الإجابة: D. Prior history of intubation and ICU admission
Among the risk factors for asthma exacerbation, the lecture lists prior intubation or ICU admission for asthma. This is the strongest predictor of a severe or fatal attack. Age and wheeze characteristics are not risk factors, and SpO2 91% describes the current attack rather than a risk factor.
