Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: Foods that help to thicken the stool of the client with an ileostomy include pasta, boiled rice, and low-fat cheese. Bran is high in dietary fiber and thus will increase the output of watery stool by increasing propulsion through the bowel. Ileostomy output is liquid. Addition or elimination of various foods can help to thicken or loosen this liquid drainage.

Correct Answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

Correct Answer: C

Rationale: The lower esophageal sphincter is a functional sphincter that normally remains closed except when food or fluids are swallowed. If relaxation of this sphincter occurs, the client could experience symptoms of gastroesophageal reflux disease.

Correct Answer: C

Rationale: Peripheral tissue perfusion is a major concern in the postoperative period following an abdominal aneurysm repair. Peripheral pulses should be checked frequently during the first 24 hours. A weak or absent pulse may be a sign of embolization or graft closure, especially if accompanied by a pale, cold, mottled extremity; the nurse should immediately report this to the surgeon. Risk for infection, deficient knowledge, and activity intolerance are all important nursing diagnoses in the postoperative period, but peripheral tissue perfusion is the most immediate concern.

Correct Answer: B

Rationale: Small, frequent feedings are better tolerated by clients with ulcerative colitis as they lessen the amount of fecal material present in the gastrointestinal tract and decrease stimulation. The client does not need to maintain a daily record of intake and output unless an exacerbation of the disease occurs. A heating pad should not be applied to the intestine as it is inflamed. It is not inevitable that the client will require surgery to treat ulcerative colitis.
