Cardiovascular System Exam Questions Pdf
1. What is a condition where the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?
- A. Stroke
- B. Heart attack
- C. Pulmonary embolism
- D. Pneumonia
Correct answer: A
Rationale: A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to brain cell death and potential disability. Choice B, a heart attack, involves a blockage in the blood vessels that supply the heart muscle. Choice C, a pulmonary embolism, is a blockage in one of the pulmonary arteries in the lungs. Choice D, pneumonia, is an infection that inflames the air sacs in one or both lungs.
2. When administering furosemide (Lasix) to a client, which lab value is most important to monitor?
- A. Potassium
- B. Sodium
- C. Calcium
- D. Chloride
Correct answer: A
Rationale: When administering furosemide (Lasix), it is crucial to monitor potassium levels closely. Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Monitoring potassium levels helps prevent adverse effects associated with low potassium, such as cardiac arrhythmias. While monitoring sodium, calcium, and chloride levels may also be important in certain situations, potassium is the most critical to monitor when administering furosemide.
3. Which condition involves the enlargement and weakening of the left ventricle of the heart, leading to reduced pumping ability?
- A. Dilated cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Restrictive cardiomyopathy
- D. Pericarditis
Correct answer: A
Rationale: The correct answer is A: Dilated cardiomyopathy. Dilated cardiomyopathy is characterized by the enlargement and weakening of the left ventricle of the heart, which results in a reduced ability to pump blood effectively. Choice B, Hypertrophic cardiomyopathy, involves thickening of the heart muscle, not enlargement. Choice C, Restrictive cardiomyopathy, is characterized by stiffening of the heart muscle, not enlargement. Choice D, Pericarditis, refers to inflammation of the pericardium, the lining surrounding the heart, and does not involve enlargement and weakening of the left ventricle.
4. Which test measures the electrical activity of the heart and can detect arrhythmias and other heart conditions?
- A. Electrocardiogram (ECG or EKG)
- B. Chest X-ray
- C. MRI
- D. CT scan
Correct answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG or EKG). An electrocardiogram is a test that measures the electrical activity of the heart and can detect arrhythmias and other heart conditions by recording the heart's electrical impulses. Choices B, C, and D are incorrect because a chest X-ray is used to visualize the structures in the chest, an MRI (Magnetic Resonance Imaging) is used to provide detailed images of organs and tissues, and a CT scan (Computed Tomography) is a type of imaging that uses X-rays to create detailed cross-sectional images of the body.
5. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Bronchitis
Correct answer: A
Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.
