24 hour calls are rally exhausting, but the hour or two between finishing the shift and falling asleep are very rewarding, you reflect on what you have managed to accomplish. The day team would have came and you take a few minutes to either low key brag about your saves or complain about some encounters. 

The last call was interesting. We were asked to remove three temporary dialysis catheters, a rather mundane procedure that the ICU nurses are very comfortable doing but for whatever reason the medical providers that shift on the floor patients were not. It is very frustrating, using the excuse of "not comfortable".. No one is born comfortable doing anything. I offered each MD to accompany me while we remove the catheter from their patient and only 1/3 took the offer. That is two providers who are not comfortable providing an aspect of care for their patients and who don't want to learn how to provide that care.. That was frustrating.
