Do you own your own stethescope? Can you continue to breathe regularly thru the entire shift? Can you hold your bladder for 8-12 hours? Can you survive on caffeine and chocolate?
If you answered yes to all of the above questions, hold a valid RN licence in the country of your choice, then yes, you can be employed.
I certainly hope so anyway, cause I am 10 years older than you and work as many shifts as I want to!
