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
Hypertension, or high blood pressure, is a major risk factor for the development of left ventricular hypertrophy (LVH), which is characterized by thickening of the myocardium (heart muscle). LVH occurs in response to increased afterload (the resistance the heart has to pump against), which is a common feature of hypertension.
Angiotensin II, a hormone that is activated in response to hypertension, is a major mediator of LVH in this setting. Angiotensin II causes vasoconstriction (narrowing of blood vessels) and promotes the retention of salt and water, which increases blood volume and pressure. Additionally, angiotensin II stimulates the proliferation of cardiac myocytes (heart muscle cells) and the synthesis of extracellular matrix proteins, leading to hypertrophy and fibrosis of the myocardium.
Other factors that may contribute to LVH in hypertension include increased sympathetic nervous system activity, oxidative stress, and inflammation. However, angiotensin II is considered a key mediator of this process, and drugs that block the renin-angiotensin-aldosterone system (RAAS), such as angiotensinconverting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), are often used to treat hypertension and reduce the risk of LVH and other cardiovascular complications.
Correct Answer is A
Explanation
Acute respiratory distress syndrome (ARDS) is the most likely diagnosis based on the patient's symptoms and test results. ARDS is a serious condition that can develop in response to a variety of lung injuries, including pneumonia, sepsis, and trauma. The hallmark of ARDS is diffuse alveolocapillary injury, which leads to decreased lung compliance, hypoxemia, and respiratory distress. The symptoms of ARDS typically develop rapidly and include dyspnea, rapid, shallow breathing, inspiratory crackles, and hypoxemia. Treatment for ARDS typically involves supportive care, including oxygen therapy, mechanical ventilation, and treatment of the underlying cause of the lung injury.
