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. Identify the three layers of the heart:

• A. Endocardium, Myocardium, Epicardium
• B. Epicardium, Pericardium, Endocardium
• C. Myocardium, Endocardium, Pericardium
• D. Pericardium, Myocardium, Endocardium

Correct answer: A

Rationale: The correct answer is A: Endocardium, Myocardium, Epicardium. The heart consists of three main layers: the endocardium, which lines the inner chambers of the heart; the myocardium, the middle layer responsible for the heart's pumping action; and the epicardium, the outermost layer that protects the heart. Choices B, C, and D are incorrect as they do not list the heart's layers in the correct order or combination.

3. What is the condition where the heart's mitral valve becomes narrowed, restricting blood flow from the left atrium to the left ventricle?

• A. Mitral stenosis
• B. Aortic stenosis
• C. Tricuspid regurgitation
• D. Pulmonary hypertension

Correct answer: A

Rationale: Mitral stenosis is the correct answer. It is a condition characterized by the narrowing of the heart's mitral valve, which hinders the flow of blood from the left atrium to the left ventricle. This obstruction can lead to symptoms such as shortness of breath and fatigue. Aortic stenosis (choice B) is the narrowing of the aortic valve, not the mitral valve. Tricuspid regurgitation (choice C) is the backflow of blood through the tricuspid valve, not narrowing. Pulmonary hypertension (choice D) is increased blood pressure in the pulmonary arteries, not narrowing of the mitral valve.

4. What is the term used to describe a condition where the blood flow to the brain is temporarily interrupted, often referred to as a 'mini-stroke'?

• A. Transient ischemic attack (TIA)
• B. Stroke
• C. Myocardial infarction
• D. Pulmonary embolism

Correct answer: A

Rationale: The correct answer is A: Transient ischemic attack (TIA). A transient ischemic attack (TIA) is often called a 'mini-stroke' because it is characterized by a temporary interruption of blood flow to the brain, resulting in stroke-like symptoms that typically resolve within a short period. Choice B, 'Stroke,' is incorrect because a stroke involves a more prolonged interruption of blood flow, leading to lasting brain damage. Choices C and D, 'Myocardial infarction' and 'Pulmonary embolism,' are unrelated conditions involving the heart and lungs, respectively, and do not describe a temporary interruption of blood flow to the brain.

5. The nurse is caring for a client on digoxin. What is the most important assessment before administering this medication?

• A. Check the client’s heart rate.
• B. Check the client’s blood pressure.
• C. Check the client’s respiratory rate.
• D. Check the client’s oxygen saturation.

Correct answer: A

Rationale: The correct answer is to check the client’s heart rate before administering digoxin because one of the side effects of digoxin is bradycardia. Monitoring the heart rate is crucial to assess whether the client's heart rate is within the acceptable range before giving the medication. Checking the blood pressure (Choice B), respiratory rate (Choice C), or oxygen saturation (Choice D) are important assessments in general patient care, but they are not specifically related to the administration of digoxin.
