I hope that if you will be responsible for telemetry patients, you will have protocols in place not only to recognize dysrhyrthmias but what to do about them. I have been certified in ACLS for 20 years and I would recommend that your hospital train all RNs who are responsible for tele patients to be trained to at least that level.
I would also insist that the hospital equip your crash carts with AED's (most units are doing this, since airliners now have them) and train everyone on the unit to apply them.
Adminstrators need to understand that monitoring means more than just hooking up a patient to a machine. I once saw an OB physician order an ER nurse to take a patient OFF of a fetal monitor. When the doctor explained that the monitor may show fetal distress, and there was no one to interpret it, we were simply creating a legal record of negligence. We did train nurses in fetal monitoring and established a telemetry monitoring system to L&D.
Excuse an ignorant ER nurse's naivete, but to me the words "step-down" and "telemety" are almost interchangable.
