We do not use bags for simulation. It would not be feasible the way we run our scenarios because students draw numbers and are then assigned a scenario. They do not know what is going to happen to their 'patients" or what equipment they will need before the simulation session.
We do have an IV start kit for the skills lab bag. However, we have these separated from the rest of the bag and the students must sign for this equipment the day of use as it is distributed. The kits contain catheters, syringes, sterile saline, etc.
I actually don't know what legal authority gives nursing schools permission to distribute syringes and needles (normally needing a perscription in California unless the city is allowing pharmacy sale without a perscription under the state's Disease Prevention Demonstration Project). You might want to ask your dean about the legal guidelines for access, distribution, and disposal of syringes that the school is accountable to or submit the question to you state's BRN.
