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. The medical C4I headquarters has automated data processing systems that aid in which of the following?

• A. Patient accountability
• B. Tracking the movement of patients
• C. Management of health service logistics systems
• D. Patient accountability, tracking the movement of patients, and management of health service logistics systems

Correct answer: D

Rationale: The correct answer is D because the automated data processing systems in the medical C4I headquarters play a role in patient accountability, tracking the movement of patients, and managing health service logistics systems. These systems help in efficiently managing patient information, monitoring and coordinating patient movements, and optimizing the logistics involved in health services. Choices A, B, and C are incorrect because they represent individual aspects that are all encompassed by the functions of the automated data processing systems in the C4I headquarters.

3. Which of the following is a common side effect of the drug metformin?

• A. Weight loss
• B. Weight gain
• C. Drowsiness
• D. Hypertension

Correct answer: A

Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss in some individuals. Choices B, C, and D are incorrect. Weight gain is not a typical side effect of metformin. Drowsiness and hypertension are also not commonly associated with metformin use.

4. The nurse on the medical/surgical unit cares for a client with a diagnosis of cerebrovascular accident (CVA). The nursing assessment of the client’s neurological status should include which of the following? (Select all that apply)

• A. Obtain the pulses in all four extremities
• B. Ask the client to grasp and squeeze two fingers on each of the nurse’s hands
• C. Determine the client’s orientation to person, place, and time
• D. B, C

Correct answer: D

Rationale: The correct answer is 'D' because assessing grasp strength (choice B) and orientation to person, place, and time (choice C) are crucial components of a neurological assessment following a cerebrovascular accident (CVA). Pulse assessment in all four extremities (choice A) is not directly related to a neurological assessment and is more pertinent to vascular status. Therefore, choices A and D are incorrect in this context.

5. The client diagnosed with acute vein thrombosis is receiving a continuous heparin drip, an intravenous anticoagulant. The health care provider orders warfarin (Coumadin), an oral anticoagulant. Which action should the nurse take?

• A. Discontinue the heparin drip before initiating the Coumadin
• B. Check the client’s INR before beginning Coumadin
• C. Clarify the order with the healthcare provider as soon as possible
• D. Administer the Coumadin along with the heparin drip as ordered

Correct answer: D

Rationale: The correct answer is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip before initiating Coumadin can increase the risk of clot formation. Checking the client's INR before starting Coumadin is important but not the immediate action required. Clarifying the order with the healthcare provider is not necessary as both medications are commonly used together.
