Which statement by an 8-year-old female client with asthma indicates that she understands using a peak expiratory flow meter?

A. This statement reflects a proper understanding of the peak flow meter’s purpose — it can help detect early changes in airway function before symptoms are felt, allowing for early intervention and improved asthma control. B. This reflects a misunderstanding of the correct technique — the meter should be reset to zero before each use, and the child should use a full, fast breath to blow into the meter. C. While daily monitoring is helpful, the peak flow meter does not prevent asthma attacks — this statement reflects false reassurance and misunderstanding. D. Peak flow should be measured with a single, forceful breath, not multiple breaths — this indicates incorrect use of the device.
