In a 24hr staffed nursing home, do the bedrooms need an emergency light in each bedroom or just escape routes etc

Depends on the results of a fire risk assessment in the bedrooms, if there is adequate borrow light to enable the occupants to find their way out of the room into the corridor safely, then EL may not be required, this also applies to the corridor.

I am an old fart and need to go to the toilet a number of times during the night, but I do not need to put the lights on, the same would apply in an emergency evacuation, so I do not need EL. :)
