Cardiovascular System Exam Questions Pdf
1. What procedure involves using a catheter to create a small scar in the heart tissue to block abnormal electrical signals and restore normal heart rhythm?
- A. Catheter ablation
- B. Angioplasty
- C. Stent placement
- D. Valve replacement
Correct answer: A
Rationale: Catheter ablation is the correct answer. During catheter ablation, a catheter is used to create a small scar in the heart tissue to block abnormal electrical signals, thereby restoring a normal heart rhythm. Choices B, C, and D are incorrect because angioplasty is a procedure to widen narrowed or obstructed arteries, stent placement involves inserting a mesh tube to support a weak artery, and valve replacement is the surgical procedure of replacing a heart valve, none of which match the description provided in the question.
2. The client on furosemide (Lasix) has a potassium level of 3.1 mEq/L. What is the nurse’s priority action?
- A. Administer a potassium supplement.
- B. Hold the furosemide and notify the healthcare provider.
- C. Continue the current dose of furosemide.
- D. Administer Digibind.
Correct answer: A
Rationale: The correct answer is to administer a potassium supplement. A potassium level of 3.1 mEq/L indicates hypokalemia, which can lead to serious complications like cardiac dysrhythmias. Therefore, the priority action is to address the low potassium level by administering a potassium supplement. Holding the furosemide (Choice B) may be necessary in the long term to prevent further potassium loss, but the immediate need is to correct the low potassium level. Continuing the current dose of furosemide (Choice C) without addressing the low potassium level can worsen hypokalemia. Administering Digibind (Choice D) is not indicated for low potassium levels; Digibind is used to treat digoxin toxicity.
3. What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?
- A. Pneumonia
- B. Bronchitis
- C. Tuberculosis
- D. Asthma
Correct answer: A
Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.
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. This is a type of lung disease that results from the inhalation of certain dusts, often in the workplace, leading to lung damage.
- A. Pneumoconiosis
- B. Asbestosis
- C. Silicosis
- D. Anthracosis
Correct answer: A
Rationale: Pneumoconiosis is the correct answer. It is a lung disease caused by inhaling certain types of dust, commonly in a workplace setting, resulting in lung damage. Asbestosis (choice B) is a specific type of pneumoconiosis caused by asbestos fibers. Silicosis (choice C) is another type of pneumoconiosis caused by inhaling crystalline silica dust. Anthracosis (choice D) is a condition characterized by the accumulation of coal dust particles in the lungs, not necessarily resulting in lung damage.
