1. What procedure involves inserting a flexible tube with a light and camera into the airways to examine the lungs and collect samples?

• A. Bronchoscopy
• B. Thoracentesis
• C. Lung biopsy
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A: Bronchoscopy. Bronchoscopy is a procedure that entails inserting a flexible tube with a light and camera into the airways to examine the lungs and collect tissue or fluid samples. This procedure is commonly performed to diagnose lung conditions such as infections, tumors, or obstructions. Choice B, thoracentesis, involves inserting a needle into the pleural space to remove fluid for diagnostic or therapeutic purposes related to the lungs or pleura, not the airways. Choice C, lung biopsy, typically involves obtaining tissue samples from the lungs for further examination, not directly visualizing the airways. Choice D, chest X-ray, is a diagnostic imaging technique that uses radiation to create images of the chest area, providing a different type of information compared to bronchoscopy.

2. The client is on warfarin and has an INR of 1.5. What is the nurse’s priority action?

• A. Increase the dose of warfarin.
• B. Hold the next dose of warfarin.
• C. Continue the current dose of warfarin.
• D. Monitor the client’s INR closely.

Correct answer: B

Rationale: An INR of 1.5 is below the therapeutic range for a client on warfarin, indicating that the client may be at risk of clot formation. The nurse's priority action should be to hold the next dose of warfarin to prevent further reduction of the INR. Increasing the dose could potentially lead to an increased risk of bleeding, and continuing the current dose may not be sufficient to bring the INR within the therapeutic range. Monitoring the client's INR closely is important but not the priority action in this scenario.

3. What condition involves a weakened and bulging aorta, the main artery in the body, potentially leading to rupture?

• A. Aortic aneurysm
• B. Arterial stenosis
• C. Pulmonary embolism
• D. Deep vein thrombosis

Correct answer: A

Rationale: An aortic aneurysm is a condition characterized by the weakening and bulging of the aorta, the body's main artery. If left untreated, this bulging may lead to a rupture, causing severe complications. Arterial stenosis refers to the narrowing of an artery, not the weakening and bulging seen in an aortic aneurysm. Pulmonary embolism involves a blockage in the pulmonary artery, which is different from the weakening and bulging in an aortic aneurysm. Deep vein thrombosis is the formation of a blood clot in a deep vein, not related to the condition described in the question.

4. What is the amount of tension the ventricle must develop during contraction to eject blood from the left ventricle into the aorta?

• A. Afterload
• B. Preload
• C. Automaticity
• D. Ejection fraction

Correct answer: A

Rationale: Afterload is the correct answer because it refers to the pressure or tension that the ventricle must overcome during systole to eject blood into the aorta. Preload, on the other hand, is the degree of stretch of the ventricular muscle at the end of diastole before it contracts. Automaticity is the ability of the heart to generate electrical impulses independently, and ejection fraction is the percentage of blood pumped out of the ventricle with each heartbeat. Therefore, in the context of the question, afterload best describes the amount of tension the ventricle must develop to eject blood into the aorta.

5. This is a type of lung disease that results from the inhalation of certain dusts, often in the workplace, leading to lung damage.

• A. Pneumoconiosis
• B. Asbestosis
• C. Silicosis
• D. Anthracosis

Correct answer: A

Rationale: Pneumoconiosis is the correct answer. It is a lung disease caused by inhaling certain types of dust, commonly in a workplace setting, resulting in lung damage. Asbestosis (choice B) is a specific type of pneumoconiosis caused by asbestos fibers. Silicosis (choice C) is another type of pneumoconiosis caused by inhaling crystalline silica dust. Anthracosis (choice D) is a condition characterized by the accumulation of coal dust particles in the lungs, not necessarily resulting in lung damage.
