Cardiovascular System Exam Questions And Answers
1. What condition is characterized by the inflammation of the pleura, causing sharp chest pain that worsens with breathing?
- A. Pleurisy
- B. Pericarditis
- C. Endocarditis
- D. Myocarditis
Correct answer: A
Rationale: The correct answer is Pleurisy. Pleurisy is the inflammation of the pleura, the lining surrounding the lungs, which causes sharp chest pain that worsens with breathing. Pericarditis (choice B) is the inflammation of the pericardium, the sac around the heart, which typically causes chest pain that worsens when lying down. Endocarditis (choice C) is the inflammation of the inner lining of the heart chambers and valves, leading to symptoms like fever, fatigue, and abnormal heart sounds. Myocarditis (choice D) is inflammation of the heart muscle, which can cause symptoms such as chest pain, fatigue, and shortness of breath.
2. The client is given an alpha agonist. What might it be used for?
- A. For hemostasis
- B. To dilate the arteries
- C. To dilate the veins
- D. To decrease afterload
Correct answer: A
Rationale: Alpha agonists are used for hemostasis to help control bleeding by constricting blood vessels, leading to decreased blood flow to the area. Choices B, C, and D are incorrect as alpha agonists do not typically dilate arteries, dilate veins, or decrease afterload.
3. What is the procedure where a small mesh tube is inserted into an artery to keep it open after angioplasty?
- A. Stent placement
- B. Bypass surgery
- C. Angioplasty
- D. Valve replacement
Correct answer: A
Rationale: The correct answer is A, stent placement. Stent placement involves inserting a small mesh tube into an artery to maintain its openness after angioplasty. This choice is correct because it directly describes the procedure mentioned in the question. Choices B, C, and D are incorrect. Bypass surgery involves rerouting blood flow around a blocked artery using a vessel from another part of the body. Angioplasty is the procedure of widening a narrowed or blocked blood vessel, often followed by stent placement. Valve replacement is a surgical procedure to replace a damaged or diseased heart valve with an artificial or biological valve.
4. Which condition is characterized by the sudden onset of shortness of breath, often occurring at night and associated with heart failure?
- A. Paroxysmal nocturnal dyspnea
- B. Sleep apnea
- C. Orthopnea
- D. Dyspnea
Correct answer: A
Rationale: Paroxysmal nocturnal dyspnea is the correct answer. It is characterized by the sudden onset of shortness of breath during sleep, often associated with heart failure. Choice B, Sleep apnea, involves pauses in breathing during sleep but is not specifically associated with heart failure. Choice C, Orthopnea, is difficulty breathing that occurs when lying down and is relieved by sitting up, not necessarily associated with heart failure. Choice D, Dyspnea, is a general term for difficulty breathing and does not specifically describe the sudden onset at night associated with heart failure as seen in paroxysmal nocturnal dyspnea.
5. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?
- A. Pneumonia
- B. Tuberculosis
- C. Asthma
- D. Bronchitis
Correct answer: A
Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.
