Answer:
Consider reframing her thoughts on the exam, using the cognitive model.
Explanation:
According to the cognitive model proposed by Aaron Beck, our feelings are consecuence of our thoughts and interpretations of the real world.
Thoughts ------> Emotion -------> Behavior.
In this Particular case, Lorena was feeling very anxious, but the feeling of anxiousness is a consequence of the thoughts that Lorena has about the exam.
Lorena is probably thinking that she is going to fail the exam, no matter how much she prepares, she will fail. That thought is causing Lorena to feel anxious, even if she prepares.
Lorena has to modify her anticipatory thoughts in order for the anxiety to fade away.
