that's peripheral, meaning "on the outside edge," in this case, at the far reaches of the blood supply. i think this is another indication of a ritualistic practice (see the thread on fake charting). what they mean to communicate is that the patient's peripheral circulation is ok, because it looks to them as if the fingers and toes (or whatever they are mentioning) are warm and pink. of course, if there is no sensation or motion (as for a complete spinal cord lesion above the level of the part being checked) the "sensation/motion" parts aren't really there, now, are they?
"making a mistake" habitually or just because everyone else does it doesn't make it safe or ok; "charting differently from you" is acceptable if it is accurate. your facility probably has a list of acceptable abbreviations with their definitions. review it, and if necessary, post it for review or have the charge nurse mention this in staff meeting.
this is lazy (and inaccurate) charting. feel free, yea, feel obligated to chart accurately. "toes warm, pink/purple/grey/whatever, blanch to pressure (means they get white when you squeeze them), capillary refill less than 3 seconds (or however long it takes for the white part to pink up again)." you don't do this at the nail bed, so it doesn't matter about the polish when you check the fingers-- look at the fingertips. if it hurts for her to have her toes touched, then that should be noted too. why is that?
