Nursing Elites

1. The client is on a nitrate for angina. What is the most common side effect the nurse should monitor for?

• A. Headache
• B. Flushing
• C. Dizziness
• D. Nausea

Correct answer: A

Rationale: The correct answer is A, Headache. Nitrates commonly cause headaches as a side effect due to vasodilation. Flushing, dizziness, and nausea are less common side effects associated with nitrates. Flushing is more related to the dilation of blood vessels closer to the skin's surface, dizziness could occur but is not as common as headaches, and nausea is a less typical side effect of nitrates.

2. What is the condition where the heart's mitral valve becomes narrowed, restricting blood flow from the left atrium to the left ventricle?

• A. Mitral stenosis
• B. Aortic stenosis
• C. Tricuspid regurgitation
• D. Pulmonary hypertension

Correct answer: A

Rationale: Mitral stenosis is the correct answer. It is a condition characterized by the narrowing of the heart's mitral valve, which hinders the flow of blood from the left atrium to the left ventricle. This obstruction can lead to symptoms such as shortness of breath and fatigue. Aortic stenosis (choice B) is the narrowing of the aortic valve, not the mitral valve. Tricuspid regurgitation (choice C) is the backflow of blood through the tricuspid valve, not narrowing. Pulmonary hypertension (choice D) is increased blood pressure in the pulmonary arteries, not narrowing of the mitral valve.

3. Which valve opens during ventricular systole and closes during ventricular diastole?

• A. Aortic valve
• B. Pulmonary valve
• C. Mitral valve
• D. Tricuspid valve

Correct answer: B

Rationale: The correct answer is B: Pulmonary valve. The pulmonary valve opens during ventricular systole to allow blood to flow from the right ventricle into the pulmonary artery. The aortic valve opens during ventricular systole to allow blood to flow from the left ventricle into the aorta. The mitral valve and tricuspid valve are atrioventricular valves that open during ventricular diastole to allow blood to flow from the atria into the ventricles.

4. What type of imaging test uses X-rays to visualize the blood vessels after injecting them with a contrast dye?

• A. Angiography
• B. CT scan
• C. MRI
• D. Ultrasound

Correct answer: A

Rationale: Angiography is the correct answer because it is an imaging test that specifically uses X-rays to visualize blood vessels by injecting them with a contrast dye. This procedure is crucial for diagnosing conditions such as blockages or aneurysms. The other options, CT scan, MRI, and ultrasound, do not involve the use of contrast dye to visualize blood vessels with X-rays.

5. What is a surgical procedure to replace a damaged or diseased heart valve with a prosthetic valve?

• A. Valve replacement
• B. Angioplasty
• C. Stent placement
• D. Bypass surgery

Correct answer: A

Rationale: Valve replacement is the correct answer because it involves replacing a damaged or diseased heart valve with a prosthetic valve. This procedure is essential for improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries. Stent placement (choice C) involves inserting a mesh tube to help support weak arteries. Bypass surgery (choice D) is a procedure to create new routes for blood flow when arteries are blocked.
