Cardiovascular System Exam Questions Pdf

1. What is the abnormal accumulation of fluid in the pleural space, often associated with infections or malignancies?

Correct answer: A

Rationale: The correct answer is A, pleural effusion. Pleural effusion is the accumulation of excess fluid between the layers of the pleura outside the lungs, often caused by infections, cancer, or other diseases. Pneumothorax (choice B) is the presence of air in the pleural space, not fluid. Pulmonary edema (choice C) is the accumulation of fluid in the lungs' air sacs and tissue, not in the pleural space. Atelectasis (choice D) is the collapse or closure of a lung resulting in reduced or absent gas exchange.

2. What test measures the electrical activity of the heart to detect arrhythmias and other heart conditions?

Correct answer: A

Rationale: An electrocardiogram (ECG or EKG) is used to measure the heart's electrical activity, aiding in the detection of arrhythmias and other heart conditions. Choice B, a chest X-ray, is not used to measure electrical activity but to visualize the structures of the chest. Choice C, a stress test, evaluates the heart's response to exertion and is not primarily focused on measuring electrical activity. Choice D, an arterial blood gas (ABG) test, is used to assess oxygen and carbon dioxide levels in the blood, not the heart's electrical activity.

3. Which condition is characterized by chronic inflammation of the airways resulting in excess mucus production, leading to frequent coughing and breathing difficulties?

Correct answer: A

Rationale: The correct answer is A, Chronic bronchitis. Chronic bronchitis involves long-term inflammation of the bronchi, leading to excessive mucus production, frequent coughing, and breathing difficulties. Asthma (B) is characterized by reversible airway obstruction and bronchospasms. Pneumonia (C) is an infection of the lungs caused by bacteria, viruses, or fungi. COPD (D) is a term used to describe chronic lung diseases that cause airflow blockage and breathing-related problems.

4. The nurse is giving a client an IV bolus of heparin. What is the most important nursing action?

Correct answer: A

Rationale: When administering an IV bolus of heparin, the most important nursing action is to monitor the client's heart rate. Heparin can cause bradycardia as a side effect, making it crucial to assess the heart rate for any abnormalities. Checking the blood pressure (Choice B) is important but not as critical as monitoring the heart rate. While checking for signs of bleeding (Choice C) is essential, it is not the most crucial action when administering heparin. Monitoring the respiratory rate (Choice D) is also important but not as directly related to the potential side effects of heparin as monitoring the heart rate.

5. Which heart chamber receives venous blood returning to the heart via the superior and inferior vena cava?

Correct answer: A

Rationale: The correct answer is A: Right atrium. The right atrium is the heart chamber that receives deoxygenated blood returning from the body via the superior and inferior vena cava. The blood enters the right atrium from the vena cava and then passes through the tricuspid valve into the right ventricle. Choices B, C, and D are incorrect because the left atrium receives oxygenated blood from the lungs, the right ventricle pumps blood to the lungs for oxygenation, and the left ventricle pumps oxygenated blood to the body.
