Final answer:
The correct answer is 'All of the above'. EMR, CPOE, and medical imaging are all part of online management of the entire order tracking and documentation process.
Step-by-step explanation:
All of the above is the correct answer. Online management of the entire order tracking and documentation process from order entry to return of results can be achieved through different systems. EMR (Electronic Medical Records) is a digital version of a patient's paper chart, CPOE (Computerized Physician Order Entry) is the process of electronically entering medical orders, and medical imaging refers to the use of various technologies (such as X-rays, MRIs, or CT scans) to produce detailed images of the body. All three options play a role in the management of the order tracking and documentation process.
