I dont think you understood what I wrote.
Door knob assesment is sort of the general assesment (or initial assesment).
We are also required to take a full set of vitals from each patient (vitals are vital..).
However when you enter the patients room, you should be able to know within the first seconds if this is a sick patient or not. Before you interview or take vitals.
It’s not. Text book thing. Store iit in your mind for after you graduate.
