Cardiovascular System Exam Questions And Answers
1. What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?
- A. Chronic bronchitis
- B. Emphysema
- C. Asthma
- D. Tuberculosis
Correct answer: A
Rationale: Chronic bronchitis is the correct answer because it is a long-term condition characterized by inflammation and narrowing of the bronchial tubes in the lungs, commonly triggered by smoking. Emphysema involves damage to the air sacs in the lungs, not specifically the bronchial tubes. Asthma is a condition of reversible airway obstruction usually due to allergies or other triggers, not solely smoking. Tuberculosis is a bacterial infection that primarily affects the lungs but is not directly related to inflammation and narrowing of the bronchial tubes.
2. What is a condition where the blood flow to the brain is temporarily blocked, often referred to as a mini-stroke?
- A. Transient ischemic attack (TIA)
- B. Stroke
- C. Aneurysm
- D. Myocardial infarction
Correct answer: A
Rationale: A transient ischemic attack (TIA) is the correct answer. A TIA is often referred to as a mini-stroke because it is caused by a temporary blockage of blood flow to the brain. This blockage resolves on its own, typically within minutes to hours, leading to temporary symptoms similar to a stroke. Option B, 'Stroke,' is incorrect because a stroke involves a more prolonged interruption of blood flow to the brain. Option C, 'Aneurysm,' is incorrect as it is a bulge in a blood vessel that can rupture and cause bleeding, not a temporary blockage of blood flow. Option D, 'Myocardial infarction,' is also incorrect as it refers to a heart attack, not a condition involving the brain's blood flow.
3. The client is being taught about the use of warfarin. What is the most important dietary instruction?
- A. Avoid foods high in vitamin K.
- B. Increase the intake of vitamin K-rich foods.
- C. Avoid foods high in protein.
- D. Increase the intake of foods high in calcium.
Correct answer: A
Rationale: The correct answer is A: Avoid foods high in vitamin K. Warfarin is a medication that works by decreasing the activity of vitamin K in the body to prevent blood clotting. Therefore, consuming foods high in vitamin K like green leafy vegetables can interfere with the medication's effectiveness. Choices B, C, and D are incorrect. Increasing the intake of vitamin K-rich foods would counteract the effects of warfarin. Avoiding foods high in protein or increasing the intake of foods high in calcium are not specifically related to the use of warfarin.
4. The client is on enalapril (Vasotec) for hypertension. What side effect is most commonly associated with this medication?
- A. Dry cough
- B. Hypotension
- C. Hyperkalemia
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Dry cough. A dry cough is a common side effect of ACE inhibitors like enalapril. ACE inhibitors can cause the accumulation of bradykinin, leading to irritation of the respiratory tract and resulting in a persistent dry cough. Hypotension (choice B) is a possible side effect of ACE inhibitors but is less common than a dry cough. Hyperkalemia (choice C) is another side effect of ACE inhibitors, but it is not the most commonly associated one. Headache (choice D) is not a common side effect of enalapril compared to a dry cough. Therefore, the most commonly associated side effect with enalapril is a dry cough.
5. What is a procedure to remove fluid or air from the pleural space to help a patient breathe easier?
- A. Thoracentesis
- B. Bronchoscopy
- C. Chest X-ray
- D. CT scan
Correct answer: A
Rationale: Correct! Thoracentesis is the correct answer. It is a procedure where fluid or air is removed from the pleural space in the chest to help the patient breathe more easily. Bronchoscopy (choice B) is a procedure to visualize the airways, while Chest X-ray (choice C) and CT scan (choice D) are imaging tests and do not involve the removal of fluid or air from the pleural space.
