Thank you all for your comments. You bolstered my confidence in confronting her today. (I've never reported anyone and don't want to if I not necessary. My rule has been to confront the person directly the first time; if it happens again, I tell them that if it happens a third time, I'll realize my warnings aren't working and will report them. So far, no one has reached that 3rd time.)
Anyway, after asking for a moment to talk, the PT and I found a private spot and I told her that I had always liked working with her but that I was surprised -- and actually offended -- by the way she kept trying to oversee everything my orientee and I were doing yesterday with that particular patient. She acted quite surprised and said she hadn't meant to offend me. She said the reason she kept questioning us was because the day before she had tried to alert the nurse caring for the patient then, but had felt that that nurse had not taken her seriously and had not extended appropriate care to the patient. I told her that I did not know about the previous day or the nurse on duty then, but that I still didn't think it was appropriate for her keep questioning us and even wanting to give the patient the tylenol. She kept apologizing and saying she realized it hadn't been necessary to doubt my care. I told her that not only was her behavior demeaning to my orientee and me, but that I felt she was encouraging the patient to lose confidence in us particularly when she'd said, "but I care about this patient so much." She said she only said it because she DOES care about the patient and she thought it would make the patient feel better but she understood now how it made my orientee and me look in comparison, and she was very sorry. She said she'd try very hard not to behave this way in the future. I accepted her apology and will hope that she really will think in the future about her behavior affects others. As I said above, if it happens a 2nd time, I'll tell her the next time I'll be reporting her, but I have a feeling it's not going to happen again.
Again, thank you all for your input and support!
