The bottom line of recovery nurse in an endoscopy clinic is (to be blunt) get the patient out the door ASAP.
The patient is screened by the GI doctor and the anesthesiologist prior to the procedure and deemed healthy. In recovery they may get 1 - 2 set of vitals, maybe some juice and crackers, (some clinics don't even give refreshments), and are wheeled out the door to their ride home.
You may rarely use a stethoscope, may never listen to lung or heart sounds, not even listen for borborygmus, (that is the first time I used that word, had to look up the spelling
!) The emphasis will be speed, get the paperwork done.
I would stop by the clinic prior to your trial shift, maybe they will let you just "observe" how the staff/nurses function. Or ask for a blank recovery nurses form/paperwork so you will be familiar with it. Realize the form may have many areas that do not need to be filled in, areas that are routinely left blank or the nurse writes NA.
This is what I have observed in my GI recovery nursing. I don't want you to look like a "bad nurse." Maybe this particular clinic is different, the nurses do a head to toe assessment of each patient in recovery, listen to lung sounds, etc.? But I would be really surprised if that happens.
