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 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 prior to initiating the Coumadin
• B. Check the client’s INR prior to beginning Coumadin
• C. Clarify the order with the health care provider as soon as possible
• D. Administer the Coumadin along with the heparin drip as ordered

Correct answer: D

Rationale: The correct action for the nurse to take 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 prior to initiating Coumadin could leave the patient without anticoagulation coverage during the period when warfarin's effects are not yet established. Checking the client's INR prior to beginning Coumadin is important but not the immediate action to take when both medications are ordered together. Clarifying the order with the health care provider is unnecessary in this scenario as it is common practice to give heparin and warfarin concurrently in the transition period.

3. In patients receiving chemotherapy, which nutrient is often supplemented to manage mucositis?

• A. Vitamin E
• B. Vitamin B12
• C. Zinc
• D. Calcium

Correct answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

4. The nurse is teaching the client diagnosed with Type 2 diabetes mellitus about diet. Which diet selection indicates the client understands the teaching?

• A. A submarine sandwich, potato chips, and diet cola
• B. Four (4) slices of a supreme thin-crust pizza and milk
• C. Smoked turkey sandwich, celery sticks, and unsweetened tea
• D. A roast beef sandwich, fried onion rings, and a cola

Correct answer: C

Rationale: The correct answer is C because a smoked turkey sandwich with celery sticks and unsweetened tea is a healthier option for someone with Type 2 diabetes mellitus. Turkey is a lean protein source, celery sticks are low in calories and carbs, and unsweetened tea is a better choice than sugary beverages. Choices A, B, and D are incorrect. Choice A includes high-carb and high-sugar items like potato chips and diet cola, which are not ideal for diabetes management. Choice B contains a high-carb pizza and milk, which may not be suitable for controlling blood sugar levels. Choice D includes fried onion rings and cola, which are high in unhealthy fats and sugars, making it a poor choice for a diabetic diet.

5. People who use monoamine oxidase inhibitors for the treatment of depression need to avoid foods high in:

• A. Folate
• B. Tyramine
• C. Potassium
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B: Tyramine. When individuals taking monoamine oxidase inhibitors (MAOIs) consume foods high in tyramine, it can lead to a potentially dangerous increase in blood pressure known as a hypertensive crisis. Foods high in tyramine include aged cheeses, cured meats, and certain fermented foods. Choices A, C, and D are incorrect. Folate, potassium, and vitamin K are not typically contraindicated with the use of MAOIs.
