Final answer:
The child's asthma would be classified as 'Mild persistent' based on the frequency and severity of symptoms, as well as the impact on the child's daily activities.
Step-by-step explanation:
Asthma is a chronic respiratory condition that is characterized by episodes of airway obstruction due to inflammation, bronchospasms, and excessive mucus production. Given the description of the frequency and severity of the symptoms — experiencing asthma symptoms more than twice a week but less than once a day, with an FEV average around 85% of the predicted value and minor limitations in normal activity level — the nurse would classify this child's asthma as Mild persistent.
Asthma severity is typically classified into four categories: intermittent, mild persistent, moderate persistent, and severe persistent. Here, 'mild persistent' is the appropriate classification because the symptoms occur more frequently than in intermittent asthma (which would be less than twice a week) but are not as severe or frequent as moderate or severe persistent asthma.
