Which asthma classification is defined by symptoms present throughout the day, nighttime awakenings up to seven times per week, high inhaler use, and an FEV1 less than 60% of predicted?

Which asthma classification is defined by symptoms present throughout the day, nighttime awakenings up to seven times per week, high inhaler use, and an FEV1 less than 60% of predicted?

• A. Mild intermittent
• B. Mild persistent
• C. Moderate persistent
• D. Severe persistent

Answer: (D)

This item tests how asthma severity is classified by symptom frequency, nighttime awakenings, rescue inhaler use, and lung function. When symptoms occur throughout the day, nighttime awakenings are frequent (up to seven times per week), there is high reliance on a rescue inhaler, and FEV1 is less than 60% of predicted, this pattern fits the most severe category. The marked daytime symptoms and poor lung function indicate persistent, high-risk disease that typically requires intensive controller therapy and may involve systemic treatment. In milder forms, symptoms and nightly awakenings are less frequent and FEV1 is better (not this low), so they don’t match this level of severity.
