the following two experiences are what interns (not med students) did, but....
when i was a senior resident one of my friends from another service at another hospital had an intern who pushed 1000U regular insulin on a patient. she (my friend) said she gave him d50 then literally poured sugar down his throat for 6 hours and then kept him on a d10 drip.
another friend (also different service at different hospital) told me about one of the interns when she was a senior who was told to give 5000U sq heparin for dvt prophylaxis on a pre-op transplant donor and instead gave 50000U iv.
Ball ist rund. Spiel dauert neunzig minuten. Soviel ist schon mal klar. Alles andere ist theorie.
