The irony is not lost on me when I get asked to:

1) Review a patient who hadn't peed in 12 hours, when I myself hadn't peed in just as long.

2) Review a patient with suboptimal oral intake, when I myself hadn't had food or fluids in just as long. (And they end up with IV fluids and I end up with no fluids at all, still.)

3) Assess a confused patient and I ask them the current time and date to check degree of disorientation... only to realise I have no idea what the correct answer is, either, myself. Because I hadn't slept in 28 hours.
