Asthma is characterised by attacks of breathlessness and wheezing, with exacerbations associated with variable airflow obstruction. True or false.
True
False
Correct!
That’s right. Attacks of breathlessness and wheezing are characteristics of asthma, and exacerbations are associated with variable airflow obstruction.
Incorrect
Not quite. Attacks of breathlessness and wheezing are characteristics of asthma and exacerbations are associated with variable airflow obstruction meaning the statement is true.

Which of these changes are associated with the airway of a patient with asthma?
Loss of epithelium surface and cartilage integrity
Increased smooth muscle mass
Inflammation
All of them
Correct!
That’s right. All of these are changes from a normal to asthmatic airway. These changes can lead to inflammation, airway obstruction, hyper-responsiveness, airway oedema, and mucus hypersecretion.
Incorrect!
Almost. All of these are changes from a normal to asthmatic airway.
