Nursing Elites

1. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

2. For a patient on lithium therapy, which dietary recommendation is essential?

• A. Increase caffeine intake
• B. Increase sodium intake
• C. Increase protein intake
• D. Increase fiber intake

Correct answer: B

Rationale: The correct answer is to increase sodium intake. Maintaining consistent sodium levels is crucial for patients on lithium therapy to prevent fluctuations in drug levels. Increasing caffeine intake (Choice A) is not recommended as it can interfere with lithium levels. While protein intake (Choice C) is important, it is not the essential dietary recommendation for patients on lithium therapy. Similarly, increasing fiber intake (Choice D) is not a key recommendation for these patients.

3. A family came to the emergency department with complaints of food poisoning. Which client should the nurse see first?

• A. 32-year-old with diarrhea for 6 hours
• B. 2-year-old with 1 wet diaper in 24 hours
• C. 40-year-old with abdominal cramping
• D. 10-year-old who is nauseated

Correct answer: B

Rationale: In cases of food poisoning, a 2-year-old with reduced urine output is a critical finding indicating dehydration, requiring immediate attention to prevent complications. The reduced urine output is a sign of decreased fluid intake or increased fluid loss, putting the child at high risk for dehydration. This client should be seen first to assess hydration status, initiate necessary interventions, and prevent further complications. While the other symptoms presented by the other clients are concerning, the 2-year-old's decreased urine output poses the most immediate threat to their well-being.

4. What is the mission of the Army Medical Department?

• A. Ensure that each soldier receives a physical examination each year
• B. Provide health care to areas of the U.S. declared disaster zones by the President
• C. Maintain the health of the Army and conserve its fighting strength
• D. Offer medical, dental, and veterinary education and training

Correct answer: C

Rationale: The correct answer is C: 'Maintain the health of the Army and conserve its fighting strength.' This mission statement reflects the primary goal of the Army Medical Department, which is to ensure the overall health and readiness of military personnel. Choices A, B, and D are incorrect because they do not fully capture the core purpose of the Army Medical Department. While providing physical examinations, healthcare in disaster areas, and education/training are important aspects, the central mission is to uphold the health and combat readiness of the Army.

5. A patient with chronic renal failure should avoid which of the following?

• A. Potassium
• B. Calcium
• C. Iron
• D. Zinc

Correct answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.
