We just did our yesterday and did a 'Minute-to-Win-It' contest. We used an empty room and there were four stations.1) Do a safety check of the room and find what's missing (ambu, suction, code sheet etc)2) syringe pump was set up for a fentanyl gtt- find all the mistakes (no tubing labeled, wrong weight programmed etc)3) Open the crash cart and pull out all supplies to start an albumin bolus- starting with no IV site4) Open the crash cart and prepare to intubate a 4.0 kg patientAll four ran simultaneously and the first one done 'won' (the winner got to pick their prize first).Prizes were from the dollar store (everyone got a prize) : squirt guns, Disney princess tiaras, bubble stuff.....
