I am not a doctor, but I do know how to handle firearms, so I would also unload and ensure that the gun is not in a condition to fire. This would probably dock me points for diluting potential evidence or some such horseshit, but it'd still be the right thing to do. Provided you knew what you were doing.
Doing anything to the gun is probably a bad idea, even if you have experience with firearms. This gun came from a gang member, it could be in a very janky altered condition that makes it act unpredictably. If you're going to try to disarm it anyway then you should still move it outside first before attempting that just in case it malfunctions and fires while you're trying to manipulate it
Hospitals have security for a reason. You touching a gun when they have procedures on how to handle this situation is dangerous. If you are on staff you follow procedures. If you are just there and do know about gun safety you would know not to pick up that gun.
A is wrong because whoever wrote this is in no position to evaluate if the person reading it is capable of "to check if the gun is loaded" without blowing their own head off.
D is wrong because the person whoever wrote this is in no position to evaluate if the person reading it is capable of "hold the gun personally" without blowing their own head off.
A is additionally wrong because you don't know the condition of the firearm. If it is not mechanically sound, manipulating it in any way could cause it to discharge in the worst case, or possibly jamming it in an unsafe condition. Best to let someone get it to a safer location before trying anything. There's likely no especially safe direction to allow a firearm to discharge in a hospital, much less the ED.
I agree that's what they want you to answer, but you can't move it to a safe location without handling it, so C necessarily entails D. Unless there's a designated firearm handler in the ER you can call over, which to be fair, maybe there should be.
If you are at a hospital in the hood they probably have armed security. The ones in the city nearest me certainly do. One would hope they know how to safely handle a firearm as well as have some manner of secure storage someplace, so that'd probably be their department. At least until the cops inevitably get involved.
You're being too pedantic about wording. The right answer is to make it most safe while minimizing the chance of it accidentally firing. Simply moving it to a locked room down the hallway is the best way to achieve that.
Unless you pass by a "good person with a gun" seeing you with a gun and killing you because you're carrying a gun on the way.
The only answer is to leave the gun where it is without touching it, exit the room with the patient, lock the door from outside, leave the building yourself, light a cigarette, forget about whatever the problem was, go home, because they aren't paying you enough to get shot on your job
