NAECB Signs & Symptoms Of Asthma 5

Question 1

Which occupational exposure is MOST commonly associated with work-related asthma symptoms that improve on weekends?

Accepted Answer

Sensitizers or irritants in the workplace such as isocyanates or flour dust

Answer

Occupational asthma caused by workplace sensitizers like isocyanates (paint sprayers) or flour dust (bakers) classically improves on weekends away from exposure.

Question 2

Which symptom is considered a 'red flag' suggesting potential status asthmaticus?

Accepted Answer

Cyanosis, inability to speak, or altered consciousness during an attack

Answer

Cyanosis, inability to speak, or altered mental status during an asthma attack indicate life-threatening status asthmaticus requiring immediate emergency intervention.

Question 3

Which pattern of eosinophilia would you MOST expect to find in a patient with allergic asthma?

Accepted Answer

Peripheral blood and sputum eosinophilia

Answer

Allergic asthma is characterized by type 2 inflammation with elevated eosinophils in both peripheral blood and induced sputum, reflecting IL-5–driven eosinophil production.

Question 4

A patient reports worsening asthma symptoms after starting a new blood pressure medication. Which drug class is MOST likely responsible?

Accepted Answer

Beta-blockers

Answer

Beta-blockers can precipitate severe bronchoconstriction in asthma patients by blocking beta-2 receptors that normally mediate airway smooth muscle relaxation.

Question 5

Which symptom pattern in children suggests asthma rather than viral bronchiolitis?

Accepted Answer

Recurrent episodes of wheeze triggered by multiple factors including exercise and allergens

Answer

Recurrent wheeze triggered by multiple factors (allergens, exercise, cold air) in children over age 2 suggests asthma rather than isolated viral bronchiolitis.
