Thank you, 18G for mentioning getting a report first. Always always always talk to someone before you make patient contact for IFTs.
And be careful with psych patients! I worked at an IFT company for several years and a good portion of our transfers were of the psychiatric variety. I was always pretty relaxed about these guys, and few ever gave me any trouble. (But then again, I'm 6'1'' and 270, built like a Mac truck) But I did have one patient (a twerpy teenager too) who damn near killed my partner and I. I was lucky enough to escape with a few broken ribs, but had I not been quite as quick I would have had a nice stab wound in the chest from the scissors he had concealed on him too. Now, I generally restrain any and all psych patients. Too bad for them, life sucks when you're crazy, and I apologize to no one.
Also, all of those questions you asked, like about having a plan or suicidal ideation? Yeah, the hospital already asked about all that. Not really your place. And why do you need to know? All you need is their diagnosis, their complaints, and whether or not you should just restrain them or really really restrain the crap out of them. Yeah, sure it might be interesting, but unless you have some actual psych training those things have no bearing on how you will deal with this patient. And it's awkward.
