1. The most important pathophysiologic factor contributing to the formation of esophageal varices is:

• A. Decreased prothrombin formation
• B. Decreased albumin formation by the liver
• C. Portal hypertension
• D. Increased central venous pressure

Correct answer: C

Rationale: Portal hypertension is the most important pathophysiologic factor contributing to the formation of esophageal varices.

2. Kevin has a history of peptic ulcer disease and vomits coffee-ground emesis. What does this indicate?

• A. He has fresh, active upper GI bleeding.
• B. He needs immediate saline gastric lavage.
• C. His gastric bleeding occurred 2 hours earlier.
• D. He needs a transfusion of packed RBCs.

Correct answer: C

Rationale: Coffee-ground emesis is a sign of upper gastrointestinal bleeding that occurred approximately 2 hours earlier. It results from the breakdown of blood in the stomach due to digestive enzymes, giving it a coffee-ground appearance. Choice A is incorrect because coffee-ground emesis indicates older, partially digested blood, not fresh active bleeding. Choice B is incorrect as gastric lavage is not indicated for coffee-ground emesis. Choice D is incorrect because a transfusion of packed RBCs is not the immediate management for this presentation.

3. A nurse is assigned to a 40-year-old client who has a diagnosis of chronic pancreatitis. The nurse reviews the laboratory result, anticipating a laboratory report that indicates a serum amylase level of

• A. 45 units/L
• B. 100 units/L
• C. 300 units/L
• D. 500 units/L

Correct answer: C

Rationale: The normal serum amylase level is 25 to 151 IU/L. With chronic cases of pancreatitis, the rise in serum amylase levels usually does not exceed three times the normal value. In acute pancreatitis, the value may exceed five times the normal value. Options 1 and 2 are within normal limits. Option 3 is an extremely elevated level seen in acute pancreatitis.

Correct answer: A

Rationale: Asterixis, a flapping tremor of the hands, is a sign of hepatic encephalopathy.

5. A patient with chronic alcohol abuse is admitted with liver failure. You closely monitor the patient’s blood pressure because of which change that is associated with the liver failure?

• A. Hypoalbuminemia
• B. Increased capillary permeability
• C. Abnormal peripheral vasodilation
• D. Excess rennin release from the kidneys

Correct answer: C

Rationale: Abnormal peripheral vasodilation is a change associated with liver failure that requires close monitoring of the patient's blood pressure.
