Which of the following risk factors is associated with a client having a higher risk of experiencing status asthmaticus?

A. Previous stroke: A prior cerebrovascular accident does not by itself predispose a client to status asthmaticus. B. Bronchial pneumonia: Acute lower respiratory infection can worsen asthma but is not the classic historical risk factor that signals a markedly higher risk for status asthmaticus. C. Irritants and hypersensitivity to medications: Exposure to irritants or drug hypersensitivity can precipitate severe exacerbations, increasing risk, but this reflects triggers rather than prior disease severity. D. Previous intubation due to status asthmaticus episode: A history of prior intubation for status asthmaticus indicates past severe, life-threatening exacerbation and is strongly associated with a higher risk of future status asthmaticus.
