Speaking as a former student nurse, we're taught about MBP, signs and symptoms and syndromes, and to whom to report suspicions (LE, management...).
I will also say that while some ped rooms are monitored via video, I never saw a transmitted picture, a real-time video, or even an observational camera thingy.
Yes, we're in and out all the time. No, we don't let people hurt our patients (and the patient is the one in the bed...).
I would bet a nickel this was not real-time monitored...because if I knew it was going on the first time, I'd've citizen arrested the Mom...and I'd only have known if I saw it happening on a monitor somewhere. And I know that most RNs would not hesitate to do the same...if they knew it was going on.
I also have not watched the vid posted here. I can't bring myself to do so. I had the hardest rotation in pediatrics; I'd rather any other floor than that.
JMHO, as always.
