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. The nurse is caring for a client in a sickle cell crisis. Which is the pain regimen of choice to relieve the pain?

• A. Frequent aspirin (acetylsalicylic acid) and a non-narcotic analgesic
• B. Motrin (ibuprofen), an NSAID, PRN
• C. Demerol (meperidine), a narcotic analgesic, every four (4) hours
• D. Morphine, a narcotic analgesic, every two (2) to three (3) hours PRN

Correct answer: D

Rationale: In a sickle cell crisis, morphine is the preferred analgesic due to its potency and effectiveness in managing severe pain. Choice A is incorrect because aspirin is contraindicated in sickle cell disease due to its potential to cause a further decrease in blood flow. Choice B, Motrin (ibuprofen), is also not the ideal choice as NSAIDs can exacerbate renal complications in sickle cell patients. Choice C, Demerol (meperidine), is not recommended for sickle cell pain management due to its toxic metabolite accumulation which can cause seizures and other complications.

3. Listed below are five categories that identify the responsibilities of the practical nurse manager in personnel management. Which of these categories is most appropriate for the task 'Know what your soldiers are doing during duty hours'?

• A. Accountability
• B. Personal/professional development
• C. Individual training
• D. Military appearance/physical condition

Correct answer: A

Rationale: The correct answer is 'Accountability.' This choice is the most appropriate for the task 'Know what your soldiers are doing during duty hours' as it directly relates to being responsible for and knowing the actions and whereabouts of individuals under supervision. 'Personal/professional development' (choice B) focuses on growth and advancement, 'Individual training' (choice C) pertains to specific skill development, and 'Military appearance/physical condition' (choice D) deals with the physical presentation and health of soldiers, none of which directly address the task of knowing soldiers' activities during duty hours.

4. Which nutrient deficiency is most likely to be seen in patients with chronic alcoholism?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin B12
• D. Vitamin B1

Correct answer: D

Rationale: In patients with chronic alcoholism, the most likely nutrient deficiency is Vitamin B1 (thiamine), not Vitamin B12. Chronic alcoholism often leads to Vitamin B1 deficiency, causing conditions like Wernicke's encephalopathy. While other vitamin deficiencies can also occur in chronic alcoholism, such as Vitamin C and Vitamin D, Vitamin B1 deficiency is more commonly associated with alcoholism.

5. Which of the following is a primary intervention for managing hyperphosphatemia?

• A. Increasing calcium intake
• B. Increasing phosphorus intake
• C. Decreasing calcium intake
• D. Administering phosphate binders

Correct answer: D

Rationale: The correct answer is D, administering phosphate binders. Phosphate binders are a primary intervention for managing hyperphosphatemia as they help by binding phosphorus in the gut, preventing its absorption. Increasing calcium intake (choice A) or phosphorus intake (choice B) would exacerbate hyperphosphatemia. Decreasing calcium intake (choice C) is not a primary intervention for managing high phosphorus levels.
