Cardiovascular System Exam Questions Pdf
1. What is the abnormal accumulation of fluid in the pleural space, often associated with infections or malignancies?
- A. Pleural effusion
- B. Pneumothorax
- C. Pulmonary edema
- D. Atelectasis
Correct answer: A
Rationale: The correct answer is A, pleural effusion. Pleural effusion is the accumulation of excess fluid between the layers of the pleura outside the lungs, often caused by infections, cancer, or other diseases. Pneumothorax (choice B) is the presence of air in the pleural space, not fluid. Pulmonary edema (choice C) is the accumulation of fluid in the lungs' air sacs and tissue, not in the pleural space. Atelectasis (choice D) is the collapse or closure of a lung resulting in reduced or absent gas exchange.
2. What is the narrowing of the arteries due to the buildup of plaque, which can lead to heart attacks and strokes?
- A. Coronary artery disease
- B. Peripheral artery disease
- C. Aortic stenosis
- D. Mitral valve prolapse
Correct answer: A
Rationale: Coronary artery disease is the correct answer. It is the narrowing or blockage of the coronary arteries due to plaque buildup, which can lead to heart attacks and other cardiovascular issues. Choice B, Peripheral artery disease, involves the narrowing of arteries in the limbs, not specifically the coronary arteries. Choice C, Aortic stenosis, refers to the narrowing of the aortic valve opening, not the arteries. Choice D, Mitral valve prolapse, is a condition where the valve between the left atrium and left ventricle doesn't close properly, unrelated to arterial narrowing.
3. 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.
4. The client is on warfarin and has an INR of 1.5. What is the nurse’s priority action?
- A. Increase the dose of warfarin.
- B. Hold the next dose of warfarin.
- C. Continue the current dose of warfarin.
- D. Monitor the client’s INR closely.
Correct answer: B
Rationale: An INR of 1.5 is below the therapeutic range for a client on warfarin, indicating that the client may be at risk of clot formation. The nurse's priority action should be to hold the next dose of warfarin to prevent further reduction of the INR. Increasing the dose could potentially lead to an increased risk of bleeding, and continuing the current dose may not be sufficient to bring the INR within the therapeutic range. Monitoring the client's INR closely is important but not the priority action in this scenario.
5. The client is receiving digoxin and has a potassium level of 2.8 mEq/L. What is the nurse’s priority action?
- A. Hold the digoxin and notify the healthcare provider.
- B. Increase the dose of digoxin.
- C. Continue the current dose of digoxin.
- D. Administer potassium supplements.
Correct answer: A
Rationale: The correct answer is to hold the digoxin and notify the healthcare provider. A potassium level of 2.8 mEq/L indicates hypokalemia, which can increase the risk of digoxin toxicity. Holding the medication and informing the healthcare provider is crucial to prevent adverse effects. Choice B is incorrect because increasing the dose of digoxin would further raise the risk of toxicity. Choice C is incorrect as continuing the current dose could exacerbate the toxicity risk. Choice D is incorrect because administering potassium supplements alone is not sufficient to address the potential digoxin toxicity; the first step should be to hold the digoxin and seek further guidance.
