A 46-year-old man with a history of cirrhosis is brought in by his wife because he has been acting strangely. On examination, he is disoriented, ataxic, and has slurred speech. He is also hyperreflexic. His white blood cell count is normal. His hematocrit is 34%. Coagulation times are elevated. His ammonia level is normal. Which of the following statements regarding his management is correct?

  • A. He should be treated with a low-protein diet and lactulose
  • B. Lorazepam is not the drug of choice to control his behavior
  • C. He should not be placed on gentamicin prophylactically to prevent the development of peritonitis
  • D. If the patient complains of pain, acetaminophen should be avoided and nonsteroidal anti-inflammatory agents should be used
Correct Answer: A

Rationale: The correct answer is A: He should be treated with a low-protein diet and lactulose. This patient is presenting with hepatic encephalopathy, as evidenced by his altered mental status, ataxia, slurred speech, hyperreflexia, and normal ammonia level. The management of hepatic encephalopathy involves reducing the production of ammonia in the gut. Lactulose is a non-absorbable disaccharide that helps trap ammonia in the gut and promote its excretion in the feces. A low-protein diet is also recommended to decrease ammonia production.

Option B is incorrect because lorazepam is not the drug of choice for managing hepatic encephalopathy; it can worsen the condition. Option C is incorrect because gentamicin is not indicated in this scenario. Option D is incorrect because acetaminophen should be avoided in patients with liver disease due to the risk of hepatotoxicity; nonsteroidal anti-inflammatory drugs

A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?

  • A. Peptic stricture
  • B. Esophageal cancer
  • C. Achalasia
  • D. Esophageal spasm
Correct Answer: B

Rationale: The correct answer is B: Esophageal cancer. Given the patient's age, symptoms of difficulty swallowing and weight loss, along with a history of chronic heartburn not responding to proton-pump inhibitors, esophageal cancer is the most likely diagnosis. Esophageal cancer commonly presents with dysphagia, weight loss, and a history of chronic reflux. Peptic stricture (A) typically presents with dysphagia but is less likely given the worsening symptoms despite treatment. Achalasia (C) presents with dysphagia and regurgitation, but not typically with weight loss. Esophageal spasm (D) presents with chest pain and dysphagia, but not typically with weight loss or chronic heartburn.

A 35-year-old man presents with difficulty swallowing, weight loss, and regurgitation of undigested food. A barium swallow shows a 'bird beak' appearance of the lower esophagus. What is the most likely diagnosis?

  • A. Esophageal cancer
  • B. Achalasia
  • C. Peptic stricture
  • D. Gastroesophageal reflux disease
Correct Answer: B

Rationale: The correct answer is B: Achalasia. The presentation of difficulty swallowing, weight loss, regurgitation of undigested food, and 'bird beak' appearance on barium swallow are classic for achalasia. In achalasia, there is impaired relaxation of the lower esophageal sphincter and absent peristalsis in the esophagus. This leads to functional obstruction and dilation of the esophagus, causing the characteristic 'bird beak' appearance.

Incorrect Choices:
A: Esophageal cancer typically presents with progressive dysphagia, weight loss, and may show a mass or stricture on imaging.
C: Peptic stricture is usually seen in patients with long-standing gastroesophageal reflux disease or esophagitis. Symptoms are often related to acid reflux.
D: Gastroesophageal reflux disease commonly presents with heartburn, regurgitation, and chest pain. It does not typically cause weight loss or the 'bird

The healthcare provider is preparing to administer a blood transfusion. Which action is most important to ensure client safety?

  • A. Check the client's vital signs before starting the transfusion.
  • B. Verify the client's identity and blood compatibility.
  • C. Administer the blood with normal saline.
  • D. Monitor the client for the first 15 minutes of the transfusion.
Correct Answer: B

Rationale: The correct answer is B: Verify the client's identity and blood compatibility. This step is crucial to prevent transfusion reactions due to compatibility issues. By confirming the client's identity and ensuring that the blood type matches, the healthcare provider minimizes the risk of adverse reactions such as hemolytic transfusion reactions. Checking vital signs (A) is important but ensuring blood compatibility takes precedence. Administering blood with normal saline (C) is incorrect as blood should be infused with the appropriate blood administration set. Monitoring the client for the first 15 minutes (D) is essential but verification of identity and blood compatibility is the primary step to prioritize safety.

A 55-year-old man presents with jaundice, pruritus, and dark urine. Laboratory tests reveal elevated bilirubin and alkaline phosphatase. Imaging shows dilated intrahepatic bile ducts and a normal common bile duct. What is the most likely diagnosis?

  • A. Primary biliary cirrhosis
  • B. Primary sclerosing cholangitis
  • C. Gallstones
  • D. Pancreatic cancer
Correct Answer: A

Rationale: The most likely diagnosis is Primary biliary cirrhosis (PBC). PBC typically presents with jaundice, pruritus, and dark urine due to impaired bile flow. Elevated bilirubin and alkaline phosphatase levels are common in PBC. Imaging findings of dilated intrahepatic bile ducts and a normal common bile duct support the diagnosis of PBC. Primary sclerosing cholangitis (Choice B) would show strictures and beading of bile ducts on imaging. Gallstones (Choice C) would typically present with a common bile duct obstruction. Pancreatic cancer (Choice D) may present with similar symptoms but is less likely given the specific imaging findings in this case.

In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?

  • A. A dedicated small bowel series has a high likelihood of being positive
  • B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor
  • C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss
  • D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations
Correct Answer: B

Rationale: The correct answer is B: 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor. Aspirin, a non-selective COX inhibitor, can interfere with the action of selective COX II inhibitors by competing for the same binding site on the COX enzyme. This competition can limit the effectiveness of the COX II inhibitor in reducing inflammation and pain. This is particularly important in patients with a history of chronic iron deficiency anemia who may require NSAIDs for pain management.

Option A is incorrect because a dedicated small bowel series may not necessarily be positive for identifying the source of blood loss in this patient. Option C is incorrect as a provocative arteriogram with heparin infusion is an invasive procedure and not typically indicated as a first-line investigation for blood loss in patients with iron deficiency anemia. Option D is incorrect as hormonal therapy is not typically used to decrease blood loss from arteriovenous malformations.
