1. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

2. A client with a history of chronic alcohol abuse is at risk for which of the following conditions?

• A. Liver cirrhosis
• B. Renal failure
• C. Chronic obstructive pulmonary disease (COPD)
• D. Peptic ulcer disease

Correct answer: A

Rationale: Chronic alcohol abuse can lead to liver cirrhosis due to long-term liver damage. Alcohol consumption over time can cause inflammation and scarring of the liver, eventually leading to cirrhosis. This condition can severely impact liver function and may progress to liver failure if not addressed.

3. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

4. What side effect should be monitored for in a patient with chronic heart failure taking spironolactone?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypernatremia

Correct answer: B

Rationale: The correct answer is B: Hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in patients with heart failure. One of the potential side effects of spironolactone therapy is hyperkalemia, which is an elevated level of potassium in the blood. Hyperkalemia can lead to serious cardiac arrhythmias, making it crucial for healthcare providers to monitor potassium levels closely. Choices A, C, and D are incorrect because hypokalemia (low potassium levels), hyponatremia (low sodium levels), and hypernatremia (high sodium levels) are not typically associated with spironolactone use in patients with chronic heart failure.

5. 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.
