Cardiovascular System Exam Questions
1. What is the condition where the pericardium, the sac surrounding the heart, becomes inflamed, leading to chest pain and other symptoms?
- A. Pericarditis
- B. Myocarditis
- C. Endocarditis
- D. Pulmonary hypertension
Correct answer: A
Rationale: Pericarditis is the correct answer. It is the inflammation of the pericardium, the sac surrounding the heart, which can lead to chest pain and other symptoms. Myocarditis (choice B) is inflammation of the heart muscle, not the pericardium. Endocarditis (choice C) is inflammation of the inner lining of the heart chambers and valves, not the pericardium. Pulmonary hypertension (choice D) is high blood pressure in the arteries of the lungs, not related to pericardial inflammation.
2. What type of heart disease is characterized by the heart muscle becoming enlarged and weakened, reducing its ability to pump blood effectively?
- A. Dilated cardiomyopathy
- B. Hypertrophic cardiomyopathy
- C. Restrictive cardiomyopathy
- D. Myocarditis
Correct answer: A
Rationale: The correct answer is A: Dilated cardiomyopathy. Dilated cardiomyopathy is a type of heart disease where the heart muscle becomes enlarged and weakened, reducing its ability to pump blood effectively, which can lead to heart failure. Hypertrophic cardiomyopathy (B) is characterized by abnormal thickening of the heart muscle, not enlargement. Restrictive cardiomyopathy (C) involves the heart muscle becoming stiff and less flexible, limiting its ability to fill with blood properly. Myocarditis (D) is inflammation of the heart muscle, which can affect the heart's function but is different from dilated cardiomyopathy.
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. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?
- A. Increase the dose of warfarin.
- B. Administer vitamin K.
- C. Hold the warfarin and notify the healthcare provider.
- D. Monitor the client’s INR closely.
Correct answer: D
Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.
5. Which of the following is a chronic respiratory disease characterized by the irreversible obstruction of airflow?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary edema
- D. Bronchiectasis
Correct answer: A
Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic respiratory disease where the airflow in the lungs becomes obstructed, making it difficult to breathe. Choice B, Asthma, is a different chronic respiratory condition characterized by reversible airflow obstruction and airway hyperresponsiveness. Choice C, Pulmonary edema, is a condition where fluid accumulates in the lungs, leading to difficulty in breathing but not irreversible airflow obstruction. Choice D, Bronchiectasis, is a condition characterized by abnormal widening of the bronchial tubes, leading to recurrent respiratory infections, but it is not specifically defined by irreversible airflow obstruction.
