Carla Iyer came close to accuse her former coworker of killing other patients, addition to conspiring with Michael Shiavo about Terri.
Carla Iyer claimed she was the "Floor Supervisor" while she was an LPN. In many states, an LPN is prevented by law from performing the actions that an RN can, including some of the treatments she gave or performed for Terri.
I hope everyone considers that Carla may not be the best source for information. Her documented statements are a can of worms just waiting to be opened. If she is reliable, great--but if she isn't, it is better to know now.
Most nursing homes are run by LPN's. There is usually an Rn on the house for the whole facility.
She may have been the charge nurse on the floor.
