I don't think 5 VDC can harm the nervous system such that it doesn't recover.

It isn't the voltage that kills, it is the current. The threshold for death is 0.2 amps. That would be achieved at five volts if her resistance was 25 ohms.

I think she got the 120V in the other side of the charger.

Where?

From one finger to another finger or on the surface of the skin. Where would .2 amps driven by a potential of 5 VDC kill? Read up on how the human body reacts to DC currents.
