Gastrointestinal System Nursing Exam Questions

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: Cigarette smoking should be avoided because of its stimulatory effect on gastric secretions. Nicotine also increases the release of epinephrine, which leads to vasoconstriction. The client may chew gum if desired. The client may eat chocolate if desired. A client with a peptic ulcer should check with the physician before taking any over-the-counter drug, but acetaminophen does not typically cause gastric irritation.

Correct Answer: D

Rationale: Evaluating the absorption of the last feeding is important because administration of a tube feeding to a full stomach could result in overdistention, thus predisposing the client to regurgitation and possible aspiration.

Correct Answer: C

Rationale: Although no special diet is required to treat viral hepatitis, it is generally recommended that clients consume a diet with low-fat content because fat may be tolerated poorly due to decreased bile production. Small, frequent meals are preferable and may prevent nausea. Appetite is often better in the morning, so it is easier to eat a good breakfast. An adequate fluid intake of 2500 to 3000 mL per day that includes nutritional juices is also important.

Correct Answer: A

Rationale: Pain, fever, and abdominal rigidity are signs and symptoms of inflammation or peritonitis caused by the leaking anastomosis. Diarrhea with fat in the stool is steatorrhea and is not present in peritonitis. Palpitations, pallor, and diaphoresis after eating are vasomotor symptoms of gastric retention. Feelings of fullness and nausea after eating are not present in peritonitis.
