1. What procedure involves inserting a needle into the pleural space to remove excess fluid and help the patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Spirometry
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to remove excess fluid, aiding in easier breathing. Bronchoscopy (Choice B) is a procedure to visualize the airways and diagnose lung problems, not specifically for fluid drainage. Spirometry (Choice C) is a test to measure lung function, not a procedure for fluid removal. Arterial blood gas (ABG) (Choice D) is a blood test to assess oxygen and carbon dioxide levels in the blood, not a procedure for draining fluid from the pleural space.

2. What test evaluates the heart's response to physical stress, often involving exercise on a treadmill while monitoring the heart?

• A. Stress test
• B. Echocardiogram
• C. Holter monitor
• D. CT angiography

Correct answer: A

Rationale: A stress test, also known as an exercise stress test, evaluates the heart's response to physical stress by monitoring its activity during exercise, typically on a treadmill. This test helps assess the heart's performance, detect coronary artery disease, and evaluate the effectiveness of heart treatments. Echocardiogram (choice B) is an ultrasound of the heart that provides detailed images of the heart's structure and function, but it does not involve physical stress like a stress test. Holter monitor (choice C) is a device for continuously monitoring the heart's rhythm and rate over a period (usually 24-48 hours), not during exercise. CT angiography (choice D) is a diagnostic test that uses X-rays to visualize blood vessels but does not involve physical stress like a stress test.

3. The nurse is caring for a client on warfarin with an INR of 1.8. What is the most appropriate action?

• A. Increase the dose of warfarin.
• B. Administer vitamin K.
• C. Hold the warfarin and notify the healthcare provider.
• D. Monitor the client’s INR closely.

Correct answer: D

Rationale: An INR of 1.8 is below the therapeutic range for a client on warfarin, indicating the need for monitoring closely to ensure that the INR levels reach the desired therapeutic range. Increasing the dose of warfarin (Choice A) without proper monitoring may lead to an increased risk of bleeding. Administering vitamin K (Choice B) is not typically recommended unless the client is experiencing major bleeding or requires rapid reversal of warfarin's effects. Holding the warfarin and notifying the healthcare provider (Choice C) may be necessary in certain situations, but the immediate action in this case should be to monitor the client's INR closely to guide further management.

4. What condition is characterized by narrowed or blocked arteries in the legs or arms, leading to pain and mobility issues?

• A. Peripheral artery disease
• B. Atherosclerosis
• C. Raynaud's disease
• D. Varicose veins

Correct answer: A

Rationale: The correct answer is A: Peripheral artery disease (PAD). PAD is a condition where the arteries in the legs or arms become narrowed or blocked, leading to pain and mobility issues. Choice B, Atherosclerosis, refers to the buildup of fats, cholesterol, and other substances in and on the artery walls, not specifically the narrowing or blockage in the extremities. Choice C, Raynaud's disease, is characterized by reduced blood flow to the extremities, leading to coldness, numbness, and color changes in the skin, but it is not primarily about narrowed or blocked arteries. Choice D, Varicose veins, involves enlarged, twisted veins usually in the legs, but it is not related to narrowed or blocked arteries causing pain and mobility issues.

5. What is the condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, causing pain and difficulty walking?

• A. Peripheral artery disease
• B. Raynaud's disease
• C. Varicose veins
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A, Peripheral artery disease (PAD). PAD is a condition where the blood vessels that supply blood to the legs and feet become narrowed or blocked, leading to decreased blood flow, pain, and difficulty walking, especially during physical activity. Raynaud's disease (choice B) is characterized by vasospasms in the fingers and toes, causing them to turn white or blue. Varicose veins (choice C) are enlarged, twisted veins usually found in the legs. Pulmonary embolism (choice D) is a blockage in one of the pulmonary arteries in the lungs, often caused by a blood clot.
