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: To assist the client in adapting to changes in appearance, the nurse must encourage participation in self-care to foster independence and self-esteem. The nurse should encourage the client to ask questions to clarify misconceptions, learn ways to prevent the spread of hepatitis to reduce fear, and make appropriate decisions. Restricting visitors will reinforce the client's negative self-esteem.

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: Intrinsic factor is produced in the stomach but is used to aid in the absorption of vitamin B12 in the small intestine. Vitamin B12 is not absorbed in the large intestine (options 3 and 4).

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.
