1. What is a procedure to remove fluid or air from the pleural space to help a patient breathe easier?

• A. Thoracentesis
• B. Bronchoscopy
• C. Chest X-ray
• D. CT scan

Correct answer: A

Rationale: Correct! Thoracentesis is the correct answer. It is a procedure where fluid or air is removed from the pleural space in the chest to help the patient breathe more easily. Bronchoscopy (choice B) is a procedure to visualize the airways, while Chest X-ray (choice C) and CT scan (choice D) are imaging tests and do not involve the removal of fluid or air from the pleural space.

2. The client on warfarin has an INR of 3.8. What is the most appropriate action by the nurse?

• A. Administer vitamin K.
• B. Hold the next dose of warfarin.
• C. Increase the dose of warfarin.
• D. Notify the healthcare provider immediately.

Correct answer: A

Rationale: An INR of 3.8 is elevated, indicating an increased risk of bleeding. Administering vitamin K can help reverse the effects of warfarin. Holding the next dose of warfarin would be appropriate if the INR was too high, but not as the first-line action. Increasing the dose of warfarin would worsen the situation by further increasing the INR. Notifying the healthcare provider is important, but immediate action to address the elevated INR is necessary.

3. Which condition involves the enlargement and weakening of the left ventricle of the heart, leading to reduced pumping ability?

• A. Dilated cardiomyopathy
• B. Hypertrophic cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Pericarditis

Correct answer: A

Rationale: The correct answer is A: Dilated cardiomyopathy. Dilated cardiomyopathy is characterized by the enlargement and weakening of the left ventricle of the heart, which results in a reduced ability to pump blood effectively. Choice B, Hypertrophic cardiomyopathy, involves thickening of the heart muscle, not enlargement. Choice C, Restrictive cardiomyopathy, is characterized by stiffening of the heart muscle, not enlargement. Choice D, Pericarditis, refers to inflammation of the pericardium, the lining surrounding the heart, and does not involve enlargement and weakening of the left ventricle.

4. What is a condition where the heart beats with an irregular or abnormal rhythm?

• A. Arrhythmia
• B. Hypertension
• C. Tachycardia
• D. Bradycardia

Correct answer: A

Rationale: Arrhythmia is the correct answer because it refers to an irregular or abnormal heart rhythm, which can cause the heart to beat too fast, too slow, or erratically. Hypertension (choice B) is high blood pressure and not directly related to irregular heart rhythm. Tachycardia (choice C) is a condition where the heart beats too quickly, not necessarily irregularly. Bradycardia (choice D) is a condition where the heart beats too slowly, not necessarily irregularly. Therefore, only arrhythmia (choice A) fits the description provided in the question.

5. 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.
