1. What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?

• A. Hypertension
• B. Hypotension
• C. Hyperlipidemia
• D. Hyperglycemia

Correct answer: A

Rationale: Hypertension, also known as high blood pressure, is a chronic condition characterized by persistently elevated pressure in the arteries. This condition increases the risk of heart disease, stroke, and other health issues. Hypotension (choice B) refers to low blood pressure and is not the correct answer. Hyperlipidemia (choice C) is high levels of fats in the blood, not related to blood pressure. Hyperglycemia (choice D) is high blood sugar levels, not directly related to elevated blood pressure.

2. What is a severe and often sudden allergic reaction that can lead to breathing difficulties and anaphylactic shock?

• A. Anaphylaxis
• B. Allergic rhinitis
• C. Bronchospasm
• D. Asthma attack

Correct answer: A

Rationale: Anaphylaxis is the correct answer. It is a severe allergic reaction that can result in difficulty breathing, a drop in blood pressure, and even anaphylactic shock if not treated promptly. Choice B, allergic rhinitis, is characterized by symptoms such as a runny or stuffy nose, sneezing, and itching. Choice C, bronchospasm, refers to the sudden constriction of the muscles in the walls of the bronchioles, leading to breathing difficulties. Choice D, asthma attack, involves the inflammation and narrowing of the airways, resulting in symptoms like wheezing, coughing, and chest tightness.

3. Which condition involves the enlargement and weakening of the left ventricle of the heart, leading to reduced pumping ability?

• A. Dilated cardiomyopathy
• B. Hypertrophic cardiomyopathy
• C. Restrictive cardiomyopathy
• D. Pericarditis

Correct answer: A

Rationale: The correct answer is A: Dilated cardiomyopathy. Dilated cardiomyopathy is characterized by the enlargement and weakening of the left ventricle of the heart, which results in a reduced ability to pump blood effectively. Choice B, Hypertrophic cardiomyopathy, involves thickening of the heart muscle, not enlargement. Choice C, Restrictive cardiomyopathy, is characterized by stiffening of the heart muscle, not enlargement. Choice D, Pericarditis, refers to inflammation of the pericardium, the lining surrounding the heart, and does not involve enlargement and weakening of the left ventricle.

4. 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.

5. Which term refers to the relaxation phase of the heart, during which the chambers fill with blood?

• A. Diastole
• B. Systole
• C. Refractoriness
• D. Automaticity

Correct answer: A

Rationale: The correct answer is A, Diastole. Diastole is the phase of the cardiac cycle when the heart muscles relax, allowing the chambers to fill with blood. Choice B, Systole, is incorrect as systole is the contraction phase of the heart when blood is pumped out of the chambers. Choice C, Refractoriness, refers to a period during which the heart muscle is unresponsive to stimuli. Choice D, Automaticity, relates to the heart's ability to generate its own electrical impulses.
