Final answer:
Cydney's asthma symptoms and their frequency, coupled with her use of a rescue inhaler and FEV1 levels, suggest that she has 'Moderate Persistent Asthma.'
Step-by-step explanation:
Based on the information provided about Cydney's asthma condition, we can classify her asthma severity using the guidelines for severity assessment. Cydney is experiencing daily but not continual symptoms, symptoms at nighttime, and she is using her rescue inhaler. Additionally, her Forced Expiratory Volume in 1 second (FEV1) is between 60-80% predicted. These factors correlate with the classification of 'Moderate Persistent Asthma.' Moderate persistent asthma is characterized by daily symptoms, use of rescue inhaler more than twice a week, but not more than once in a single day, and FEV1 between 60-80% of the predicted value.
