Cardiovascular System Exam Questions
1. What is the condition where the pericardium, the sac surrounding the heart, becomes inflamed, leading to chest pain and other symptoms?
- A. Pericarditis
- B. Myocarditis
- C. Endocarditis
- D. Pulmonary hypertension
Correct answer: A
Rationale: Pericarditis is the correct answer. It is the inflammation of the pericardium, the sac surrounding the heart, which can lead to chest pain and other symptoms. Myocarditis (choice B) is inflammation of the heart muscle, not the pericardium. Endocarditis (choice C) is inflammation of the inner lining of the heart chambers and valves, not the pericardium. Pulmonary hypertension (choice D) is high blood pressure in the arteries of the lungs, not related to pericardial inflammation.
2. In cases of myocardial infarction leading to shock, which medication is appropriate to counteract shock?
- A. Atropine
- B. Dopamine
- C. Digoxin
- D. Adenosine
Correct answer: B
Rationale: In cases of myocardial infarction leading to shock, dopamine is the drug of choice. Dopamine helps increase blood pressure and improve blood flow to vital organs, making it beneficial in managing shock. Atropine is mainly used for symptomatic bradycardia, not for shock. Digoxin is a cardiac glycoside used in heart failure and atrial fibrillation, not for managing shock. Adenosine is typically used for diagnosing and treating supraventricular tachycardias, not for shock associated with myocardial infarction.
3. Which artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart?
- A. Left anterior descending artery
- B. Left circumflex artery
- C. Posterior descending artery
- D. Aortic artery
Correct answer: A
Rationale: The correct answer is the Left anterior descending artery. This artery supplies the anterior wall of the left ventricle, the anterior interventricular septum, the anterior papillary muscles, and apex of the heart. The Left circumflex artery (choice B) supplies the lateral and posterior walls of the left ventricle, the posterior descending artery (choice C) supplies the inferior part of the heart, and the aortic artery (choice D) is not a specific coronary artery.
4. What is a chronic lung disease that includes chronic bronchitis and emphysema?
- A. Chronic Obstructive Pulmonary Disease (COPD)
- B. Pneumonia
- C. Asthma
- D. Tuberculosis
Correct answer: A
Rationale: The correct answer is Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung condition that encompasses chronic bronchitis and emphysema, causing airflow obstruction from the lungs. Pneumonia (choice B) is an infection in the lungs, while asthma (choice C) is characterized by airway inflammation and constriction. Tuberculosis (choice D) is a bacterial infection that primarily affects the lungs but is distinct from COPD.
5. Which of the following is a chronic respiratory disease characterized by the irreversible obstruction of airflow?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary edema
- D. Bronchiectasis
Correct answer: A
Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic respiratory disease where the airflow in the lungs becomes obstructed, making it difficult to breathe. Choice B, Asthma, is a different chronic respiratory condition characterized by reversible airflow obstruction and airway hyperresponsiveness. Choice C, Pulmonary edema, is a condition where fluid accumulates in the lungs, leading to difficulty in breathing but not irreversible airflow obstruction. Choice D, Bronchiectasis, is a condition characterized by abnormal widening of the bronchial tubes, leading to recurrent respiratory infections, but it is not specifically defined by irreversible airflow obstruction.
