A client had a perforated diverticulum and has undergone a bowel diversion called a Hartmann's procedure. The nurse knows the purpose of a Hartmann's procedure is to:

Hartmann's procedure involves the surgical resection of the diseased rectosigmoid colon with the creation of a terminal colostomy and a distal non-functional rectal stump. It is primarily indicated for emergency management of perforated diverticulitis or obstructing sigmoid malignancies where primary anastomosis is hazardous. This temporary diversion mitigates the risk of anastomotic leakage and fecal peritonitis in an acutely inflamed pelvis. A. allow for more thorough irrigation.: Irrigation is a mechanical management technique for established colostomies to regulate bowel movements and promote continence. Hartmann's procedure is a reconstructive strategy rather than a method designed specifically to facilitate better bowel cleansing or irrigation access. Its focus is acute surgical stabilization. B. provide two stomas for fecal elimination.: A double-barrel colostomy involves two distinct stomas, whereas a Hartmann's procedure results in only a single stoma. The distal segment is oversewn and left internally as a rectal pouch or Hartmann's pouch. It does not communicate with the abdominal wall for elimination. C. prevent chronic constipation.: Surgical diversion is not a treatment for functional constipation and can occasionally complicate bowel motility post-reversal. The procedure is an emergency intervention for life-threatening perforation or obstruction rather than a prophylactic measure for stool consistency. Constipation management remains a medical or dietary concern. D. allow healing of the bowel.: Diverting the fecal stream away from the site of inflammation or perforation prevents further contamination of the peritoneal cavity. This creates a quiescent environment for the distal rectal stump and pelvic tissues to recover before a second-stage reanastomosis. It ensures the safety of future surgical reconstruction.
