What is a chronic condition where the bronchial tubes in the lungs become inflamed and narrowed, often caused by smoking?
- A. Chronic bronchitis
- B. Emphysema
- C. Asthma
- D. Tuberculosis
Correct Answer: A
Rationale: The correct answer is A: Chronic bronchitis. Chronic bronchitis is characterized by inflammation and narrowing of the bronchial tubes, often caused by smoking. This condition leads to persistent coughing and mucus production. Emphysema (B) is a separate condition where the air sacs in the lungs are damaged, causing shortness of breath. Asthma (C) is a chronic respiratory condition characterized by airway inflammation and bronchospasms, triggered by various factors. Tuberculosis (D) is a bacterial infection that primarily affects the lungs, causing symptoms like coughing up blood and weight loss. Chronic bronchitis specifically relates to the inflammation and narrowing of the bronchial tubes due to smoking.

The client is given an alpha agonist. What might it be used for?
- A. For hemostasis
- B. To dilate the arteries
- C. To dilate the veins
- D. To decrease afterload
Correct Answer: A
Rationale: The correct answer is A: For hemostasis. Alpha agonists (such as epinephrine or norepinephrine) are used for hemostasis by causing vasoconstriction, which helps in stopping bleeding by constricting blood vessels.
Explanation for why other choices are incorrect:
B: To dilate the arteries - Alpha agonists actually cause vasoconstriction, not dilation of arteries.
C: To dilate the veins - Alpha agonists cause vasoconstriction, not dilation of veins.
D: To decrease afterload - While alpha agonists can increase blood pressure by vasoconstriction, they are not typically used specifically to decrease afterload.
The nurse is caring for a client on amiodarone who complains of visual disturbances. 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. Advise the client to monitor their symptoms at home.
- D. Suggest the client reduce physical activity.
Correct Answer: A
Rationale: The correct answer is A: Notify the healthcare provider immediately. Visual disturbances can be a sign of serious side effects of amiodarone, such as optic neuropathy. Promptly notifying the healthcare provider allows for timely evaluation and appropriate management.
Choice B is incorrect because visual disturbances with amiodarone are not common and should not be dismissed as such. Choice C is incorrect as self-monitoring may delay necessary medical intervention. Choice D is also incorrect as reducing physical activity does not address the underlying cause of visual disturbances and may not be necessary.
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: The correct answer is A: Coronary artery disease. This condition involves the narrowing of arteries supplying blood to the heart due to plaque buildup. Plaque can lead to blockages, causing heart attacks and strokes. Peripheral artery disease (B) affects arteries outside the heart. Aortic stenosis (C) is the narrowing of the aortic valve, not arteries. Mitral valve prolapse (D) is a condition affecting the mitral valve, not arteries. Therefore, A is the correct answer.
Which condition is characterized by the sudden onset of shortness of breath, often occurring at night and associated with heart failure?
- A. Paroxysmal nocturnal dyspnea
- B. Sleep apnea
- C. Orthopnea
- D. Dyspnea
Correct Answer: A
Rationale: The correct answer is A: Paroxysmal nocturnal dyspnea. This condition is characterized by sudden onset of shortness of breath at night, often associated with heart failure. It occurs when a person lies down due to fluid redistribution in the body, leading to increased pressure on the lungs and heart. Sleep apnea (B) is a separate condition characterized by pauses in breathing during sleep. Orthopnea (C) is difficulty breathing while lying flat, relieved by sitting up. Dyspnea (D) is a general term for shortness of breath but does not specifically refer to the sudden onset at night associated with heart failure.
Which test measures how much and how quickly you can move air out of your lungs?
- A. Spirometry
- B. Peak flow meter
- C. Lung volume test
- D. Arterial blood gas
Correct Answer: A
Rationale: Spirometry is the correct answer because it measures the volume of air exhaled in a specific time frame, assessing lung function and capacity. It is commonly used to diagnose conditions like asthma and COPD. Peak flow meter measures only the maximum speed of exhalation, not volume. Lung volume test measures the total lung capacity, not the speed of air movement. Arterial blood gas measures oxygen and carbon dioxide levels in the blood, not lung function.
