1. What is a condition where the heart beats too fast, reducing its ability to pump blood effectively?

• A. Tachycardia
• B. Bradycardia
• C. Arrhythmia
• D. Ventricular fibrillation

Correct answer: A

Rationale: Tachycardia is the correct answer because it is a condition characterized by a fast heart rate, which can decrease the heart's efficiency in pumping blood. Bradycardia, on the other hand, refers to a slow heart rate, which is the opposite of what is described in the question. Arrhythmia is a general term for any irregularity in the heart's rhythm, not necessarily specifically related to a fast heart rate. Ventricular fibrillation is a life-threatening arrhythmia where the heart's lower chambers quiver instead of pumping blood effectively, but it is not specifically characterized by a fast heart rate.

2. What is a condition where the airways become inflamed and narrow, making breathing difficult?

• A. Asthma
• B. Bronchitis
• C. Pleurisy
• D. Tuberculosis

Correct answer: A

Rationale: Asthma is the correct answer. It is a condition characterized by inflammation, narrowing, and swelling of the airways, leading to symptoms like wheezing, shortness of breath, and coughing. Bronchitis is the inflammation of the bronchial tubes; Pleurisy is inflammation of the tissues that line the lungs and chest cavity; Tuberculosis is a bacterial infection that mainly affects the lungs.

3. What is a condition where the lung's air sacs become inflamed and fill with fluid or pus, causing cough, fever, chills, and difficulty breathing?

• A. Pneumonia
• B. Tuberculosis
• C. Asthma
• D. Bronchitis

Correct answer: A

Rationale: Pneumonia is the correct answer. It is an infection that inflames the air sacs in one or both lungs, leading to the accumulation of fluid or pus, which results in symptoms such as cough, fever, chills, and difficulty breathing. Tuberculosis (choice B) is a bacterial infection affecting the lungs but does not typically cause the same acute symptoms as described. Asthma (choice C) is a chronic respiratory condition characterized by inflammation and narrowing of the airways, not specifically involving the air sacs. Bronchitis (choice D) is an inflammation of the bronchial tubes, not the air sacs in the lungs, and does not typically cause the same symptoms as pneumonia.

4. 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.

5. What procedure involves inserting a needle into the pleural space to remove excess fluid and help the patient breathe more easily?

• A. Thoracentesis
• B. Bronchoscopy
• C. Spirometry
• D. Arterial blood gas (ABG)

Correct answer: A

Rationale: Thoracentesis is the correct answer. It is a procedure where a needle is inserted into the pleural space to remove excess fluid, aiding in easier breathing. Bronchoscopy (Choice B) is a procedure to visualize the airways and diagnose lung problems, not specifically for fluid drainage. Spirometry (Choice C) is a test to measure lung function, not a procedure for fluid removal. Arterial blood gas (ABG) (Choice D) is a blood test to assess oxygen and carbon dioxide levels in the blood, not a procedure for draining fluid from the pleural space.
