I welcome you to the profession. So sorry this happened to you as a new nurse. This is why I like to see new nurses in facilities first before striking out in home health or private duty. I feel you need to be mentored by the nurses you interact with daily. Then in a situation such as this, you know your skills aren't a question.
Especially because you're new to nursing, I think your supervisor or DON should give you the reason why this happened. As many have stated, it may be no big deal. I wish you well. Please try to find opportunities to be mentored so that you increase your skill level.
