I am a new graduate LPN and just started working at a clinic; I have been assigned to work with the Urologist, but I do not have a lot of experience with this field.
First, when you change a foley catheter, do you need to instill sterile water into the foley 1st before pulling it, so that there will be return since they have the catheter in all the time and there would be very little or no urine in the bladder to determine if you are in the bladder or not? We were not taught this, but I have heard about from around the clinic.
Second, there are two sphincters, right? How do you know you are past both of them if urine will come when you get past the external one? Or will it? Is it possible to inflate the balloon while in between the two sphincters?
Any advice would be of great importance.
