Evidently they are using 1 oz= 30 ml and 1 qt.= 1000 ml
9 oz= 270
1/2 qt= 500
6 oz= 180
12 oz= 360
TOTAL= 1310

know what conversion factors they are using.....here are some site with common ones
Medical Calculations and Conversions
Health Care: Common Conversion Factors
Weight
1 kilogram (kg) = 2.2 pounds (lb) = 1000 g
1 lb = 454 g = .454 kg = 16 oz
kg x 2.2-5 = kg
lb x 0.454 = kg
1 oz = 28.349 g
1 g = 1000 mg
oz = 28.349 = g
g x 0.935 = oz
Liquids
1 oz = 30 milliliters (ml)
1 tbsp = 3 teaspoons (tsp) = 15 ml
1 tsp = 5 ml
2 tbsp = 1 fl oz
4 tbsp = 1/4 c = 2 oz
1 ml = 1 cc
1 cup © = 8 fl. oz = 16 tablespoons (tbsp) = 1/2 pt
2 c = 16 fl oz = 1 pt = 1/2 qt
4 qt = 1 gal
1 L = 1000 ml
Length
1 m = 3.281 ft = 39.37 in.
in. x 25.4 = mm
in. x 2.54 = cm
mm x 0.0394 = in.
cm x 0.394 = in.
ft x 0.305 = m
m x 3.281 = ft
m x 1.094 = yd
yd x 0.914 = m
Volume
US fl gal x 0.833 = UK gal
US fl oz x 1.041 = UK fl oz
US fl oz x 29.572 = ml
l (litre) x 1.056 = US fl qt
US fl qt x 0.947 = l (litre)

Esme, apparently her/his book is using 500 ml per pint.....

I'm with Don1984 - I don't like it when they use 1 qt = 1,000 mL, but that's the equivalent that makes the 2nd problem work.
Oh...my bad....forget what I gave you. No wonder this poor student is confused.

I dont need any pity. Just looking for a bit of help and clarification
Em! Esme was taking responsibility for her perceived error. Have you sorted the issue of your book out now? I would like to know the name of the book, that way if we run into this issue here at AN again we can "solve" it much more quickly!
Uhm....no honey, I wasn't giving pity.....I gave different information confusing the situation even more. morte pointed it out to me. My goal is only to help. I never judge (well seldom judge) and I am always fair(always).
I agree with Morte what is the name of the book so we can know how to help, and not further confuse, in the future.

It's every bit as absurd to say that 1 pint = 500 mL as it would be to say that pi = 3
So now 1 gallon = 4 liters?
precisely , which is why I want to know the name of the book! It should be trashed! ASAP!

Intake and output is not math, it's arithmetic. No matter what the liquid is, you add the number of cc that went in (Intake, I) and the number of cc that came out (Output, O). That's pretty much it.
If they want to know what the balance is, that means that you lok at the difference between intake and output.
If there was more intake than output, the patient is in positive fluid balance (positive here is not necessarily a good thing-- it means a positive number, greater than zero). Do the subtraction.
If output was greater than intake, that's a negative fluid balance (negative is sometimes a very good thing indeed, if someone was fluid-overloaded in the first place and you want him to pee out more than he takes in). Do the subtraction.
Does this make it clearer for you?
