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 nurse is teaching a community class to people with Type 2 diabetes mellitus. Which explanation would explain the development of Type 2 diabetes?

• A. The islet cells in the pancreas stop producing insulin
• B. The client eats too many foods that are high in sugar
• C. The pituitary gland does not produce vasopressin
• D. The cells become resistant to the circulating insulin

Correct answer: D

Rationale: In Type 2 diabetes, the primary issue is insulin resistance, where cells do not respond effectively to insulin. Choice A is incorrect as in Type 1 diabetes the islet cells in the pancreas stop producing insulin. Choice B is incorrect as while excessive sugar intake can contribute to the development of Type 2 diabetes, it is not the primary cause. Choice C is incorrect as the pituitary gland's function is unrelated to the development of Type 2 diabetes.

3. Performing and supervising therapeutic and preventive procedures that have been planned for a patient is part of which of the following steps for determining and fulfilling the nursing care needs of the patient?

• A. Evaluation
• B. Planning
• C. Implementation
• D. Assessment

Correct answer: C

Rationale: The correct answer is C: Implementation. Implementation in nursing care involves the actual performance and supervision of the planned therapeutic and preventive procedures for a patient. Evaluation (choice A) is the step where the effectiveness of the interventions is assessed. Planning (choice B) is the phase where the nursing care plan is developed based on the assessment. Assessment (choice D) is the initial step in the nursing process, involving data collection and analysis to determine the patient's needs.

4. 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.

5. A patient taking anticoagulants should be cautious about consuming which type of food?

• A. High-protein foods
• B. High-fiber foods
• C. High-vitamin K foods
• D. High-calcium foods

Correct answer: C

Rationale: The correct answer is C: High-vitamin K foods. Foods high in vitamin K can interfere with the effectiveness of anticoagulants. Vitamin K plays a crucial role in blood clotting, so consuming high amounts of it can counteract the anticoagulant effects. Choices A, B, and D are incorrect as they do not directly interfere with the action of anticoagulants.
