1. What is a chronic lung disease that includes chronic bronchitis and emphysema?

• A. Chronic Obstructive Pulmonary Disease (COPD)
• B. Pneumonia
• C. Asthma
• D. Tuberculosis

Correct answer: A

Rationale: The correct answer is Chronic Obstructive Pulmonary Disease (COPD). COPD is a chronic lung condition that encompasses chronic bronchitis and emphysema, causing airflow obstruction from the lungs. Pneumonia (choice B) is an infection in the lungs, while asthma (choice C) is characterized by airway inflammation and constriction. Tuberculosis (choice D) is a bacterial infection that primarily affects the lungs but is distinct from COPD.

2. What is the ability of cardiac cells to respond to an impulse by contracting?

• A. Excitability
• B. Contractility
• C. Rhythmicity
• D. Conductivity

Correct answer: A

Rationale: Excitability is the correct term that describes the ability of cardiac cells to respond to an impulse by contracting. Excitability refers to the cell's ability to respond to stimuli and generate an action potential. Choice B, Contractility, is incorrect as it refers to the ability of cardiac cells to contract after receiving a stimulus, not the response to the impulse itself. Choice C, Rhythmicity, is incorrect as it pertains to the heart's ability to contract rhythmically without external stimulation. Choice D, Conductivity, is incorrect as it refers to the ability of cardiac cells to transmit an impulse from cell to cell, not the direct response to the impulse by contracting.

3. What is a condition where blood clots form in the deep veins, usually in the legs, and can travel to the lungs, causing serious complications?

• A. Deep vein thrombosis (DVT)
• B. Pulmonary embolism
• C. Varicose veins
• D. Peripheral artery disease

Correct answer: A

Rationale: The correct answer is A, Deep vein thrombosis (DVT). Deep vein thrombosis occurs when blood clots form in the deep veins, usually in the legs, and these clots can potentially travel to the lungs, leading to a pulmonary embolism. Pulmonary embolism (choice B) is a serious complication that can result from untreated DVT. Varicose veins (choice C) and peripheral artery disease (choice D) are not directly related to the formation of blood clots in deep veins that can lead to pulmonary embolism.

4. Which type of medication helps to reduce the workload on the heart by slowing down the heart rate?

• A. Beta-blocker
• B. Calcium channel blocker
• C. Diuretic
• D. ACE inhibitor

Correct answer: A

Rationale: Beta-blockers are medications that work by blocking the action of hormones like adrenaline, thereby reducing the heart rate and the workload on the heart. This makes them effective in managing high blood pressure and various heart conditions. Calcium channel blockers work by relaxing blood vessels and reducing the heart's workload, but they do not primarily slow down the heart rate. Diuretics help the body get rid of excess salt and water by increasing urine production, which can lower blood pressure but not by slowing down the heart rate. ACE inhibitors work by relaxing blood vessels, not by directly affecting heart rate.

5. What is a genetic disorder that affects the lungs and digestive system, leading to thick, sticky mucus that can clog the airways?

• A. Cystic fibrosis
• B. COPD
• C. Bronchiectasis
• D. Pulmonary fibrosis

Correct answer: A

Rationale: The correct answer is A, cystic fibrosis. Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. It leads to the production of thick, sticky mucus that can clog the airways, causing respiratory issues. Choice B, COPD (Chronic Obstructive Pulmonary Disease), is a different condition usually caused by smoking or exposure to irritants. Choice C, bronchiectasis, involves the widening and scarring of the airways, not the production of thick mucus. Choice D, pulmonary fibrosis, is a lung disease characterized by scarring of the lung tissue, not excessive mucus production.
