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 works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

2. After undergoing a pericardiocentesis, which interventions should the nurse implement?

• A. Monitor vital signs every 15 minutes for the first hour
• B. Evaluate the client’s cardiac rhythm
• C. Record the amount of fluid removed as output
• D. All of the above

Correct answer: D

Rationale: Following a pericardiocentesis, it is crucial for the nurse to monitor vital signs regularly, evaluate cardiac rhythm, and record the amount of fluid removed as output to detect any complications promptly. These interventions help in ensuring the client's safety and detecting any potential issues early. Therefore, selecting 'All of the above' (Choice D) is the correct answer as it encompasses all the essential interventions required post-pericardiocentesis. Choices A, B, and C are necessary actions to provide comprehensive care and monitor the client effectively.

3. The nurse prepares to administer digoxin (Lanoxin) to a newborn with a diagnosis of heart failure and notes that the apical rate is 140 beats per minute. Which nursing action is appropriate?

• A. Hold the medication
• B. Administer the digoxin
• C. Notify the healthcare provider
• D. Recheck the apical rate in 1 hour

Correct answer: B

Rationale: The correct answer is to administer the digoxin. An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly prescribed for heart failure in newborns to help improve cardiac function. Holding the medication or notifying the healthcare provider is not necessary as the heart rate is normal for a newborn. Rechecking the apical rate in 1 hour is not needed since the heart rate is within the expected range.

4. The Army Medical Department has four major functions. Three are prevention, treatment, and evacuation. What is the fourth?

• A. Preparation
• B. Training
• C. Mobilization
• D. Selection

Correct answer: C

Rationale: The correct answer is C, 'Mobilization.' Mobilization is the fourth major function of the Army Medical Department. This involves preparing and organizing medical resources and personnel for deployment during military operations. Choices A, B, and D are incorrect because while they are important aspects in military healthcare, they do not represent the fourth major function of the Army Medical Department as specifically requested in the question.

5. A patient with Crohn’s disease is experiencing diarrhea. Which dietary recommendation is appropriate?

• A. High-fiber diet
• B. Low-residue diet
• C. High-fat diet
• D. High-protein diet

Correct answer: B

Rationale: A low-residue diet is the appropriate dietary recommendation for a patient with Crohn’s disease experiencing diarrhea. This diet helps reduce bowel movements and manage diarrhea by limiting the intake of foods that are harder to digest. High-fiber diets (Choice A) may worsen diarrhea due to increased bulk in the stool. High-fat diets (Choice C) can be harder to digest and may exacerbate symptoms. High-protein diets (Choice D) are not specifically recommended for managing diarrhea in Crohn’s disease.
