Final answer:
Due to Deanna's error in appointment scheduling by overbooking slots, patient wait times may increase, leading to frustration and a negative impact on the office's public relations.
Step-by-step explanation:
Deanna's misunderstanding of the appointment matrix and her actions of making two appointments in each slot rather than one will likely lead to overbooking and longer wait times for patients. This could result in patients feeling frustrated, potentially compromising the quality of care due to decreased time spent with each patient, and putting additional pressure on the healthcare providers and staff. As a result, such a mistake could adversely impact public relations in the office. Patients may perceive the office as disorganized or disrespectful of their time, which could lead to negative reviews and a damaged reputation.
