1Mar 21, '13 by ChristineNQuote from EmilyEmilyBe 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 negativeany recommendations on a site that offers practice problems on intake and output???Esme12 likes this.

1Mar 21, '13 by EmilyEmily1. 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.

3Mar 21, '13 by CT Pixie, ASN, LPN, RNQuote from EmilyEmilyOk, 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 fluid1. 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

I only have few minutes, so I didn't get timet to figure out the 2nd one. 
0Mar 21, '13 by CT Pixie, ASN, LPN, RNI 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. 
0Mar 21, '13 by mortenow 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.Quote from EmilyEmilymy book says 1 pint equals 500 mL. I'm still getting the wrong answer

0Mar 21, '13 by morteoops, 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!Quote from EmilyEmily. my book says 1 pint equals 500 mL. I'm still getting the wrong answer

There's simply no logic to them.Esme12 likes this. 
3Mar 21, '13 by Guy in Babyland, BSN, RNEvidently 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
