Be more specific what sort of help do you need? If you are trying to find the fluid balance it is just subtracting the larger number from smaller and if the intake is greater than 0 the pt is positive, if output is greater than 0 the pt is negative

1. Client had the following at lunch and use the following equivalents for problems: 1 cup=8oz, 1 glass=4 oz
4oz fruit cocktail, 1 tunafish sandwich, 1/2 cup of tea, 1/4 pt of milk. Total in mL

4oz X 30= 120ml
1/2 X8oz=4 X 30ml=120ml
1/4pt X 500= 125ml

120+120+125=365 mL

the book says the answer is 245 mL. I dont know how they came to this

2. Calculate the following individual items and give the total number of milliliters: 3 popsicles (3 oz each), 1/2 qt iced tea, 1 1/2 glasses water, 12 oz soft drink. Total in mL

9oz X 30=270mL
1/2 qt X 946= 473 mL
1 1/2 glasses of water= 1.5 X 4=6oz X 30= 180 mL
12 oz soft drink= 12 x 30mL= 360 mL

Total = 1283 mL

the book says its 1310 mL.

what am I doing wrong?

Ok, well you have 3 sets of mL's (120, 120 and 125). The patient only had tea and milk for a total of 245mL, the fruit cocktail isn't a fluid

I only have few minutes, so I didn't get timet to figure out the 2nd one.

I think the problem lies with the 1/2 quart. There are 32 ounces in a quart, so 1/2 quart would be 16 ounces.
Then you'd have

270mL for popsicle (3*3=9 9x30=270)
480mL for iced tea (16 x 30= 480)
180mL for water (6 x 30=180)
360 for soda (12 x 30= 360)
total of 1290
which is 20mL less than what the answer says..can't figure this one out...grrr! Its probably staring me right in the face and I'm just not seeing it.

Em..check your equivalence (sp) chart....what is an ounce equal in ml? what is a pint equal, etc.

my book says 1 pint equals 500 mL. I'm still getting the wrong answer

now take that and extrapolate that ratio to the rest of the volumes, and you will be closer. I am thinking the book is using the literal ratio of oz to mil, which is sl more than 1 to 30.....in which case you will needs to find that reference.

oops, I take back my last post....1 oz is less than 30 ml...29. something....a quart is actually 946, which makes a pint 473. Which really plays havoc with your problems, I dearly wish you luck!
