Question 8

What is the primary consequence of airway hyperresponsiveness in asthma?

Accepted Answer

Increased sensitivity to environmental triggers

Answer

Reduced inflammation

Answer

Improved lung function

Answer

Decreased airway resistance

Question 9

Which structural change in the airways is commonly associated with chronic asthma?

Accepted Answer

Smooth muscle hypertrophy

Answer

Reduction in mucus glands

Answer

Decreased epithelial thickness

Answer

Increased airway diameter

Question 10

What role does bronchial hyperreactivity play in asthma?

Accepted Answer

It leads to exaggerated bronchoconstriction in response to stimuli

Answer

It enhances airflow

Answer

It decreases mucus secretion

Answer

It prevents airway narrowing

Question 11

What is the primary physiological change in the lungs during an asthma attack?

Accepted Answer

Increased airway resistance

Answer

Decreased respiratory rate

Answer

Decreased lung volume

Answer

Increased lung compliance

Question 12

How does bronchial remodeling contribute to the progression of asthma?

Accepted Answer

It leads to permanent changes in airway structure

Answer

It reverses airway inflammation

Answer

It increases airflow acuity

Answer

It decreases mucus production
