1. What is a surgical procedure to create an opening in the windpipe to assist with breathing?

• A. Tracheostomy
• B. Lobectomy
• C. Thoracotomy
• D. Pleurodesis

Correct answer: A

Rationale: Tracheostomy is the correct answer. It is a surgical procedure to create an opening in the windpipe (trachea) to assist with breathing. This procedure is commonly used for patients who require long-term ventilation support. Choice B, Lobectomy, involves the removal of a lobe of the lung and is not related to creating an opening in the windpipe. Choice C, Thoracotomy, is a surgical incision into the chest wall and is not specifically related to creating an opening in the windpipe. Choice D, Pleurodesis, is a procedure to treat recurrent pleural effusions by causing the pleural layers to stick together, and it is not related to creating an opening in the windpipe.

2. Which surgical procedure involves removing a portion of the lung?

• A. Lobectomy
• B. Pneumonectomy
• C. Tracheostomy
• D. Bronchoscopy

Correct answer: A

Rationale: A lobectomy is the surgical removal of a lobe of the lung. This procedure is commonly performed to treat conditions like lung cancer or severe lung diseases. Pneumonectomy involves removing an entire lung, making it incorrect. Tracheostomy is a surgical procedure to create an opening in the windpipe, not involving lung tissue removal. Bronchoscopy is a diagnostic procedure that allows visualization of the airways using a thin, flexible tube with a camera, not involving lung tissue removal.

3. What test measures the electrical activity of the heart over a 24- or 48-hour period?

• A. Holter monitor
• B. Electrocardiogram
• C. Stress test
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that continuously records the heart's electrical activity over 24 to 48 hours, aiding in the diagnosis of arrhythmias and other heart conditions. Choice B, an Electrocardiogram, provides a snapshot of the heart's electrical activity at a specific point in time, not over an extended period like a Holter monitor. Choice C, a Stress test, measures how the heart responds to physical activity and is not used for continuous monitoring of electrical activity. Choice D, a Chest X-ray, is used to visualize the structures of the chest, not to measure the heart's electrical activity.

4. 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.

5. What is the amount of blood the heart pumps through the circulatory system in a minute?

• A. Cardiac output
• B. Stroke volume
• C. End-diastolic volume
• D. Ejection fraction

Correct answer: A

Rationale: The correct answer is A: Cardiac output. Cardiac output is the volume of blood pumped by the heart per minute. It is calculated by multiplying the stroke volume (the amount of blood pumped out of the heart in each beat) by the heart rate (number of heartbeats per minute). This question specifically asks for the total amount of blood pumped through the circulatory system in a minute, which is represented by cardiac output. Choices B, C, and D are incorrect because stroke volume refers to the amount of blood pumped out of the heart in each beat, end-diastolic volume is the volume of blood in the heart at the end of diastole, and ejection fraction is the percentage of blood pumped out of the heart with each contraction, not the total amount pumped per minute.
