Dialysis Nurse Certification

Hi everyone,

I'm hoping to travel with a travel nurse agency asap as an LPN
but I'm wondering if I must be certified as dialysis nurse before
even being considered. I've applied with Foundation medical staffing
and I'm wondering if they would require this of me before receiving any
travel assignments.

Does anyone have any idea what the cost of certification is
Is a mandatory to be certified
how long does the certification process take
Any one who can give me some idea of what to expect with Foundation staffing
of any other travel agency would be very helpful...Thanks
