161) ANSWER

A) "My peak flow meter can tell me if an asthma episode might be coming, even though I might still be feeling okay."

RATIONALE

Peak expiratory flow readings over time indicate the child s respiratory ability when she is well. Readings of 50 percent below "personal best" indicate an asthma episode is imminent. The meter does not prevent an attack. Critical words are "understands" and "peak expiratory flow meter." Knowledge of this device and how it helps to manage asthma helps to answer the question.
