Hi there,
I encourage you to look into dialysis, I know many LPNs who find this a more rewarding job than other positions. It also pays well (although not quite as much as long term care in my area).
I think it's an excellent plan for you to get a position and training as a PCT while you're in nursing school. For one thing, the work of a nurse in an outpatient clinic overlaps that of the PCT (setting up/"tearing down" the machine, dialyzing patients - the nurse just has
additional duties). Getting training now as a PCT will give you an advantage when you start working as a dialysis nurse, especially if it's with the same company.
I would, for convenience, try to get a local PCT position. If no LPN position opens up, you can always transfer to a more distant clinic once you have graduated. This should be no problem.
As for pay, don't quote me on this, but in my area LPNs make about $6-7/hour more than PCTs. As I mentioned, only nursing homes pay more (about $1-2/hr - IMO, they are desperate to get nurses and always have plenty of openings). Hospitals usually pay less than either dialysis clinics or LTC.
Good luck to you, keep us posted!
