Gastrointestinal System Nursing Exam Questions

Correct Answer: C

Rationale: A sign indicating that a client's colostomy is open and ready to function is passage of feces and flatus. When this occurs, gastric suction is ordinarily discontinued, and the client is allowed to start taking fluids and food orally. Absence of bowel sounds would indicate that the tube should remain in place because peristalsis has not yet returned. Absence of nausea and vomiting is not a criterion for judging whether or not gastric suction should be continued. Passage of mucus from the rectum will not occur in this client because the rectum is removed in this surgery. Absence of stomach drainage is not a criterion for judging whether or not gastric suction should be continued.

Correct Answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

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.

Correct Answer: B

Rationale: When the nurse removes a nasogastric tube, the client is instructed to take and hold a deep breath. This will be obstructed temporarily during the tube removal. This allows for easy withdrawal through the esophagus into the nose. The nurse removes the tube with one smooth, continuous pull.

Correct Answer: A

Rationale: Following this procedure, the nurse monitors the client's vital signs closely for indications of hemorrhage and observes the needle insertion site for bleeding and bile leakage. A sandbag is placed over the insertion site to prevent bleeding. The client is maintained on bedrest, and oral intake is avoided in the immediate postprocedure period in case surgery is necessary to control hemorrhage of bile extravasation.
