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 A
Explanation
Coronary artery disease (CAD) is a condition where the arteries that supply blood to the heart become narrowed or blocked due to a buildup of plaque. Several risk factors contribute to the development of CAD, including diabetes mellitus, hypertension, obesity, high alcohol consumption, smoking, and a family history of CAD.
Research suggests that individuals with diabetes mellitus are two to four times more likely to develop CAD than those without diabetes. This is because diabetes can lead to damage to the blood vessels and nerves that control the heart, as well as increased inflammation and high levels of blood glucose that can contribute to the buildup of plaque in the arteries.
While hypertension, obesity, and high alcohol consumption are also known risk factors for CAD, they generally do not increase the risk to the same degree as diabetes. Nonetheless, these factors can contribute to the development and progression of CAD and should be addressed through lifestyle modifications and medical interventions.
Correct Answer is B
Explanation
associated with chronic heart failure. Activation of the RAAS system occurs as a compensatory mechanism in response to decreased cardiac output and reduced renal perfusion. The renin-angiotensin-aldosterone system increases blood pressure, maintains blood volume and improves cardiac contractility in the short term, but in the long term it can lead to fluid retention, edema, and worsen cardiac function.
