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. The client on amiodarone reports shortness of breath. What is the nurse’s best response?
- A. Notify the healthcare provider immediately.
- B. Reassure the client that this is a common side effect.
- C. Instruct the client to monitor their symptoms at home.
- D. Suggest the client reduce physical activity.
Correct answer: A
Rationale: When a client on amiodarone reports shortness of breath, it can be indicative of pulmonary toxicity, a severe side effect associated with this medication. The nurse's priority is to notify the healthcare provider immediately to assess the situation and determine the appropriate course of action. Choice B is incorrect because shortness of breath with amiodarone should not be dismissed as a common side effect. Instructing the client to monitor symptoms at home (Choice C) may delay necessary intervention. Suggesting the client reduce physical activity (Choice D) does not address the potential serious nature of the symptom and the need for prompt evaluation.
3. Which heart chamber receives oxygenated blood from the four pulmonary veins and serves as a reservoir during ventricular systole?
- A. Right atrium
- B. Left atrium
- C. Right ventricle
- D. Left ventricle
Correct answer: B
Rationale: The correct answer is B, Left atrium. The left atrium receives oxygenated blood from the lungs via the four pulmonary veins and acts as a holding chamber before the blood is pumped into the left ventricle. Choice A, Right atrium, is incorrect as it receives deoxygenated blood from the body via the vena cava. Choices C and D, Right ventricle and Left ventricle, are incorrect as they receive blood from the atria, not the pulmonary veins.
4. Which type of lung cancer is strongly associated with exposure to asbestos?
- A. Mesothelioma
- B. Adenocarcinoma
- C. Squamous cell carcinoma
- D. Small cell lung cancer
Correct answer: A
Rationale: The correct answer is Mesothelioma. This type of lung cancer is indeed strongly associated with exposure to asbestos, affecting the lining of the lungs or abdomen. Adenocarcinoma, Squamous cell carcinoma, and Small cell lung cancer are not primarily linked to asbestos exposure, making them incorrect choices for this question.
5. What is a surgical procedure to remove one of the lobes of the lungs, often performed to treat lung cancer?
- A. Lobectomy
- B. Pneumonectomy
- C. Thoracotomy
- D. Tracheostomy
Correct answer: A
Rationale: A lobectomy is the correct answer. This surgical procedure involves removing one of the lobes of the lungs, commonly done to treat lung cancer or other serious lung ailments. Choice B, pneumonectomy, involves the complete removal of a lung, not just a lobe. Choice C, thoracotomy, is a surgical incision into the chest wall and is not specific to removing a lung lobe. Choice D, tracheostomy, is the creation of an opening in the windpipe to assist with breathing and is unrelated to lung lobe removal.
