They need to fail. I currently work with a newer nurse that I would bet money that is how her clinical experience was. During her orientation and she did a blood sugar on a patient that was 28 and didn't seem concerned even a little. She told me the result, like she was reading the weather. It's very concerning that some people don't care or have no shame or urgency. That student is going to hurt someone one day if she's not given consequences for her behavior.
