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. Which of the following drugs contribute to peptic ulcers?

• A. Antacids
• B. Certain antibiotics
• C. Cholesterol-lowering medications
• D. Nonsteroidal anti-inflammatory drugs

Correct answer: D

Rationale: The correct answer is D: Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs are known to contribute to peptic ulcers by affecting the gastric mucosa. Choice A, Antacids, actually help to alleviate symptoms of peptic ulcers by neutralizing stomach acid. Choice B, Certain antibiotics, are used to treat H. pylori infections, a common cause of peptic ulcers. Choice C, Cholesterol-lowering medications, do not contribute to peptic ulcers.

3. The nurse supervises care of a client in Buck’s traction. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)

• A. The nurse removes the foam boot three times per day to inspect the skin
• B. The staff turn the client to the unaffected side
• C. The staff turn the client to the unaffected side and the nurse asks the client to dorsiflex the foot on the affected leg
• D. The nurse asks the client to dorsiflex the foot on the affected leg

Correct answer: C

Rationale: Correct care for a client in Buck’s traction includes turning the client to the unaffected side to prevent complications such as pressure ulcers. Additionally, asking the client to dorsiflex the foot on the affected leg helps prevent foot drop. Removing the foam boot three times per day to inspect the skin is unnecessary and could disrupt the traction, so it is not appropriate. Therefore, choices A and D are incorrect.

4. Which of the following is a nonmedical member of a unit who receives additional training in providing care beyond basic first aid procedures?

• A. Area support squad leader
• B. ATLS specialist
• C. Tactical lifesaver
• D. Combat lifesaver

Correct answer: D

Rationale: The correct answer is D, 'Combat lifesaver.' A Combat Lifesaver is a nonmedical member of a unit who is trained in advanced first aid procedures, providing care beyond basic first aid. Choice A, 'Area support squad leader,' does not specifically refer to someone trained in providing advanced care. Choice B, 'ATLS specialist,' refers to someone trained in Advanced Trauma Life Support (ATLS), which is beyond the scope of the question. Choice C, 'Tactical lifesaver,' is not a recognized term for the role described in the question.

5. The nurse is analyzing laboratory values for the assigned clients. Which finding, based on the client's medical history, indicates the need for immediate follow-up?

• A. Client with chronic kidney disease and serum creatinine of 1.6 mg/dL
• B. Client with diabetes mellitus and a glycosylated hemoglobin A (HbA1c) of 7.0%
• C. Client with heart failure and a B-type natriuretic peptide (BNP) of 140 pg/mL
• D. Client who is male and has anemia with hemoglobin of 16.5 g/dL and hematocrit of 45%

Correct answer: B

Rationale: An HbA1c of 7.0% in a client with diabetes mellitus indicates poor long-term glucose control, necessitating immediate follow-up. Elevated HbA1c levels suggest a higher average blood sugar over the past 2-3 months, increasing the risk of complications associated with diabetes. Choices A, C, and D do not require immediate follow-up based solely on the provided information. A serum creatinine of 1.6 mg/dL in a client with chronic kidney disease, a BNP of 140 pg/mL in a client with heart failure, and hemoglobin of 16.5 g/dL and hematocrit of 45% in a male client with anemia are within acceptable ranges or do not indicate an urgent need for intervention.
