Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: Laboratory findings do not establish the diagnosis of appendicitis, but often moderate elevation of the white blood cell count (leukocytosis) to 10,000 to 18,000 cells/mm3 occurs with a "shift to the left" (an increased number of immature white blood cells.).

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: Antibiotics are administered preoperatively to reduce the bacterial count in the colon. The client will be placed on a low residue diet to help cleanse the bowel before surgery but typically is not placed on NPO status until 8 to 12 hours before surgery. Laxatives and enemas may also be administered. Chest tubes would not be expected postoperatively. There is no need to limit the client's activity before surgery.

Correct Answer: B

Rationale: It is important for the client to have frequent rest periods. Repeated episodes of diarrhea interrupt sleep patterns, and poor nutrition may also cause the client to feel weak. If the client is experiencing a severe exacerbation of ulcerative colitis, bed rest may be ordered. Antidiarrheal medications can be used selectively in ulcerative colitis but are not recommended for regular use as they can lead to colonic dilation. The client should maintain a low-residue, high-calorie, caffeine-free diet.

Correct Answer: B

Rationale: A hallmark sign of acute pancreatitis is severe abdominal pain that is not relieved by vomiting. Nausea and vomiting are common presenting symptoms, with vomitus typically consisting of gastric and duodenal contents. Hypothermia is not a hallmark sign of acute pancreatitis. Fever, typically less than 38 degrees centigrade, is more common. Epigastric pain radiating to the neck area is not a characteristic sign of acute pancreatitis. Therefore, choice B is the correct answer.
