1. Which of the following is a chronic lung disease that includes conditions such as chronic bronchitis and emphysema, characterized by obstructed airflow from the lungs?

• A. Chronic obstructive pulmonary disease (COPD)
• B. Pulmonary fibrosis
• C. Asthma
• D. Pneumonia

Correct answer: A

Rationale: The correct answer is A, Chronic obstructive pulmonary disease (COPD). COPD is a chronic lung disease that encompasses conditions like chronic bronchitis and emphysema. These conditions lead to obstructed airflow from the lungs, causing symptoms such as cough, shortness of breath, and wheezing. Choice B, Pulmonary fibrosis, involves scarring of the lung tissue, leading to breathing difficulties but is not specifically characterized by obstructed airflow like COPD. Asthma (Choice C) is a chronic condition characterized by airway inflammation and bronchoconstriction, not always resulting in obstructed airflow. Pneumonia (Choice D) is an acute infection of the lung tissue, causing symptoms like fever, cough, and difficulty breathing, but is not a chronic condition like COPD.

2. This is a branch of the left coronary arteries which supplies the LEFT ATRIUM, posterior lateral surface of the left ventricle.

• A. Right coronary artery
• B. Left circumflex artery
• C. Left anterior descending artery
• D. Posterior descending artery

Correct answer: B

Rationale: The correct answer is B, Left circumflex artery. The circumflex artery is a branch of the left coronary artery that supplies blood to the left atrium and the lateral wall of the left ventricle. Choice A, the Right coronary artery, does not supply the mentioned areas. Choice C, the Left anterior descending artery, supplies the anterior wall of the left ventricle. Choice D, the Posterior descending artery, is a branch of the right coronary artery and supplies the inferior wall of the left ventricle and the posterior septum.

3. What are the pressure-sensitive structures located in the aortic and carotid bodies called?

• A. Baroreceptors
• B. Chemoreceptors
• C. Nociceptors
• D. Mechanoreceptors

Correct answer: A

Rationale: Baroreceptors are the correct answer. Baroreceptors are specialized sensory receptors that detect changes in pressure within blood vessels. They are primarily located in the aortic arch and carotid sinuses, where they play a crucial role in regulating blood pressure. Chemoreceptors (Choice B) are receptors that detect chemical changes, not pressure changes. Nociceptors (Choice C) are responsible for detecting painful stimuli. Mechanoreceptors (Choice D) respond to mechanical stimuli such as touch, pressure, and vibration, but they are not specifically located in the aortic and carotid bodies.

4. Which condition is characterized by chronic inflammation of the airways resulting in excess mucus production, leading to frequent coughing and breathing difficulties?

• A. Chronic bronchitis
• B. Asthma
• C. Pneumonia
• D. COPD

Correct answer: A

Rationale: The correct answer is A, Chronic bronchitis. Chronic bronchitis involves long-term inflammation of the bronchi, leading to excessive mucus production, frequent coughing, and breathing difficulties. Asthma (B) is characterized by reversible airway obstruction and bronchospasms. Pneumonia (C) is an infection of the lungs caused by bacteria, viruses, or fungi. COPD (D) is a term used to describe chronic lung diseases that cause airflow blockage and breathing-related problems.

5. The client on furosemide (Lasix) is complaining of muscle cramps. What electrolyte imbalance should the nurse suspect?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypocalcemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D, Hypokalemia. Muscle cramps are a common symptom of hypokalemia, an electrolyte imbalance characterized by low potassium levels. Furosemide, a loop diuretic like Lasix, can lead to potassium loss in the body, contributing to hypokalemia. Choice A, Hyperkalemia, is incorrect as it refers to high potassium levels. Choice B, Hyponatremia, is incorrect as it pertains to low sodium levels. Choice C, Hypocalcemia, is incorrect as it relates to low calcium levels, not typically associated with muscle cramps in the context of furosemide use.
