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. A client who is postpartum and diagnosed with iron deficiency anemia is receiving education from a nurse. Which dietary recommendation should be included in the education plan?

• A. Yogurt and mozzarella
• B. Spinach and beef
• C. Fish and cottage cheese
• D. Turkey slices and milk

Correct answer: B

Rationale: The correct answer is B: Spinach and beef. Spinach is a good source of non-heme iron, while beef provides heme iron, both essential for treating iron deficiency anemia. Yogurt and mozzarella (choice A) are not significant sources of iron. Fish and cottage cheese (choice C) do not provide as much iron as spinach and beef. Turkey slices and milk (choice D) are also not as rich in iron compared to spinach and beef.

3. The client diagnosed with thalassemia, a hereditary anemia, is to receive a transfusion of packed RBCs. The cross-match reveals the presence of antibodies that cannot be cross-matched. Which precaution should the nurse implement when initiating the transfusion?

• A. Start the transfusion at 10-15 mL per hour for 15-30 minutes
• B. Re-crossmatch the blood until the antibodies are identified
• C. Have the client sign a permit to receive uncrossmatched blood
• D. Have the unlicensed nursing assistant stay with the client

Correct answer: A

Rationale: Starting the transfusion slowly at 10-15 mL per hour for 15-30 minutes is essential when the cross-match reveals the presence of antibodies that cannot be cross-matched. This precaution allows the nurse to monitor for any adverse reactions due to the antibodies. Re-crossmatching the blood until the antibodies are identified (choice B) may delay the transfusion process and put the client at risk. Having the client sign a permit to receive uncrossmatched blood (choice C) is not a standard practice and does not address the immediate need for precautions during transfusion. Having the unlicensed nursing assistant stay with the client (choice D) is unrelated to the safe initiation of the transfusion and is not a precaution specific to managing antibodies in blood products.

4. The nurse is caring for clients on a medical floor. Which client will the nurse assess first?

• A. The client with an abdominal aortic aneurysm who is constipated
• B. The client on bed rest who ambulated to the bathroom
• C. The client with essential hypertension who has epistaxis and a headache
• D. The client with arterial occlusive disease who has a decreased pedal pulse

Correct answer: C

Rationale: The correct answer is C because epistaxis and headache in a client with hypertension are signs of a hypertensive crisis, requiring immediate intervention. Option A is incorrect as constipation in a client with an abdominal aortic aneurysm, though important, does not indicate an immediate need for assessment. Option B, a client on bed rest who ambulated to the bathroom, does not present with urgent signs or symptoms requiring immediate assessment. Option D, a client with arterial occlusive disease and a decreased pedal pulse, needs attention but is not the priority compared to a hypertensive crisis with epistaxis and headache.

5. Which dietary change is most beneficial for a patient with hypertension?

• A. Increased sodium intake
• B. Decreased potassium intake
• C. Increased fiber intake
• D. Increased cholesterol intake

Correct answer: C

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increasing fiber intake can aid in managing hypertension by promoting heart health and overall well-being. Choices A, B, and D are incorrect. Increased sodium intake is not recommended for hypertension as it can elevate blood pressure. Decreasing potassium intake is also not advised as potassium is essential for regulating blood pressure. Lastly, increasing cholesterol intake is detrimental for hypertension as it can contribute to cardiovascular issues and worsen the condition.
