2. A nurse has been caring for a client with a Sengstaken-Blakemore tube. The physician arrives on the nursing unit and deflates the esophageal balloon. The nurse should monitor the client most closely for which of the following?
- A. Swelling of the abdomen
- B. Bloody diarrhea
- C. Vomiting blood
- D. An elevated temperature and arise in blood pressure
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: C
Rationale: Mucosal barrier fortifiers stimulate mucus production, which helps protect the lining of the stomach and manage peptic ulcer disease.

- D. Blood urea nitrogen
Correct answer: C

Elevated blood urea nitrogen may indicate renal dysfunction. A hemoglobin level is unrelated to this diagnosis.
