Answer is OPTION A- Status asthmaticus refers to the typical chronic nature of asthma

status asthmaticus is a acute severe asthma or a severe asthma exacerbation

it refers to an asthma attack that doesn't improve with traditional treatments, such as inhaled bronchodilators

An upper respiratory infection is one of the most common causes of a status asthmaticus attack. The infection increases the amount of mucus in a person's lungs, making it harder for them to breathe. Other potential causes include: allergic reactions to foods

Asthma is a major noncommunicable disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. Symptoms may occur several times in a day or week in affected individuals, and for some people become worse during physical activity or at night. During an asthma attack, the lining of the bronchial tubes swell, causing the airways to narrow and reducing the flow of air into and out of the lungs. Recurrent asthma symptoms frequently cause sleeplessness, daytime fatigue, reduced activity levels and school and work absenteeism. Asthma has a relatively low fatality rate compared to other chronic diseases.

Facts about asthma

  • WHO estimates that 235 million people currently suffer from asthma. Asthma is the most common noncommunicable disease among children

The causes

The fundamental causes of asthma are not completely understood. The strongest risk factors for developing asthma are a combination of genetic predisposition with environmental exposure to inhaled substances and particles that may provoke allergic reactions or irritate the airways, such as:

  • indoor allergens (for example, house dust mites in bedding, carpets and stuffed furniture, pollution and pet dander)
  • outdoor allergens (such as pollens and moulds)
  • tobacco smoke
  • chemical irritants in the workplace
  • air pollution.
