Which of the following type of croup is most common
Bacterial
Viral
Fungal
Autoimmune
Autoimmune
The Correct Answer is B
Croup is a common respiratory illness in young children, characterized by inflammation of the upper airways (including the larynx and trachea) that leads to a characteristic barking cough and difficulty breathing. Croup is most commonly caused by viral infections, particularly parainfluenza virus, although other viruses such as respiratory syncytial virus (RSV) and influenza virus can also be responsible. 
Bacterial croup is rare and usually occurs in children who have an underlying condition that makes them more susceptible to bacterial infections, such as immunodeficiency or a history of recurrent respiratory infections. Fungal croup is also rare and usually occurs in children with a weakened immune system or a history of exposure to contaminated soil or other environmental sources of fungi.
Autoimmune croup is not a recognized medical condition. While some autoimmune disorders can affect the respiratory system (such as systemic lupus erythematosus), they do not typically cause croup-like symptoms.

Correct Answer is C
Explanation
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 B
Explanation
The correct answer is B. Systolic pressure less than 120 mmHg and diastolic pressure less than 80 mmHg is considered normal blood pressure in adults according to current guidelines. A systolic pressure between 140-150 mmHg (option A) would be classified as stage 1 hypertension, while a systolic pressure greater than 140 mmHg and diastolic pressure of 100 mmHg (option D) would be classified as stage 2 hypertension. A systolic pressure less than 100 mmHg regardless of diastolic pressure (option C) would be considered low blood pressure.
