Agreed. That is what I mean. Despite you telling everyone four hours, they still try to push it. Stick to your guns Mel. Been there done that. Don't let them give you the line that if his b/p pulse ok it's ok to increase the rate. It's about all the other side effects that a lot of these nurses cannot get through their craniums.They are to follow a doctors order, not make up their own. Four hours at least, okay, good luck. Smooth sailing to you guys.
