Nursing Elites

1. The patient described in the preceding questions has a positive H. pylori antibody blood test. She is compliant with the medical regimen you prescribe. Although her symptoms initially respond, she returns to see you six months later with the same symptoms. Which of the following statements is correct?

• A. She is at high risk for reinfection with H. pylori.
• B. A positive serum IgG indicates that eradication of H. pylori was unsuccessful.
• C. The urease breath test is an ideal test to document failure of eradication.
• D. Dyspepsia usually improves with H. pylori eradication.

Correct answer: C

Rationale: Reinfection with H. pylori is rare, and the persistence of infection usually indicates poor compliance with the medical regimen or antibiotic resistance. A positive serum IgG may persist indefinitely and cannot alone determine the failure of eradication. However, a decrease in quantitative IgG levels has been used to confirm treatment success. The urease breath test is recommended to assess the failure of eradication as it can detect the presence of H. pylori in the stomach, indicating treatment failure if positive.

2. 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.

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. A healthcare professional is interested in studying the incidence of infant death in a particular city and wants to compare that city's rate to the state's rate. What state resource is most likely to provide this information?

• A. Disease registry.
• B. Department of Health.
• C. Bureau of Vital Statistics.
• D. Census data.

Correct answer: C

Rationale: The Bureau of Vital Statistics collects data on births and deaths, including infant mortality rates. This data is crucial for healthcare professionals to analyze and compare rates between different regions.

5. A patient with chronic heart failure is prescribed furosemide. What is the primary action of this medication?

• A. Increase cardiac output
• B. Reduce fluid retention
• C. Decrease heart rate
• D. Lower blood pressure

Correct answer: B

Rationale: Furosemide is a loop diuretic that acts by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased diuresis. By reducing fluid retention, furosemide helps decrease the workload on the heart in patients with chronic heart failure. This medication does not directly increase cardiac output, decrease heart rate, or lower blood pressure as its primary action.
