She’ll be fine with a regime of good old penicillin, and debriding out the wound and cleaning it. They should give her a tetanus vaccine as part of the therapy.
Also, she’s going to want to decontaminate her home, including pets. Salt and diatomaceous earth should do it. The first will shrivel them and the other will cut their shells so the salt can shrivel them. Don’t inhale the diatomaceous earth - use a high-grade face mask and eye protection. Steam cleaning afterward to get the survivors.

General Reminder to anybody: tetanus only lasts 10 years. If you can’t remember when you last had one, get one.
I looked on Wikipedia (they can’t be too political on tetanus treatment) and it’s not about penicillin for treatment. It’s pretty extensive and I’m hoping not too invasive - sounds like she might be trached.
Diatomaceous earth works great for ants (need a lot of patience but you can kill whole hives of them) and dog type fleas. Good tip.
