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 works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

2. What is the combat health support system in the field designed to do?

• A. Provide evacuation to the far rear for treatment and delay return to duty
• B. Project, sustain, and protect the health of the soldier in war and operations other than war
• C. Provide rearward evacuation and reassignment
• D. Provide far rear area care and delayed return to duty

Correct answer: B

Rationale: The correct answer is B. The combat health support system in the field is designed to project, sustain, and protect the health of soldiers in both war and operations other than war. Choice A is incorrect because the system is not primarily focused on providing evacuation to the far rear for treatment, but rather on overall health support. Choice C is incorrect as it only mentions rearward evacuation and reassignment, which is a limited scope compared to the comprehensive support provided by the system. Choice D is incorrect as it narrowly focuses on far rear area care and delayed return to duty, missing the broader aspects of health support and protection.

3. 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. Increased sodium intake (choice A) is not recommended as it can raise blood pressure. Decreasing potassium intake (choice B) is not advisable as potassium helps regulate blood pressure. Increased cholesterol intake (choice D) is also not recommended as high cholesterol levels can contribute to cardiovascular issues, including hypertension.

4. A patient with a history of peptic ulcer disease should avoid which medication?

• A. Acetaminophen
• B. Antacids
• C. Nonsteroidal anti-inflammatory drugs
• D. Antihistamines

Correct answer: C

Rationale: Patients with a history of peptic ulcer disease should avoid nonsteroidal anti-inflammatory drugs (NSAIDs) because they can worsen peptic ulcers. NSAIDs inhibit the production of prostaglandins, which help protect the stomach lining. Acetaminophen (Choice A) is a safer alternative for pain relief in patients with peptic ulcers. Antacids (Choice B) can actually help in symptom relief by neutralizing stomach acid. Antihistamines (Choice D) are not known to worsen peptic ulcers and are generally safe for use in patients with this condition.

5. 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.
