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: A

Rationale: The client should be taught to include deodorizing foods in the diet, such as beet greens, parsley, buttermilk, and yogurt. Spinach also reduces odor but is a gas-forming food as well. Broccoli, cucumber, and eggs are gas-forming foods.

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.

Correct Answer: B

Rationale: Cholestyramine resin binds with bile salts in the intestines to form a compound that is excreted in the feces. The client should be instructed to mix the medication with 3 to 6 oz of water, milk, fruit juice, or soup. The medication should be administered before meals. The medication is not administered via rectal suppository.

Correct Answer: B

Rationale: Water-soluble lubricant is used to lubricate 3 to 4 inches of the tube at the insertion end. An oil lubricant is not used because if the tube accidentally goes into the bronchus, pneumonia can develop. Half-inch tape is used to secure the tube after the correct placement is verified. A 50-mL catheter tip syringe is used to aspirate gastric contents to confirm placement. The client will be asked to take a sip of water through a straw to help with the passage of the tube.
