The nurse is preparing a client for surgery and observes on the operative permit that the client will be having a double-barrel colostomy. What portion of the large intestine is the nurse aware that this is performed?
Ascending.
Descending.
Transverse.
Sigmoid.
The Correct Answer is D
sigmoid. A double-barrel colostomy involves surgically creating two separate stomas from the colon, with the proximal stoma discharging stool and the distal stoma discharging mucus. This type of colostomy is typically performed in the sigmoid colon, which is the S-shaped segment of the large intestine located just before the rectum.
Choice A, ascending, is not the correct answer because an ascending colostomy is created in the ascending colon, which is located on the right side of the abdomen.
Choice B, descending, is not the correct answer because a descending colostomy is created in the descending colon, which is located on the left side of the abdomen.
Choice C, transverse, is not the correct answer because a transverse colostomy is created in the transverse colon, which is located across the upper abdomen.
