Ostomy Care ATI Exam With Questions And100% Accurate Answers
An ostomy is an opening - Answer surgically created in the abdominal wall to allow for
the elimination of urine or feces.
Ostomy surgery is performed - Answer when a disorder or an injury keeps the urinary or
gastrointestinal system from functioning properly.
Indications for ostomy surgery include: - Answer congenital anomalies
bladder, colon, and rectal cancer
inflammatory bowel diseases (Crohn's disease, ulcerative colitis)
inherited disorders such as familial adenomatous polyposis
obstruction of the ureter
stab or gunshot wounds to the abdomen
Depending on the disorder or injury, the ostomy may be temporary, to allow for healing
and a return to normal elimination, or permanent. The three main types of ostomy
surgery are: - Answer colostomy
ileostomy
urostomy
The surgically-created opening in the skin of the abdomen is called a - Answer stoma. A
stoma is the communicating end of the bladder or bowel that is brought to the surface of
the abdomen. The location of the stoma is based upon the location of the patient's
beltline, location of scars and skin folds, where the damage is located, and the type of
ostomy surgery performed. The stoma should appear shiny, wet, and red, like the
mucous membranes of the mouth. A stoma may be circular, oval, or irregular in shape
and may protrude, be at skin level, or be retracted.
,A colostomy is made from the end of the large intestine to reroute waste away from the
digestive system. Three types of colostomies can be made from the GI tract: - Answer 1.
End ( Hartmans pouch)
2. Loop
3. Double barrel
With an end colostomy, t - Answer 1. the diseased portion of the bowel is taken out and
the functioning end is brought through the abdomen to the skin surface.
2. When the colostomy is to be permanent, an end stoma is usually constructed.
3. A temporary colostomy may be carried out to allow bowel rest or healing, such as
after tumor resection.
A very common type of temporary colostomy involves leaving the distal portion of the
colon intact, oversewing for closure to create what is called a Hartmann's pouch. The
anastomosis of amputated parts of the colon may be postponed because of a number of
reasons such as bowels inflammation or tumors' location.
A loop colostomy With a loop colostomy, a loop of the bowel is brought through the
abdomen to the skin surface and temporarily supported by a plastic bridge or rod.
Usually, a transverse loop colostomy is performed as an emergency to divert the fecal
stream when there is an obstruction or perforation of the intestine. There is a
communicating wall that remains between the proximal and the distal bowel. It has two
openings through the one stoma - the proximal end drains stool while the distal portion
drains mucus. The bridge can be removed in 7 to 10 days. Transverse loop colostomies
are usually temporary.
Loop colostomy - Answer
With a double-barrel colostomy, Two separate stomas are created. Both ends of the
bowel are brought through the abdomen to the skin surface as two separate sections.
Typically the distal colon is not removed but bypassed. The proximal stoma, which is
functional, diverts feces to the abdominal wall. The distal stoma, or mucous fistula,
expels mucus from the distal colon.
, Depending on the site of disease or injury, as well as other abdominal physical
characteristics of the patient, a colostomy is placed in one of the following four sites: -
Answer 1. Ascending colon
2. Transvers colon
3. Descending Colon
4. Sigmoid Colon.
Ascending colon (right abdomen). - Answer The output is usually liquid to semi-liquid
and is highly irritating to the skin surrounding it.
Transverse colon (mid-abdomen). This site is utilized for a temporary ostomy, with the
stoma created as a loop. Output is liquid to semi-formed. - Answer output- liquid to
semiformed
Descending colon (left upper abdomen). - Answer The output is semi-formed because
more water is absorbed while fecal material is in the ascending and transverse colon.
Sigmoid colon (left lower abdomen). T - Answer his is the location for a permanent
colostomy, particularly for cancer of the rectum. The stoma is usually placed on the
lower left quadrant of the abdomen and the output is formed.
Ileostomy is an opening surgically created in the ileum to divert the flow of faeces out of
the body, bypassing the entire large intestine. Total proctocolectomy entails the
surgical removal of the entire colon, rectum, and anus with closure of the anus, thus
necessitating diversion of faeces. - Answer
Also part of total proctocolectomy surgery: -Answer 1. The terminal ileum end is routed
out through the abdominal wall, where it creates a permanent ileostomy.
2. After this type of ileostomy surgery the patient will have no voluntary bowel control.
3. The stoma of an ileostomy is typically placed in the right lower quadrant.
