Physical Exam Cardiovascular System
1. Which of the following is a chronic inflammatory disease of the airways that causes episodes of wheezing, breathlessness, chest tightness, and coughing?
- A. Asthma
- B. Bronchitis
- C. Pneumonia
- D. Emphysema
Correct answer: A
Rationale: Asthma is the correct answer. It is a chronic inflammatory disease of the airways characterized by episodes of wheezing, breathlessness, chest tightness, and coughing. These symptoms are often triggered by allergens or exercise. Bronchitis is an inflammation of the bronchial tubes, but it is not typically chronic or involve the same triggers as asthma. Pneumonia is an infection of the lungs, and emphysema is a type of chronic obstructive pulmonary disease (COPD) often caused by smoking.
2. Which valve prevents backflow of blood into the right ventricle from the pulmonary artery?
- A. Pulmonary valve
- B. Aortic valve
- C. Tricuspid valve
- D. Mitral valve
Correct answer: A
Rationale: The correct answer is the Pulmonary valve. The Pulmonary valve prevents backflow of blood into the right ventricle from the pulmonary artery after it has been ejected. The Aortic valve (choice B) prevents backflow from the aorta into the left ventricle. The Tricuspid valve (choice C) prevents backflow of blood into the right atrium from the right ventricle. The Mitral valve (choice D) prevents backflow from the left ventricle into the left atrium.
3. What test measures the electrical activity of the heart to detect arrhythmias and other heart conditions?
- A. Electrocardiogram (ECG or EKG)
- B. Chest X-ray
- C. Stress test
- D. Arterial blood gas (ABG)
Correct answer: A
Rationale: An electrocardiogram (ECG or EKG) is used to measure the heart's electrical activity, aiding in the detection of arrhythmias and other heart conditions. Choice B, a chest X-ray, is not used to measure electrical activity but to visualize the structures of the chest. Choice C, a stress test, evaluates the heart's response to exertion and is not primarily focused on measuring electrical activity. Choice D, an arterial blood gas (ABG) test, is used to assess oxygen and carbon dioxide levels in the blood, not the heart's electrical activity.
4. What condition is characterized by the inflammation of the heart's outer lining, often causing chest pain and other symptoms?
- A. Pericarditis
- B. Endocarditis
- C. Myocarditis
- D. Valvular heart disease
Correct answer: A
Rationale: Pericarditis is the correct answer because it is the inflammation of the pericardium, the outer lining of the heart. This condition commonly presents with symptoms like chest pain. Endocarditis (choice B) is the inflammation of the inner lining of the heart chambers and valves. Myocarditis (choice C) is the inflammation of the heart muscle itself. Valvular heart disease (choice D) refers to various conditions affecting the heart valves, not specifically the outer lining of the heart.
5. The client on nitroglycerin complains of a headache. How does the nurse explain this?
- A. This is a normal side effect of nitroglycerin.
- B. This is an allergic reaction to nitroglycerin.
- C. This is an indication of overdose.
- D. This is a sign of heart failure.
Correct answer: A
Rationale: The correct answer is A: 'This is a normal side effect of nitroglycerin.' Headaches are a common side effect of nitroglycerin due to vasodilation. Choice B is incorrect because allergic reactions to nitroglycerin typically present with symptoms like rash, itching, or shortness of breath. Choice C is incorrect as an overdose of nitroglycerin would likely present with symptoms beyond just a headache. Choice D is incorrect because headaches related to nitroglycerin are not indicative of heart failure.
