Correct answer: B — Compare readings with her personal best and follow her written asthma action plan
Peak expiratory flow is most useful when compared with the patient's personal best and interpreted using an asthma action plan. A fall from personal best may indicate worsening control and need for escalation. The patient should seek urgent help if readings or symptoms meet red-zone criteria.
