Answer:
All of the above
Step-by-step explanation:
Health services managers are very important in every healthcare facility. They're responsible for planning, directing and harmonizing/organizing the health services. They're expected to do several things such as: creating work schedules for staff, managing finances such as the patient's billing information, coordinate with the medical staff and the department heads, monitor the funding and budget of the healthcare facility, organize records, etc. So, this explains the answer above (all of the above).
In order to do these things, they have to work together with the healthcare professionals (doctors, nurses, laboratory technicians, etc.)
