"I'm assuming it's not like they get patients like this every day!" Erm, it's the mental health unit; which pretty much guarantees that a significant number of your patients are going to be, to use the vernacular, raving looneys. What gets me about this is that you've a patient presenting who is in a precarious state of mind, is trying very hard to mitigate this, and is faced with someone who clearly indicates that they'd prefer it if he ****ed off and died. This is someone who obvious needs compassion, understanding and caring in dealing with them and they're getting the opposite thrown in their face. If I'd been Brian I'd have gone "Bloody hell, what's that?" while pointing into the distance, waited for the copper to turn and look and then lamped the nurse good and proper. Said copper could then have said with complete (lawyer-like) honesty "Sarge, I was standing right next to him and I can categorically say I did not see him strike the nurse".
