1. Which of the following statements about Helicobacter pylori (H. pylori) is false?

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

2. A 50-year-old man presents with progressive jaundice, dark urine, and pruritus. Imaging reveals a mass in the head of the pancreas. What is the most likely diagnosis?

Correct answer: A

Rationale: The presentation of progressive jaundice, dark urine, and pruritus along with a pancreatic mass, particularly in the head of the pancreas, strongly suggests pancreatic cancer as the most likely diagnosis. These symptoms are classic for obstructive jaundice caused by a mass in the head of the pancreas, making pancreatic cancer the most fitting choice.

3. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?

Correct answer: A

Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.

4. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

5. The healthcare provider is providing care to a client with a tracheostomy. Which action should the healthcare provider take to prevent tracheostomy complications?

Correct answer: A

Rationale: Using sterile technique when performing tracheostomy care is essential to prevent infections and other complications. Proper sterile technique helps reduce the risk of introducing harmful bacteria into the tracheostomy site, which can lead to infections and other serious issues. By maintaining a sterile environment during tracheostomy care, the healthcare provider can promote healing and prevent potential complications.
