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
At high altitudes, the air pressure is decreased, and there is less oxygen available in each breath. This leads to a decreased partial pressure of oxygen in the lungs, which can cause hypoxemia (low oxygen levels in the blood). Hyperventilation may initially help to increase oxygen delivery to the body, but it can also lead to respiratory alkalosis and decrease oxygen delivery to the tissues in the long run.
Correct Answer is D
Explanation
Hemoptysis is the coughing up of blood or bloody secretions from the respiratory tract. It is a sign of a serious condition and should be reported immediately to a healthcare provider. In this case, the patient's cold and cough may have led to irritation and inflammation of the respiratory tract, resulting in hemoptysis.
