Nursing Elites

1. What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?

• A. Aortic aneurysm
• B. Arterial stenosis
• C. Pulmonary embolism
• D. Deep vein thrombosis

Correct answer: A

Rationale: An aortic aneurysm is a condition characterized by the weakening and bulging of the aorta, the body's main artery. If left untreated, this bulging may lead to a rupture, causing severe complications. Arterial stenosis refers to the narrowing of an artery, not the weakening and bulging seen in an aortic aneurysm. Pulmonary embolism involves a blockage in the pulmonary artery, which is different from the weakening and bulging in an aortic aneurysm. Deep vein thrombosis is the formation of a blood clot in a deep vein, not related to the condition described in the question.

2. The client is receiving intravenous dopamine. What is the most important nursing assessment?

• A. Monitor heart rate and rhythm
• B. Monitor blood pressure
• C. Monitor respiratory rate
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The correct answer is to monitor heart rate and rhythm when a client is receiving intravenous dopamine. Dopamine is known to potentially cause arrhythmias, making this assessment crucial. While monitoring blood pressure, respiratory rate, and oxygen saturation are important nursing assessments, they are not the most critical when dopamine is being administered.

3. What procedure uses a balloon to open narrowed or blocked blood vessels in the heart?

• A. Angioplasty
• B. Coronary artery bypass graft
• C. Stent placement
• D. Valve replacement

Correct answer: A

Rationale: The correct answer is Angioplasty. Angioplasty is a procedure that involves using a balloon to open narrowed or blocked blood vessels in the heart, thereby improving blood flow. This choice is correct because it directly matches the description provided in the question. Choices B, C, and D are incorrect because they involve different procedures: Bypass graft is a surgical procedure to redirect blood flow, stent placement involves inserting a mesh tube to keep an artery open, and valve replacement is the surgical replacement of a heart valve.

4. What is the condition where the blood flow through the coronary arteries is reduced or blocked, leading to chest pain or heart attack?

• A. Coronary artery disease
• B. Atherosclerosis
• C. Pulmonary embolism
• D. Pulmonary hypertension

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD occurs when the coronary arteries are narrowed or blocked, reducing blood flow to the heart muscle and increasing the risk of chest pain or heart attack. Choice B, Atherosclerosis, is a condition characterized by the hardening and narrowing of arteries due to the buildup of plaque. Choices C and D, Pulmonary embolism and Pulmonary hypertension, involve issues related to the lungs and not the coronary arteries.

5. What structure separates the left and right sides of the heart?

• A. Interventricular septum
• B. Endocardium
• C. Epicardium
• D. Pericardium

Correct answer: A

Rationale: The interventricular septum is the correct answer as it is the wall that separates the left and right sides of the heart, ensuring the oxygenated and deoxygenated blood do not mix. The endocardium is the inner lining of the heart chambers, the epicardium is the outermost layer of the heart wall, and the pericardium is the sac that surrounds the heart, providing protection and anchoring the heart in place. Therefore, choices B, C, and D are incorrect in the context of separating the left and right sides of the heart.
