A patient presents with wheezes and hives after allergen exposure; which condition is most likely?

Explanation:
Wheezes together with hives after allergen exposure points to an acute systemic allergic reaction. In anaphylaxis, mast cells release histamine and other mediators that cause rapid airway constriction (bronchospasm) leading to wheezing, while also producing skin manifestations like hives. The combination of airway symptoms with urticaria after exposure is a hallmark of anaphylaxis rather than a purely airway-focused disease. Asthma can present with wheeze, but it typically lacks the immediate hives and systemic skin involvement seen with anaphylaxis. COPD and bronchitis involve chronic or infectious airway processes and are not characteristically precipitated by allergen exposure with sudden hives.
