Nursing Elites

1. 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.

2. Dark, tarry stools indicate bleeding in which location of the GI tract?

• A. Upper colon.
• B. Lower colon.
• C. Upper GI tract.
• D. Small intestine.

Correct answer: C

Rationale: Dark, tarry stools indicate bleeding in the upper GI tract.

3. Lactulose (Chronulac) is prescribed for a client with a diagnosis of hepatic encephalopathy. The nurse would determine that this medication has had a therapeutic effect if which of the following is noted?

• A. Increased red blood cell count
• B. Decreased serum ammonia level
• C. Increased protein level
• D. Decreased white blood cell level

Correct answer: B

Rationale: Lactulose is prescribed for the client with hepatic encephalopathy to reduce bacterial breakdown of protein in the bowel. The medication creates an acidic environment in the bowel and causes the ammonia to leave the bloodstream and enter the colon. Ammonia then becomes trapped in the bowel. Lactulose also has a laxative effect that allows for the elimination of the ammonia.

4. The nurse is caring for a client with a diagnosis of cirrhosis and is monitoring the client for signs of portal hypertension. Which initial sign, if noted in the client, indicates the presence of portal hypertension?

• A. Flat neck veins
• B. Hypotension
• C. Weak pulse
• D. Crackles on auscultation of the lungs

Correct answer: D

Rationale: Clinical signs and symptoms or portal hypertension are identical to those of heart failure and include jugular vein distention, lung crackles, and decreased perfusion to all organs. Initially, the client may have hypertension, flushed skin, and a bounding pulse.

5. The nurse assesses the client's understanding of the relationship between body position and gastroesophageal reflux. Which response would indicate that the client understands measures to avoid problems with reflux while sleeping?

• A. I can elevate the foot of the bed 4 to 6 inches.
• B. I can sleep on my stomach with my head turned to the left.
• C. I can sleep on my back without a pillow under my head.
• D. I can elevate the head of the bed 4 to 6 inches.

Correct answer: D

Rationale: Sleeping with the head of the bed elevated encourages movement of food through the esophagus by gravity. By fostering esophageal acid clearance, gravity helps keep the acidic pepsin and alkaline biliary secretions from contacting the esophagus. Elevating the foot of the bed does not affect clearance of esophageal acid. Sleeping on the stomach with the head turned to the left will not decrease reflux incidence. Sleeping flat without a pillow under the head does not enhance clearance.
