how do i calculate intake and output?

I would quess that intake would be calculating the amount of fluid intake( adding together all fluid by each size cup), output,typically, adding together the cc's each time you empty a foley. Just a quess though.

One time on my test they made it tricky by having some things in mL and some in cups so you had to get everything into the same unit so be ready.

i'm only in level 1 and i have an exam coming up for my basic concepts/fundamentals of nursing class. my professor gave us a blueprint on how many questions on each topic will be on the exam. she mentioned that there will be 2 questions on intake and output where we will need a pen or pencil. i'm assuming we will be calculating but i'm not sure what she was talking about. we didn't have a lecture on it, but does anyone know what she may be possibly talking about on calculating intake/output?? or questions on that topic? she usually asks us nclex style questions

What course are you in? Fundie's typically coveres I&O extensively...along w/other "basic" care."

I&O is all in and out - reglardless of cath or not. You use a 'hat' or a 'catch' when they output. All fluids...i.e. IV & PO are ordered & calculated in most cases mL's...you may have to calculate cc's to mL's as follows:

1 cc = 1 cubic centimeter

1 ml = 1 milliliter

The prefix milli means 1/1000th.

One liter is defined as the volume of a 10 cm cube.

10 x 10 x 10 = 1000 cc.

If 1 ml is 1/1000 of a liter, and one liter is 1000 cc, then:

1 /1000 x 1000 = 1.

1 cc = 1 ml.

Sooooo easy - 'most' facilities have computer systems that calculate - you just verify/administer/DOCUMENT if they are an I&O!

1 cup = 8 oz

1 oz = 30ml

1L = 1000ml

Ex patient had 1 cup coffee for am

8oz broth for lunch

And 500ml pitcher.

How many mls total did the patient have? Patient is on a 700 ml fluid restriction. Did the patient go over?

I just made this up but I'm pretty sure thats how you're going to be tested.

Also don't forget iv fluids tha infuse into the patient as well

Total up how many cc's or mL's of intake (including IV's, IV flushes, any blood products that the patient received, tube feeds) and also total up how many cc's or mL's of output (urine, liquid stool, emesis, any estimated blood loss from surgery if applicable, NG output). It helps to know basic conversions and measurements.

30mL = 1oz

120mL = 4oz

240mL = 8oz

5mL = 1tsp

15mL = 1tbsp (the last two are more applicable to peds)

Also if the patient is drinking coffee, do not forget to include creamers if the patient used any! that also counts as intake. Creamers are 15mL each.
