Cardiovascular System Exam Questions And Answers
1. What is a surgical procedure to replace a damaged or diseased heart valve with a prosthetic valve?
- A. Valve replacement
- B. Angioplasty
- C. Stent placement
- D. Bypass surgery
Correct answer: A
Rationale: Valve replacement is the correct answer because it involves replacing a damaged or diseased heart valve with a prosthetic valve. This procedure is essential for improving blood flow and heart function. Angioplasty (choice B) is a procedure to widen narrowed or obstructed arteries. Stent placement (choice C) involves inserting a mesh tube to help support weak arteries. Bypass surgery (choice D) is a procedure to create new routes for blood flow when arteries are blocked.
2. The client on spironolactone (Aldactone) has a potassium level of 5.6 mEq/L. What is the nurse’s priority action?
- A. Hold the spironolactone and notify the healthcare provider.
- B. Administer potassium supplements.
- C. Continue the spironolactone as ordered.
- D. Increase the dose of spironolactone.
Correct answer: A
Rationale: The correct answer is A: Hold the spironolactone and notify the healthcare provider. A potassium level of 5.6 mEq/L is high, indicating hyperkalemia. Spironolactone is a potassium-sparing diuretic that can further elevate potassium levels. Therefore, the priority action is to withhold the medication to prevent exacerbating hyperkalemia and notify the healthcare provider for further management. Option B is incorrect because administering potassium supplements would worsen the hyperkalemia. Option C is incorrect as continuing spironolactone can lead to a further increase in potassium levels. Option D is incorrect as increasing the dose of spironolactone would be inappropriate in the presence of elevated potassium levels.
3. Which type of heart valve disease occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium?
- A. Mitral regurgitation
- B. Aortic stenosis
- C. Tricuspid regurgitation
- D. Pulmonary hypertension
Correct answer: A
Rationale: Mitral regurgitation is the correct answer. It occurs when the mitral valve does not close properly, allowing blood to flow backward into the left atrium. This condition can lead to symptoms such as fatigue, shortness of breath, and if left untreated, it can progress to heart failure. Aortic stenosis (choice B) is a different heart valve condition characterized by narrowing of the aortic valve, restricting blood flow from the heart. Tricuspid regurgitation (choice C) involves the tricuspid valve not closing properly, leading to blood flowing back into the right atrium. Pulmonary hypertension (choice D) is a condition characterized by high blood pressure in the arteries of the lungs.
4. What is the term for inflammation of the bronchial tubes, often leading to a persistent cough and mucus production?
- A. Bronchitis
- B. Asthma
- C. Pneumonia
- D. Cystic fibrosis
Correct answer: A
Rationale: The correct answer is 'Bronchitis.' Bronchitis refers to the inflammation of the bronchial tubes, which can be acute or chronic, leading to symptoms like coughing and increased mucus production. Choice B, 'Asthma,' is a chronic condition characterized by inflammation and narrowing of the airways, often causing wheezing and shortness of breath. Choice C, 'Pneumonia,' is an infection that inflames air sacs in one or both lungs, leading to symptoms like fever, cough, and difficulty breathing. Choice D, 'Cystic fibrosis,' is a genetic disorder that affects the lungs and digestive system, causing mucus buildup and respiratory issues.
5. Which artery supplies the right atrium, right ventricle, a portion of the septum, SA node, AV node, and inferior portion of the left ventricle?
- A. Right coronary artery
- B. Left circumflex artery
- C. Posterior descending artery
- D. Aortic artery
Correct answer: A
Rationale: The correct answer is the right coronary artery. It supplies essential areas of the heart, including the right atrium, right ventricle, a portion of the septum, SA node, AV node, and the inferior portion of the left ventricle. The left circumflex artery primarily supplies the left atrium and lateral wall of the left ventricle, not the mentioned areas. The posterior descending artery supplies the inferior wall of the left ventricle, not the right side. The aortic artery is a general term and does not specifically refer to an artery that supplies the mentioned areas.
