Cardiovascular System Exam Questions Pdf

1. What is a device that delivers a fine spray of medication into the airways?

Correct answer: A

Rationale: A nebulizer is a device that converts liquid medication into a fine mist, allowing it to be inhaled directly into the lungs. This makes it the correct answer to the question. Choice B, an inhaler, delivers medication in a different form - as a pressurized dose that needs to be inhaled. Choice C, an oxygen concentrator, is used to deliver oxygen to patients with breathing difficulties but does not deliver medication. Choice D, a peak flow meter, is used to measure how fast air can be blown out of the lungs and is not involved in delivering medication.

2. Which valve prevents backflow of blood into the right ventricle from the pulmonary artery?

Correct answer: A

Rationale: The correct answer is the Pulmonary valve. The Pulmonary valve prevents backflow of blood into the right ventricle from the pulmonary artery after it has been ejected. The Aortic valve (choice B) prevents backflow from the aorta into the left ventricle. The Tricuspid valve (choice C) prevents backflow of blood into the right atrium from the right ventricle. The Mitral valve (choice D) prevents backflow from the left ventricle into the left atrium.

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

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. Which condition is characterized by the narrowing or blockage of arteries that supply blood to the heart by plaque?

Correct answer: A

Rationale: The correct answer is A, Coronary artery disease (CAD). CAD specifically refers to the condition where the arteries supplying blood to the heart become narrowed or blocked by plaque buildup. Choice B, Atherosclerosis, is a general term for the hardening and narrowing of arteries due to plaque buildup but does not specifically mention the heart. Choice C, Peripheral artery disease, involves narrowing of arteries that supply blood to areas other than the heart. Choice D, Congestive heart failure, is a condition where the heart is unable to pump blood effectively but is not primarily caused by narrowed or blocked arteries.

5. Which condition is characterized by chest pain due to reduced blood flow to the heart muscle?

Correct answer: A

Rationale: The correct answer is A, Angina. Angina is chest pain or discomfort caused by reduced blood flow to the heart muscle, often due to coronary artery disease. Choice B, Myocardial infarction, involves the death of heart muscle tissue due to a lack of blood supply, presenting with symptoms similar to angina but more severe. Pericarditis (Choice C) is inflammation of the pericardium, the sac surrounding the heart, which may cause chest pain but is not primarily due to reduced blood flow. Arrhythmia (Choice D) refers to abnormal heart rhythms but is not directly related to chest pain due to reduced blood flow.
