If she is a nurse and she truely made all these mistakes, I feel worried about ptients in the hospoital where she works.

Sorry but this is how I feel.
And yes I am very upset for the boy

The only justification I can see for her is that maybe she has panicked. When you leave a flat tire and wheel ( and a water bottle too) and then take a turn into an unmarked trail ... there must be something wrong like she has started freaking out.
