports abdominal cramping during the infusion, the practical nurse temporarily clamps the tubing or lowers the container until cramping subsides before continuing.

Severe constipation can progress to a bowel blockage that requires immediate intervention. Continuous oozing or passing of small amounts of liquid stool in a constipated client suggests a fecal impaction. If digital disimpaction is ordered and permitted by state scope and facility policy, the practical nurse carefully monitors the client's pulse because vagal stimulation during the procedure can cause bradycardia. If the client develops bradycardia, diaphoresis, or lightheadedness, the practical nurse stops the procedure immediately and notifies the registered nurse.
