"I guess I failed as a nurse." BAMMMM!!!!!!!!!!! She is self aware about it. Guess the author was scolded by the fans.
The mangaka is actually... surprisingly proficient in English. Even if all he (well, I assume he's a he) does is machine/Google translate, he can still construct sentences correctly and know what's right and wrong. I posted in a few chapters back where I noticed his Twitter was linked in the description and he was even replying to people in English.
Hell, he could be legit bilingual. Or even someone posting here. I've seen several times where discussion on chapters was almost seemingly purposefully addressed later that I would be surprised if he wasn't reading comments.
But, even if he isn't, I love this manga. It's great and he's really taking a novel and interesting approach to isekai (and even doing so with reverse isekai at that). He's definitely talented because he realizes his story is not merely limited to tropes like others have done. Like, even with supposedly much more realistic reverse isekai like GATE and the like... they never touched the concept of foreign diseases and magic realistically from OUR point of view. And considering he brought up containment and quarantine procedures and even had them investing how magic worked before having to just give up and admit that they currently don't understand how it could work (since it violates known physics, unless she's acting on something we can't normally detect like neutrinos (which actually ARE detectable, just very difficult to do so right now) or dark energy/matter (which are... not... aside us from doing math and realizing that galaxies shouldn't exist as they do currently without something else since they actually lack enough gravity/force/matter/whatever as it stands, which means something of our understanding of science is incomplete and/or wrong) or something). Bonus points for including stuff like breaking out thermal imagining when she conjures fire. How many other mangaka would have thought of doing that? Whereas, in our world, that would probably be one of the first things scientists would want to use (since it doesn't harm or hinder the patient and can show you how it's formed).

Or Become a breeding mother so that Magic would become an everyday thing on earth
That comes later in the hentai doujin.

What are the chances she can teach random Japanese people how to do magic?
Teach random Japanese people how she was taught to do magic? Easy.
For them to actually do magic by learning it without her, I dunno, sharing mana/magic or whatever? ...Who knows? Maybe no one on Earth can use it. Or maybe her kids could, even if they are "half Terran." Or perhaps anyone can use it if taught and trained in it. My guess? Either she's the only one that can use magic on Earth or the government tells her "Don't teach this magic stuff to anyone, kudasai." and they just use it for physics and science research without any interest in the actually learning magic bit.
