Tread lightly. I respect your need to speak up about the injustice you are seeing. Consider who you confide in, however. You don't know if the person you report her to is her best friend, married to her 3rd cousin, or dating her brother if you know what I mean. Nursing networking is no different than any other network...sometimes bad behavior is overlooked by who you know. I'm glad you recognize her behavior as despicable. Is she taking care of her patients, whether she thinks they are good or bad? I don't mean is she nice, etc, I mean is she meeting their care needs, pain relief, hygiene, etc? If she is treating them within standard, I might be tempted to lay low and let her dig her own grave. If her behavior is as blatant as you say, no doubt someone has already taken notice of it or will soon. The preferable thing would be for a peer or superior of hers to recognize the behavior and report it. Sometimes nursing students can be viewed as being overly zealous in their perception of "abuses" and you risk not being taken seriously. However, If she is denying the "bad" patients appropriate and timely care, you have an obligation to seek out a trusted nursing instructor in your school. Good luck on your decision and please be reassured that, while we all have prejudices and biases, I would say the vast majority of peers do not act in this manner.
