How are you able to stay abreast of medical terminology?
The interviewer is looking broadly at how talented and capable you are to perform all the tasks and responsibilities associated with a medical secretary job and how eager you are to keep learning new things. They're also looking at the strength of that talent foundation and the potential to build on it in the future. That's why they're asking how you keep up with medical terminology. It gives them a look at how confident you are in what you do and how much you rely on your abilities to make good things happen. You should cite examples and point to specific accomplishments in your response but how you answer is as important as what you answer, especially with this particular line of questioning. Showing positive body language and having an upbeat, energetic tone of voice can go a long way.
