Nursing Elites

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

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

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 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 'bird beak' appearance on a barium swallow is characteristic of achalasia, a condition where the lower esophageal sphincter fails to relax properly. This leads to difficulty swallowing, weight loss, and regurgitation of undigested food, which are hallmark symptoms of achalasia.

3. A 60-year-old male client is admitted to the hospital with the complaint of right knee pain for the past week. His right knee and calf are warm and edematous. He has a history of diabetes and arthritis. Which neurological assessment action should the nurse perform for this client?

• A. Glasgow Coma Scale
• B. Assess pulses, paresthesia, and paralysis distal to the right knee
• C. Assess pulses, paresthesia, and paralysis proximal to the right knee
• D. Optic nerve using an ophthalmoscope

Correct answer: B

Rationale: In this scenario, the nurse should assess pulses, paresthesia, and paralysis distal to the right knee to evaluate for neurovascular compromise. This assessment helps determine the perfusion and sensation of the lower extremity, which is crucial in identifying potential vascular or nerve damage that may be causing the client's symptoms.

4. A 55-year-old man presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. 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 constellation of symptoms including fatigue, pruritus, and jaundice, along with elevated bilirubin and alkaline phosphatase levels, and imaging findings of dilated intrahepatic bile ducts and a normal common bile duct, are classical features of primary biliary cirrhosis.

5. A patient with systemic lupus erythematosus (SLE) is prescribed hydroxychloroquine. What is the most important instruction the nurse should give?

• A. Report any vision changes immediately.
• B. Take the medication with milk.
• C. Avoid high-fat foods.
• D. Increase intake of green leafy vegetables.

Correct answer: A

Rationale: The correct instruction for a patient prescribed hydroxychloroquine, especially in the context of systemic lupus erythematosus (SLE), is to report any vision changes immediately. Hydroxychloroquine can potentially cause retinal damage, so prompt reporting and ophthalmologic evaluation are essential in preventing irreversible eye complications. Choices B, C, and D are incorrect because they do not address the significant adverse effect of hydroxychloroquine on vision. Taking the medication with milk, avoiding high-fat foods, or increasing intake of green leafy vegetables are not relevant to the primary concern of monitoring for visual changes.
