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 nurse is reviewing the laboratory results for a client with a history of atherosclerosis and notes elevated cholesterol levels. Which statement by the client indicates the nurse should plan follow-up instruction on a low-cholesterol diet?

• A. ''I take an omega-3 supplement daily.''
• B. ''I cook my food with canola oil.''
• C. ''I eat three eggs for breakfast each morning.''
• D. ''I flavor my meat with lemon juice.''

Correct answer: C

Rationale: The correct answer is C. Eating three eggs daily increases cholesterol intake, which could exacerbate atherosclerosis. Omega-3 supplements, cooking with canola oil, and flavoring meat with lemon juice do not significantly impact cholesterol levels compared to consuming three eggs daily. Therefore, the nurse should focus on educating the client to reduce egg consumption to improve cholesterol levels.

3. What is the best position to measure the leg circumference of a client with bipedal edema?

• A. Dorsal recumbent
• B. Sitting
• C. Standing
• D. Supine

Correct answer: A

Rationale: When measuring the leg circumference of a client with bipedal edema, the best position to ensure accurate and consistent measurements is the dorsal recumbent position. This position allows the legs to be comfortably positioned, with the individual lying on their back and legs extended. This facilitates accurate measurement of the circumference without the influence of gravity. Sitting and standing positions may not provide optimal conditions for accurate leg circumference measurements as they may not allow the legs to be fully extended. The supine position, although similar to dorsal recumbent, may not provide the same level of comfort and accuracy in leg circumference measurement for a client with bipedal edema.

4. Determining nursing care priorities is a 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: B

Rationale: Corrected Rationale: Planning in nursing involves setting priorities based on the identified patient needs, establishing goals, and developing a plan of care. Evaluation involves assessing the effectiveness of the care provided, implementation is the phase where the care plan is carried out, and assessment is the initial step of collecting data to identify the patient's needs. Therefore, in the context of determining nursing care priorities, the correct step is Planning (choice B).

5. 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.
