Final answer:
The incident described is an example of medication non-compliance, where the patient did not use their prescribed medication leading to severe respiratory distress.
Step-by-step explanation:
The incident described in the question is an example of medication non-compliance or patient non-adherence. Mrs. N. was not using her inhaler, despite Evelyn's reports that there was enough medication left in it. This lack of adherence to the prescribed treatment led to Mrs. N.'s severe respiratory distress and subsequent hospitalization.
Medication non-compliance can have serious consequences and is a common issue in healthcare. It is important for patients to follow their prescribed treatment plans and communicate any difficulties or concerns they may have with their healthcare providers.
