Maybe it only takes effect when the worm is inside her. I think there is possibility she can change her appearance all the time. I remember watching the episode when Stockman said he turned her human again, I was thinking how. Then after the scene with worm she was mutant again with ability to switch between human and serpent form, like having a human body with snake arms. I notice she is normal for a few moments when she was on the phone talking with Leo when footbots brought poisoned and unconscious Raph, Mikey and Casey. In The Pig and The Rhino she said she was losing her mind and that's why she couldn't switch back, maybe Stockman  made something to stabilize Karai's mind and now she can switch to her human form.

This is not the first time that there are some uncertainties and flaws in episodes. We'll just have to wait and see what happens when  the worm gets out of her.
