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. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?
- A. Peripheral artery disease
- B. Raynaud's disease
- C. Varicose veins
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
3. When administering enoxaparin (Lovenox) to a client for DVT prophylaxis, what is the most important lab value to monitor?
- A. Platelet count
- B. PT/INR
- C. aPTT
- D. Hemoglobin
Correct answer: A
Rationale: The correct answer is A: Platelet count. When administering enoxaparin (Lovenox) for DVT prophylaxis, it is crucial to monitor the platelet count as enoxaparin can lead to thrombocytopenia, a decrease in platelet levels. Monitoring the platelet count helps in early detection of this potential adverse effect. Choices B, C, and D are incorrect because PT/INR, aPTT, and hemoglobin levels are not the most important lab values to monitor specifically for enoxaparin administration and DVT prophylaxis.
4. A client on a beta blocker has a blood pressure of 90/60 mm Hg. What is the nurse’s priority action?
- A. Hold the beta blocker and notify the healthcare provider.
- B. Administer the beta blocker as ordered.
- C. Administer a diuretic to reduce blood pressure.
- D. Continue to monitor the client and reassess in 30 minutes.
Correct answer: A
Rationale: The correct answer is to hold the beta blocker and notify the healthcare provider. A blood pressure of 90/60 mm Hg is already low, and beta blockers can further decrease blood pressure. Administering the beta blocker can potentially worsen the situation, leading to complications. Administering a diuretic or continuing to monitor the client without taking immediate action could delay necessary intervention. Therefore, holding the beta blocker and involving the healthcare provider promptly is crucial in this scenario.
5. 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.
