1. What is a condition characterized by the presence of air or gas in the pleural space, leading to the collapse of the lung?
- A. Pneumothorax
- B. Pulmonary embolism
- C. Pleural effusion
- D. Atelectasis
Correct answer: A
Rationale: The correct answer is Pneumothorax. Pneumothorax occurs when air or gas accumulates in the pleural space, causing the lung to collapse. This condition can result in symptoms such as chest pain and difficulty breathing. Pulmonary embolism (choice B) is a blockage in one of the pulmonary arteries in the lungs, usually caused by a blood clot. Pleural effusion (choice C) is the accumulation of excess fluid in the pleural space, not air or gas. Atelectasis (choice D) refers to the collapse or closure of a lung resulting in reduced or absent gas exchange.
2. 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.
3. The nurse is administering digoxin to a client. What is the most important parameter to check before administration?
- A. Heart rate
- B. Blood pressure
- C. Respiratory rate
- D. Oxygen saturation
Correct answer: A
Rationale: The correct answer is A: Heart rate. Before administering digoxin, it is crucial to check the client's heart rate because digoxin can cause bradycardia, making it essential to ensure the heart rate is within the appropriate range. Blood pressure, respiratory rate, and oxygen saturation are also important parameters to monitor in a clinical setting, but when administering digoxin, the focus should primarily be on the heart rate due to its potential effects on cardiac function.
4. What is a surgical procedure where a blood vessel is grafted to bypass a blocked coronary artery, improving blood flow to the heart muscle?
- A. Coronary artery bypass graft (CABG)
- B. Valve replacement
- C. Angioplasty
- D. Endarterectomy
Correct answer: A
Rationale: The correct answer is A: Coronary artery bypass graft (CABG). CABG involves grafting a blood vessel to bypass a blocked coronary artery, enhancing blood flow to the heart muscle. This procedure helps reduce the risk of heart attack by restoring proper blood circulation to the heart. Choice B, valve replacement, is a different surgical procedure that involves replacing damaged or dysfunctional heart valves. Choice C, angioplasty, is a minimally invasive procedure that uses a balloon to open narrowed or blocked blood vessels. Choice D, endarterectomy, is the surgical removal of plaque from the lining of an artery to improve blood flow.
5. This heart condition is characterized by decreased cardiac output and tissue perfusion, which can lead to organ failure.
- A. Cardiogenic shock
- B. Myocardial infarction
- C. Endocarditis
- D. Pericarditis
Correct answer: A
Rationale: The correct answer is A: Cardiogenic shock. Cardiogenic shock is a severe condition characterized by the heart's inability to pump enough blood, leading to decreased cardiac output and tissue perfusion, which can result in organ failure. Choice B, Myocardial infarction, specifically refers to a blockage of blood flow to the heart muscle. Choices C and D, Endocarditis and Pericarditis, do not directly involve decreased cardiac output leading to organ failure, making them incorrect in the context of the symptoms described in the question.
