1. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.

2. What is the primary goal of care for a client experiencing esophageal varices secondary to liver cirrhosis?

• A. Preventing infection
• B. Controlling bleeding
• C. Reducing portal hypertension
• D. Maintaining nutritional status

Correct answer: B

Rationale: The primary goal of care for a client with esophageal varices secondary to liver cirrhosis is to control bleeding. Esophageal varices are fragile, enlarged veins in the esophagus that can rupture and lead to life-threatening bleeding. Controlling bleeding is crucial to prevent severe complications and ensure the client's safety and well-being. Preventing infection (Choice A) is important but not the primary goal in this case. Reducing portal hypertension (Choice C) is a long-term goal that may help prevent variceal bleeding but is not the immediate priority. Maintaining nutritional status (Choice D) is essential for overall health but is secondary to controlling bleeding in this critical situation.

3. A 70-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Gallstones
• B. Hepatitis
• C. Pancreatic cancer
• D. Primary biliary cirrhosis

Correct answer: C

Rationale: The presentation of a 70-year-old man with weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels is highly suggestive of pancreatic cancer. This clinical scenario, known as Courvoisier's sign, points towards a pancreatic malignancy due to biliary obstruction. Gallstones could cause similar symptoms but would typically not present with a palpable mass. Hepatitis usually does not present with a palpable mass and would have different laboratory findings. Primary biliary cirrhosis typically presents differently with chronic cholestasis without the presence of a palpable mass or a pancreatic lesion.

4. What is the best therapy for a 65-year-old man with symptoms of regurgitation, chest pain, dysphagia, weight loss, dilated esophagus, and an absent gastric air bubble on CXR?

• A. Proton-pump inhibitor
• B. Endoscopic balloon dilatation
• C. Sucralfate
• D. Esophageal resection

Correct answer: B

Rationale: The patient's presentation and radiologic findings are consistent with achalasia. The absence of a mass on upper endoscopy and CT scan helps rule out secondary causes. Achalasia is best managed with endoscopic balloon dilatation or myotomy. Proton-pump inhibitors are not effective for achalasia. Sucralfate is not a primary treatment for achalasia. Esophageal resection is only considered if malignancy develops. Patients with achalasia may experience chest pain and weight loss due to food accumulation in the dilated esophagus. Endoscopic balloon dilatation is a safe and effective treatment option for improving symptoms in achalasia patients.

5. An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?

• A. Corticosteroids
• B. Gamma globulin
• C. Hepatitis B vaccine
• D. Fresh frozen plasma

Correct answer: B

Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection. Therefore, the correct choice is Gamma globulin as it can provide immediate passive immunity against hepatitis B.
