Cardiovascular System Exam Questions
1. The client is on dobutamine. Adverse effects of Dobutrex (dobutamine) include the following: Select all that apply.
- A. Heart failure
- B. Bradycardia
- C. Tachycardia
- D. Respiratory distress
Correct answer: C
Rationale: The correct answer is C: Tachycardia. Dobutamine is a medication that primarily increases heart rate (tachycardia) and blood pressure. Therefore, the adverse effects of dobutamine include tachycardia. Choices A, B, and D are incorrect. Heart failure is not an adverse effect of dobutamine; in fact, it is used to treat heart failure by increasing heart contractility. Bradycardia (slow heart rate) is not an expected adverse effect of dobutamine, as it usually increases heart rate. Respiratory distress is not a common adverse effect of dobutamine.
2. Which of the following is a genetic disorder that causes thick, sticky mucus to build up in the lungs and digestive system, leading to severe respiratory and digestive problems?
- A. Cystic fibrosis
- B. Pulmonary fibrosis
- C. Pulmonary edema
- D. Bronchiectasis
Correct answer: A
Rationale: The correct answer is A, cystic fibrosis. Cystic fibrosis is a genetic disorder characterized by the buildup of thick, sticky mucus in the lungs and digestive system, resulting in severe respiratory and digestive issues. Choice B, pulmonary fibrosis, involves scarring and thickening of lung tissue, not excessive mucus production. Choice C, pulmonary edema, refers to fluid accumulation in the lungs, not mucus buildup. Choice D, bronchiectasis, is a condition where the airways in the lungs are damaged and widened, leading to chronic cough and sputum production, but it does not specifically involve the thick, sticky mucus characteristic of cystic fibrosis.
3. Which condition is an infection that inflames the air sacs in one or both lungs, which may fill with fluid?
- A. Pneumonia
- B. Bronchitis
- C. Tuberculosis
- D. Cystic fibrosis
Correct answer: A
Rationale: The correct answer is A, Pneumonia. Pneumonia is an infection that inflames the air sacs in the lungs, which may fill with fluid or pus, causing symptoms like cough, fever, and difficulty breathing. Bronchitis (choice B) is an inflammation of the bronchial tubes, not the air sacs in the lungs. Tuberculosis (choice C) is a bacterial infection that primarily affects the lungs but does not always cause fluid accumulation in the air sacs. Cystic fibrosis (choice D) is a genetic disorder that affects the lungs but does not directly cause inflammation of the air sacs with fluid.
4. What is a surgical procedure where a blood vessel is grafted to bypass a blocked coronary artery, improving blood flow to the heart muscle?
- A. Coronary artery bypass graft (CABG)
- B. Valve replacement
- C. Angioplasty
- D. Endarterectomy
Correct answer: A
Rationale: The correct answer is A: Coronary artery bypass graft (CABG). CABG involves grafting a blood vessel to bypass a blocked coronary artery, enhancing blood flow to the heart muscle. This procedure helps reduce the risk of heart attack by restoring proper blood circulation to the heart. Choice B, valve replacement, is a different surgical procedure that involves replacing damaged or dysfunctional heart valves. Choice C, angioplasty, is a minimally invasive procedure that uses a balloon to open narrowed or blocked blood vessels. Choice D, endarterectomy, is the surgical removal of plaque from the lining of an artery to improve blood flow.
5. What is the narrowing of the arteries due to the buildup of plaque, which can lead to heart attacks and strokes?
- A. Coronary artery disease
- B. Peripheral artery disease
- C. Aortic stenosis
- D. Mitral valve prolapse
Correct answer: A
Rationale: Coronary artery disease is the correct answer. It is the narrowing or blockage of the coronary arteries due to plaque buildup, which can lead to heart attacks and other cardiovascular issues. Choice B, Peripheral artery disease, involves the narrowing of arteries in the limbs, not specifically the coronary arteries. Choice C, Aortic stenosis, refers to the narrowing of the aortic valve opening, not the arteries. Choice D, Mitral valve prolapse, is a condition where the valve between the left atrium and left ventricle doesn't close properly, unrelated to arterial narrowing.
