Which of the following changes is NOT typically associated with chronic bronchitis?

Question

BlackTom AI · Accepted Answer

When evaluating which change is NOT typically associated with chronic bronchitis, I’ll examine each option in the context of the disease’s pathophysiology.
Option 1: Chronic inflammation leading to airway obstruction and gas trapping. Chronic bronchitis is characterized by ongoing airway inflammation that contributes to obstruction and can cause gas trapping, especially during exhalation. This option describes a core feature and is consistent with the condition.
Option 2: Mucous overproduction and impaired mucociliary clearance. A hallmark of chronic bronchitis is goblet cell hyperplasia and submucosal gland enlargement causing excessive mucus production, along with impaired clearance due to damaged or overwhelmed cilia. This option correctly reflects a key aspect of the disease.
Option 3: Hypertrophy and hyperplasia of goblet cells. Goblet cell proliferation is a classic histopathologic change in chronic bronchitis, leading to more mucus production. This option aligns with established pathology.
Option 4: Increased number of ciliated epithelial cells. In chronic bronchitis, the focus is often on mucus overproduction and mucus clearance impairment, with ciliary function typically reduced or damaged rather than increased in number. An increase in ciliature is not a typical feature; ciliated cells may be damaged or show impaired motility, not expansion in their numbers. This option describes a change that does not match the usual inflammatory and mucous-overproduction pattern of chronic bronchitis, making it the outlier among the statements.
In summary, options 1–3 describe well-known aspects of chronic bronchitis pathology, while option 4 describes a change that is not typically associated with the condition, highlighting a discrepancy with the disease’s usual ciliary and mucus-protective dynamics.
