Nursing Elites

1. A client with heart failure is receiving digoxin (Lanoxin). Which finding indicates that the medication is effective?

• A. Increased heart rate.
• B. Decreased pedal edema.
• C. Elevated blood pressure.
• D. Improved urine output.

Correct answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.

2. 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.

3. A patient with Parkinson's disease is prescribed levodopa. What dietary modification should the nurse suggest to the patient?

• A. Increase intake of vitamin C.
• B. Limit foods high in protein.
• C. Avoid foods rich in fiber.
• D. Increase sodium intake.

Correct answer: B

Rationale: The correct answer is to limit foods high in protein. Patients taking levodopa should restrict their intake of protein-rich foods because protein can interfere with the absorption of the medication. Levodopa competes with dietary proteins for absorption in the small intestine, potentially reducing the effectiveness of the medication. Therefore, by reducing protein intake, the patient can enhance the absorption and therapeutic effects of levodopa. Increasing vitamin C intake is not necessary for patients prescribed with levodopa. Avoiding foods rich in fiber or increasing sodium intake are not directly related to optimizing levodopa therapy and might not benefit the patient's condition.

4. A healthcare professional is preparing to administer digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablets. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Rationale: To achieve the prescribed dose of 0.25 mg, the healthcare professional should administer 2 tablets of 0.125 mg each, totaling 0.25 mg.

5. The healthcare provider is caring for a client with Guillain-Barré syndrome. Which assessment finding requires the healthcare provider's immediate action?

• A. Loss of deep tendon reflexes.
• B. Ascending weakness.
• C. New onset of confusion.
• D. Decreased vital capacity.

Correct answer: D

Rationale: Decreased vital capacity is the most critical assessment finding in a client with Guillain-Barré syndrome as it indicates respiratory compromise. This requires immediate intervention to ensure adequate ventilation and prevent respiratory failure, a common complication of this syndrome. Monitoring and maintaining respiratory function are vital in these clients to prevent complications such as respiratory distress, hypoxia, and respiratory failure. Loss of deep tendon reflexes and ascending weakness are typical manifestations of Guillain-Barré syndrome but do not require immediate action compared to compromised respiratory function. New onset of confusion may be a concern but is not as immediately life-threatening as decreased vital capacity.
