Nursing Elites

1. Which of the following is a rare but serious condition where the pulmonary arteries become narrowed, increasing the blood pressure in the lungs?

• A. Pulmonary hypertension
• B. Pulmonary embolism
• C. Pulmonary fibrosis
• D. Aortic stenosis

Correct answer: A

Rationale: The correct answer is A, Pulmonary hypertension. Pulmonary hypertension is a rare but serious condition characterized by high blood pressure in the arteries of the lungs, which can lead to heart failure. Pulmonary embolism (choice B) involves a blockage in one of the pulmonary arteries in the lungs. Pulmonary fibrosis (choice C) is a lung disease that causes lung tissue scarring. Aortic stenosis (choice D) is a condition where the aortic valve narrows, affecting blood flow from the heart.

2. The nurse is monitoring a client on dobutamine. What adverse effect should the nurse watch for?

• A. Tachycardia
• B. Bradycardia
• C. Hypertension
• D. Respiratory distress

Correct answer: A

Rationale: The correct answer is A: Tachycardia. Dobutamine is a medication that stimulates beta-1 adrenergic receptors in the heart, leading to increased heart rate. Therefore, tachycardia is a common adverse effect that the nurse should monitor for. Choices B, C, and D are incorrect because dobutamine typically does not cause bradycardia, hypertension, or respiratory distress as its primary adverse effects.

3. The nurse is caring for a client on warfarin with an INR of 5.2. What is the most appropriate action?

• A. Administer vitamin K as an antidote.
• B. Hold the next dose of warfarin.
• C. Increase the dose of warfarin.
• D. Monitor the client’s INR closely.

Correct answer: A

Rationale: An INR of 5.2 is elevated, indicating an increased risk of bleeding. Administering vitamin K can help reverse the effects of warfarin, which is the most appropriate action in this situation. Holding the next dose of warfarin is not enough to address the high INR, and increasing the dose would further elevate the INR level. Monitoring the INR closely is important, but in this case, immediate action is needed to counteract the anticoagulant effects of warfarin.

4. This is a procedure where a small mesh tube is inserted into an artery to keep it open and improve blood flow.

• A. Stent placement
• B. Angioplasty
• C. Bypass surgery
• D. Coronary artery bypass graft (CABG)

Correct answer: A

Rationale: Stent placement is a procedure where a small mesh tube (stent) is inserted into an artery to keep it open and improve blood flow, often following angioplasty.

5. The client is on spironolactone (Aldactone). What is the most important dietary instruction?

• A. Avoid foods high in potassium.
• B. Increase intake of foods high in potassium.
• C. Avoid foods high in sodium.
• D. Increase intake of foods high in sodium.

Correct answer: A

Rationale: The correct answer is to avoid foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if too much potassium is consumed. Choices B, C, and D are incorrect because increasing intake of potassium-rich foods can worsen hyperkalemia, while avoiding foods high in sodium is not the primary concern when taking spironolactone.
