Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: A Sengstaken-Blakemore tube is inserted into a client with a diagnosis of cirrhosis and ruptured esophageal varices. The tube has an esophageal and a gastric balloon. The esophageal balloon exerts pressure on the bleeding. The pressure of the esophageal balloon is released at intervals to decrease the risk of trauma to esophageal tissues, including esophageal rupture or necrosis. When the balloon is deflated the client may begin to bleed again from the esophageal varices, noted by vomiting of blood.

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: A

Rationale: A realistic goal for this client would be to gain relief from epigastric pain. There is no need for vitamin B12 injections because this client has not had any gastric surgery that would lead to vitamin B12 deficiency. Exercise should be modified, not increased, because it can stimulate further production of gastric acid. It is not possible to eliminate stress from a client's life. Instead, the client should be assisted to develop effective coping and problem-solving strategies as necessary.

Correct Answer: D

Rationale: The correct answer is D. This patient statement indicates a need for further teaching. The patient should be instructed that, in order to avoid complications, alcohol should be avoided for six months to one year. Illicit drugs and toxic chemicals should also be avoided. Acetaminophen may be taken only when necessary and not beyond the recommended dosage. Choices A, B, and C are correct statements regarding precautions to prevent the spread of hepatitis B and do not indicate a need for further instruction.

Correct Answer: B

Rationale: As peristalsis returns following creation of a colostomy, the client begins to pass malodorous flatus. This indicates returning bowel function and is an expected event. Within 72 hours of surgery, the client should begin passing stool via the colostomy.
