1. What is the condition where the body's immune system attacks its tissues, causing inflammation and damage?

• A. Autoimmune disease
• B. Infectious disease
• C. Allergic reaction
• D. Degenerative disease

Correct answer: A

Rationale: The correct answer is A: Autoimmune disease. Autoimmune diseases occur when the body's immune system mistakenly attacks its own tissues, leading to inflammation and damage. This is different from infectious diseases (choice B), which are caused by pathogenic microorganisms, allergic reactions (choice C), which involve an exaggerated response of the immune system to harmless substances, and degenerative diseases (choice D), which are characterized by progressive deterioration of tissue or organs due to various factors.

2. What type of therapy delivers high concentrations of oxygen to the lungs?

• A. Oxygen therapy
• B. Ventilator therapy
• C. Mechanical ventilation
• D. CPAP therapy

Correct answer: A

Rationale: Oxygen therapy is the correct answer because it specifically refers to a treatment that delivers high concentrations of oxygen to the lungs. This therapy is used for patients who require additional oxygen due to conditions affecting their breathing. Ventilator therapy (B), mechanical ventilation (C), and CPAP therapy (D) involve different mechanisms and purposes than delivering high concentrations of oxygen to the lungs.

3. What is a device that delivers a fine spray of medication into the airways?

• A. Nebulizer
• B. Inhaler
• C. Oxygen concentrator
• D. Peak flow meter

Correct answer: A

Rationale: A nebulizer is a device that converts liquid medication into a fine mist, allowing it to be inhaled directly into the lungs. This makes it the correct answer to the question. Choice B, an inhaler, delivers medication in a different form - as a pressurized dose that needs to be inhaled. Choice C, an oxygen concentrator, is used to deliver oxygen to patients with breathing difficulties but does not deliver medication. Choice D, a peak flow meter, is used to measure how fast air can be blown out of the lungs and is not involved in delivering medication.

4. 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.

5. Which type of lung cancer begins in the cells lining the bronchi and bronchioles?

• A. Adenocarcinoma
• B. Small cell lung cancer
• C. Squamous cell carcinoma
• D. Mesothelioma

Correct answer: A

Rationale: Adenocarcinoma is the correct answer because it is a type of lung cancer that originates in the cells lining the bronchi and bronchioles. Adenocarcinoma is one of the most common types of lung cancer, often found in non-smokers and more frequently in women. Small cell lung cancer (Choice B) typically starts in the bronchi, but it is characterized by its rapid growth and tendency to spread quickly. Squamous cell carcinoma (Choice C) usually begins in the squamous cells lining the bronchi and is strongly associated with smoking. Mesothelioma (Choice D) is a cancer that affects the lining of certain organs like the lungs, often caused by asbestos exposure, but it does not specifically start in the cells lining the bronchi and bronchioles.
