U-100 Insulin Dosage Calculation (Two Examples)



Sharing buttons:

in this order we are asked to administer

Humalog you 178 units sub-cut daily at

7:30 a.m. we need to determine how much

we need to administer and what syringe

we would use the first thing to notice

is we are talking about Humalog which is

insulin and is not just any particular

type of interest insulin it is you 100

which specifically tells us that this

Humalog has 100 units per one ml so

every milliliter of this drug contains

100 units now because insulin is often

administered at home by the part by the

person who needs it there needed to be a

nice and easy way for individuals to

administer and calculate and administer

the drug themselves so there are what we

call you 100 syringes and these you 100

syringes are labeled with units so so

far in this module we have seen syringes

that measured milliliters but what we're

going to be seeing when we're talking

about insulin are syringes that are

specifically calibrated for you 100 and

instead of filling them up to a

milliliter count we're filling them up

to a unit count so what makes that great

is when you see you 100 you know all we

need to do is to figure out one how many

units you need to administer so how many

units you need to administer and once

you figure out how many units you need

to determine then what syringe you use

and once you have that you are done and

because we're dealing with the paper and

pencil test and we're not necessarily

actually filling syringes we're also

going to want to label and shade those

syringes so let's just answer these two

short questions we know we're dealing

with

you 100 which is important how many

units of you 100 do we need to

administer according to this we need to

administer 78 units and now we need to

choose the syringe we know immediately

that a three milliliter syringe is not

appropriate because we're not measuring

milliliters or measuring units so now we

have 100 units or 50 units well 78 units

do not fit in a 50 unit syringe so I'm

going to measure and mark 78 units on my

100 unit syringe we can see that it goes

up by twos 70 and then 2 4 6 8 so I will

draw a line right here at 78

I will specifically write 78 units to

let whoever is reading this know that

this is what I've marked 78 units and it

will shade up to that point the key

thing to remember once again is we are

dealing with you 100 there are no

conversions needed when we are dealing

with you 100 a common mistake is for

students to use the 100 units per

milliliter converted into milliliters

and label a milliliter syringe that

would be inappropriate to do because we

have calibrated you 100 syringes if we

were dealing with you 500 insulin which

we'll see coming up there's a little bit

more we need to do but let's look at the

next example we see no volyn regular you

100 we need to administer 45 units

sub-cut should only be one sub-cut at

7:30 which syringe do we use and how

much should we administer and we're told

what's available to us as you 100 and

it's units 100 minutes per 1 million

if you want to pause the video now and

try this on your own please do i'm going

to look at this and see I'm talking

about insulin it is you 100 insulin and

as soon as I see you 100 I do not need

to do

conversion so no conversions needed

because this is you 100 so the first

question was how many units do I need to

administer I need to administer 45 units

and then the second question is what

syringe immediately I see that this one

ml syringe is not going to be needed I

need a syringe that measures units and

down here I have two calibrated u-100

syringes and I see here that 45 units

that's going to fit on my 50 unit

syringe so I will shade up to 45 and I

will mark 45 units and that's it
