If you feel that this question is difficult to answer, then simply think about the compliments you get from your superiors or co-workers. You sure must have got some compliments from others during work, quote those and speak about it. You can answer by saying ‘I am good at communicating with the patients, I have got many compliments from my co-workers on how well I communicate with the patients. This ability helps me to deal with the stressful situations and thus helps me to be a successful nurse.’
