It's a double-edged sword. If he googled "lipoma" or similar it would be good, if he googled "painful lump when poked" I would be very wary of him. Double wary if he clicks on a random blog.
By chance, I am a doctor. I spend a lot of time looking things up, even things I'm 80% sure about.
Yes, it's useful to have that knowledge already, and to that I'd say that copying out a textbook is a poor way to learn. It's far better to know the processes behind things or to learn through experience.
This seems like a good thing, not a bad thing.
I'd MUCH prefer to have a doctor verify a diagnosis with reference material than to have them rely on their memory.
