The most common cause of coronary artery disease is
Myocarditis
Hypoglycemia
Atherosclerosis
Vasospasm
The Correct Answer is C
Atherosclerosis is a condition where the walls of the arteries become thick and hard due to the accumulation of fatty deposits, cholesterol, and other substances. Over time, these deposits can build up and narrow the arteries, reducing blood flow to the heart muscle. This can lead to the development of coronary artery disease, which is a condition where the heart muscle does not get enough oxygen and nutrients to function properly. The narrowing of the arteries can also increase the risk of blood clots, which can lead to a heart attack or stroke.
Myocarditis is an inflammation of the heart muscle, usually caused by a viral infection, and is not the most common cause of coronary artery disease.
Hypoglycemia is a condition where the blood sugar level is too low, and it is not directly related to the development of coronary artery disease.
Vasospasm is a sudden constriction of a blood vessel, which can lead to reduced blood flow and tissue damage. It can contribute to the development of coronary artery disease, but it is not the most common cause.

Correct Answer is D
Explanation
Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) that is characterized by inflammation and narrowing of the bronchial tubes, which can lead to symptoms such as cough, shortness of breath, and wheezing. The primary cause of chronic bronchitis is smoking, and the most effective way to halt its progression is by quitting smoking.
Smoking cessation is the cornerstone of treatment for chronic bronchitis, as continued smoking can worsen inflammation in the airways and accelerate the progression of the disease. In addition to smoking cessation, other treatments may include bronchodilators (such as albuterol) to help open the airways and improve breathing, postural chest drainage techniques to help clear mucus from the lungs, and antibiotics to treat bacterial infections.
While these treatments can help manage symptoms and prevent complications, they are not as effective as smoking cessation in halting the progression of chronic bronchitis. Therefore, it is important for individuals with chronic bronchitis to quit smoking as soon as possible to slow the disease process and improve their overall health.
Correct Answer is C
Explanation
Hyperventilation refers to an increased rate and depth of breathing, which results in excessive elimination of carbon dioxide (CO2) from the body. Carbon dioxide is an acidic gas that helps regulate the pH of the blood. When too much CO2 is lost through hyperventilation, it causes a decrease in the partial pressure of carbon dioxide in the blood (PaCO2), leading to a condition called hypocapnia.
Hypocapnia can cause symptoms such as lightheadedness, dizziness, and tingling in the fingers and toes.
