Final answer:
Surgery is the process that does not usually occur at most clinics, as they typically focus on outpatient services and do not have the specialized facilities required for surgical procedures.
Step-by-step explanation:
The process that does NOT occur at most clinics is c. Surgery. Most clinics are equipped to handle billing, manage laboratories for tests (labs), and dispense medications (prescriptions). However, surgeries are usually conducted in specialized facilities or hospitals that have the necessary infrastructure and staff to support such complex medical procedures.
Clinics often focus on outpatient services and may not have the extensive array of resources that surgeries require.
