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 is diagnosed with pericarditis. When assessing the client, the nurse is unable to auscultate a friction rub. Which action should the nurse implement?

• A. Notify the healthcare provider
• B. Document that the pericarditis has resolved
• C. Ask the client to lean forward and listen again
• D. Prepare to insert a unilateral chest tube

Correct answer: C

Rationale: The correct action for the nurse to implement when unable to auscultate a pericardial friction rub in a client diagnosed with pericarditis is to ask the client to lean forward and listen again. Leaning forward can help bring the heart closer to the chest wall, making it easier to detect the rub. Option A (Notifying the healthcare provider) is incorrect because further assessment is needed before escalating the situation. Option B (Documenting that the pericarditis has resolved) is incorrect as the absence of a friction rub does not necessarily mean resolution. Option D (Preparing to insert a unilateral chest tube) is incorrect as this intervention is not indicated for the absence of a friction rub.

3. Which of the following is a specialized medical treatment and teaching facility that provides general and specialized medical and dental care and treatment?

• A. CONUS
• B. MEDCEN
• C. MEDCOM
• D. MEDDAC

Correct answer: B

Rationale: The correct answer is B, MEDCEN, which stands for Medical Center. A MEDCEN is a specialized medical treatment and teaching facility that provides general and specialized medical and dental care and treatment. Choices A, C, and D are incorrect. CONUS refers to the continental United States and is not a medical facility. MEDCOM stands for Medical Command, which is an organization rather than a specific facility for medical treatment. MEDDAC stands for Medical Department Activity and is also an organization responsible for medical care delivery, not a specific treatment facility.

4. The nurse cares for a client receiving furosemide (Lasix). The nurse determines that teaching is effective if the client selects which of the following foods?

• A. One medium baked potato
• B. One slice of white bread
• C. One medium apple
• D. One scrambled egg

Correct answer: A

Rationale: The correct answer is A: One medium baked potato. Potatoes are high in potassium, which is essential for clients on Lasix to prevent hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, so consuming potassium-rich foods like baked potatoes can help maintain normal potassium levels. Choices B, C, and D do not provide a significant source of potassium, which is crucial for clients on furosemide therapy.

5. A 31-year-old client is seeking contraceptive information. Before responding to the client’s questions about contraceptives, the nurse obtains a health history. What factor in the client’s history indicates to the nurse that oral contraceptives are contraindicated?

• A. More than 30 years of age
• B. Had two multiple pregnancies
• C. Smokes 1 pack of cigarettes a day
• D. Has a history of borderline hypertension

Correct answer: C

Rationale: The correct answer is C. Smoking, especially in clients over 30, increases the risk of thromboembolic events, making oral contraceptives contraindicated. Choice A is incorrect as age alone is not a contraindication for oral contraceptives. Choice B is incorrect as having multiple pregnancies is not a contraindication for oral contraceptives. Choice D is incorrect as borderline hypertension is not a strict contraindication for oral contraceptives.
