Nursing Elites

1. A 56-year-old white male complains of intermittent dysphagia for the past three months, particularly with the ingestion of meat. He has no difficulties swallowing liquids. He has no history of smoking, uses no medications, and has had no weight loss. What test would be best to evaluate him?

• A. Upper endoscopy
• B. Chest/abdominal CT scan
• C. Barium swallow
• D. Esophageal manometry

Correct answer: C

Rationale: For a patient presenting with intermittent dysphagia, especially with solids like meat, a barium swallow is the most appropriate initial test. In this case, the classic presentation suggests a Schatzki’s ring, which is best visualized through a barium study. Upper endoscopy may not always visualize Schatzki’s rings effectively. Chest/abdominal CT scan and esophageal manometry are not the preferred tests for diagnosing Schatzki’s rings. Treatment for Schatzki’s rings often involves bougie dilatation, and no further therapy may be necessary.

2. What is the primary action of digoxin when prescribed to a patient with heart failure?

• A. Increase heart rate
• B. Decrease cardiac output
• C. Strengthen cardiac contractions
• D. Lower blood pressure

Correct answer: C

Rationale: Digoxin, when prescribed to a patient with heart failure, primarily acts by strengthening cardiac contractions. This leads to an improvement in cardiac output, making it an essential medication in managing heart failure. By enhancing the force of contractions, digoxin helps the heart pump more effectively and efficiently, leading to better circulation and symptom control in patients with compromised cardiac function.

3. 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: This patient presents with symptoms consistent with hepatic encephalopathy. Despite having a normal ammonia level, he should be treated with lactulose and a low-protein diet as recommended for stage 2 hepatic encephalopathy. The normal ammonia level does not exclude the diagnosis, as it lacks sensitivity and specificity. Medications like lorazepam, gentamicin, and NSAIDs should be avoided due to their potential adverse effects in patients with liver disease. Acetaminophen should also be avoided in such patients.

4. The nurse is providing an educational workshop about coronary artery disease (CAD) and its risk factors. The nurse explains to participants that CAD has many risk factors, some that can be controlled and some that cannot. What risk factors should the nurse list that can be controlled or modified?

• A. Gender, obesity, family history, and smoking
• B. Inactivity, stress, gender, and smoking
• C. Cholesterol levels, hypertension, and smoking
• D. Stress, family history, and obesity

Correct answer: C

Rationale: Cholesterol levels, hypertension, and smoking are controllable risk factors for CAD. Managing these factors through lifestyle changes and medical interventions can help reduce the risk of developing coronary artery disease.

5. A 60-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Hepatitis C
• B. Primary biliary cirrhosis
• C. Hemochromatosis
• D. Wilson's disease

Correct answer: B

Rationale: The symptoms of fatigue, pruritus, jaundice, and elevated bilirubin and alkaline phosphatase levels are classic features of primary biliary cirrhosis, an autoimmune liver disease. Hepatitis C typically presents with different symptoms and findings, such as specific viral markers. Hemochromatosis and Wilson's disease involve iron overload and copper accumulation, respectively, leading to distinct clinical and laboratory findings, which do not match the presentation described in this case.
