You're about as likely to find a unicorn in the ICU as a type B nurse.
It's good that you're managing your time! BUT...
How critical are these pts? Being a small hospital, are they comparable to a typical stepdown pt? Or are they truly critical -- ventilated, vasoactive drips, medically paralyzed, ARDS-y, on a cooling protocol, on CRRT or ECMO or an IABP? If they are the latter type, if tripled and still have downtime I'd wonder how well you're putting all of the pieces together, vs focusing on *tasks.*
If you are truly on track with the critical thinking, goal oriented stuff, it may help to verbalize your thought processes with your preceptor.
For example, say you have a neurosurg pt on hypertonic saline to keep their Na level 145-155; Na was 135 at 1200 and 143 at 1800. You might say, "I know neurosurg wants it higher, but that is a BIG increase. His urine output has increased a lot and looks dilute. Do you think it could be DI? I think we should notify neurosurg and see if they want to order more labs."
That could eliminate some of the interrogation "how have his Na's been trending? What do you think about that increase? What is his UOP? Could anything else contribute to his UOP, such as a diuretic or pt auto-diuresing? What should you be concerned about with these numbers?"
