“I have to be sure that this person is ready and safe to practise and I wasn’t prepared to put my professional reputation and registration on the line at that point.”
no she's probably not going to outright say "this person isn't safe around children" she has to be diplomatic but it's strongly implied she wouldn't make a good nurse.
