Guilty as charged. To other nurses, and sometimes docs, I will maybe say "the GI bleed in bed 6" to the groggy resident who has no freaking idea who Mr John Doe is at 2am, or "Can you check vitals on bed six for me? When I am tied up with a doc doing a procedure. I never intend for it to be dehumanizing, just a fast way to ID what I need and who I need it on, ot to jog someone else memory.
When I am with my pt's, I never say "Mr. Bed six, can I get you some pain medication to make it easier for you to cough and get some rest?" I know who they are, address them by the name we agreed on, and they have my TLC and all of my knowledge and skills at their disposal. Yes I may ask someone to"See what Bed six wants" while I can't get there, at least I am making sure someone addresses bed sixes bell.
I think even if I was a pt, knowing how I did that, and never intending to dehumanize anyone, it would not bother me in the least. Sorry, just being honest here.
