1. What test measures the oxygen level in the blood, often used to monitor patients with respiratory or cardiovascular conditions?

• A. Pulse oximetry
• B. Arterial blood gas (ABG)
• C. Echocardiogram
• D. Chest X-ray

Correct answer: A

Rationale: The correct answer is A, Pulse oximetry. Pulse oximetry is a non-invasive test that measures the oxygen saturation level in the blood, commonly used to monitor respiratory and cardiovascular health. Arterial blood gas (ABG) measures the levels of oxygen and carbon dioxide in the blood, providing more detailed information than pulse oximetry. Echocardiogram is an ultrasound test used to visualize the heart's structure and function, while a chest X-ray is used to visualize the structures in the chest, such as the heart, lungs, and bones.

2. The client is on spironolactone (Aldactone). What is the most important dietary instruction?

• A. Avoid foods high in potassium.
• B. Increase intake of foods high in potassium.
• C. Avoid foods high in sodium.
• D. Increase intake of foods high in sodium.

Correct answer: A

Rationale: The correct answer is to avoid foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium and can lead to hyperkalemia if too much potassium is consumed. Choices B, C, and D are incorrect because increasing intake of potassium-rich foods can worsen hyperkalemia, while avoiding foods high in sodium is not the primary concern when taking spironolactone.

3. What is a condition characterized by an abnormal buildup of fluid between the layers of tissue lining the lungs and chest cavity?

• A. Pleural effusion
• B. Pulmonary edema
• C. Atelectasis
• D. Sarcoidosis

Correct answer: A

Rationale: Pleural effusion is the correct answer as it refers to the accumulation of excess fluid between the layers of the pleura surrounding the lungs and chest cavity. This condition can be caused by various factors such as infections, heart failure, or cancer. Pulmonary edema (choice B) involves fluid accumulation in the lungs' air sacs and is not specific to the pleura. Atelectasis (choice C) is the collapse or closure of a lung leading to airless lung tissue and is not related to fluid buildup. Sarcoidosis (choice D) is a condition characterized by the growth of tiny collections of inflammatory cells in different parts of the body, not specifically involving fluid accumulation in the pleural space.

4. What is a surgical procedure to remove one of the lobes of the lungs, often performed to treat lung cancer?

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

Correct answer: A

Rationale: A lobectomy is the correct answer. This surgical procedure involves removing one of the lobes of the lungs, commonly done to treat lung cancer or other serious lung ailments. Choice B, pneumonectomy, involves the complete removal of a lung, not just a lobe. Choice C, thoracotomy, is a surgical incision into the chest wall and is not specific to removing a lung lobe. Choice D, tracheostomy, is the creation of an opening in the windpipe to assist with breathing and is unrelated to lung lobe removal.

5. 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.
