Can please someone answer this for me? if that a way of giving meds to someone who has diabetes? I only see it on pt charts who are Diabetics.

It is a predetermined (usually by the MD) scale set for the pt. as a guide on how much insulin to give them for a blood glucose number that is high.


150-200 2U

201-250 4U

and so on

So if Pt. X's BS was 162, this pt. would receive 2 units of insulin according to the sliding scale. There is a scale for each pt. to be followed.

Also, ONLY regular insulin is used with a sliding scale, non of the other ones.

Humalog insulin is also used in the sliding scale. But not as much as Regular insulin.


Specializes in NICU.

In the NICU, we will sometimes see sliding scales for other meds, like potassium (if the level comes back between such and such, give this many; if it comes back lower, give this many, higher give this many, etc.).

Heparin and insulin gtts can be on a sliding scale.
