Cardiovascular System Exam Questions And Answers

1. Which heart chamber receives oxygenated blood from the lungs and pumps it to the rest of the body?

Correct answer: C

Rationale: The correct answer is the left ventricle. It receives oxygenated blood from the left atrium and pumps it to the rest of the body through the aorta. The left atrium receives oxygenated blood from the lungs, the right atrium receives deoxygenated blood from the body, and the right ventricle pumps deoxygenated blood to the lungs.

2. What is a condition where the heart's mitral valve does not close properly, causing blood to leak backward into the left atrium?

Correct answer: A

Rationale: Mitral valve prolapse is the correct answer. It occurs when the mitral valve does not close properly, leading to blood leaking backward into the left atrium. This condition can manifest with symptoms such as palpitations and chest pain. Choices B, C, and D are incorrect because aortic stenosis involves narrowing of the aortic valve, mitral stenosis is the narrowing of the mitral valve, and tricuspid regurgitation is when blood leaks backward through the tricuspid valve.

3. What is a procedure to remove fluid or air from the pleural space to help a patient breathe easier?

Correct answer: A

Rationale: Correct! Thoracentesis is the correct answer. It is a procedure where fluid or air is removed from the pleural space in the chest to help the patient breathe more easily. Bronchoscopy (choice B) is a procedure to visualize the airways, while Chest X-ray (choice C) and CT scan (choice D) are imaging tests and do not involve the removal of fluid or air from the pleural space.

4. The client is given an alpha agonist. What might it be used for?

Correct answer: A

Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.

5. What is the condition where the lung collapses due to air leaking into the space between the lung and chest wall?

Correct answer: A

Rationale: Pneumothorax is the correct answer. It is the collapse of a lung due to air leaking into the space between the lung and chest wall. This condition often requires emergency treatment. Choice B, Pleural effusion, is the buildup of excess fluid between the layers of the pleura outside the lung, not air. Choice C, Pulmonary fibrosis, is a lung disease characterized by scarring and thickening of lung tissue, not related to lung collapse. Choice D, Lung cancer, is the uncontrolled growth of abnormal cells in the lung, not directly causing lung collapse.
