A patient is receiving an intermittent tube feeding/bolus of 300cc formula, four times per day. The formula provides 1.5 kcal/cc and 795cc water/liter. The patient’s estimated daily fluid requirement is 1800cc/24 hours. How much additional water will be required per feeding?

1)	212cc per feeding ?

2)	101cc per feeding

3)	239cc per feeding

4)	199cc per feeding

A TPN prescription consists of the following:
500ml 50% dextrose
500ml 8.5% amino acids
500ml 10% lipids
This will provide how many total calories and how many grams of protein?

1)	1520 total kcal and 42.5g protein

2)	1570 total kcal and 21.3g protein

3)	2020 total kcal and 42.5g protein

4)	1570 total kcal and 42.5g protein?

Answer 1

1. Answer T:a 212 ml

The amount of feed given to patient= 300 X 4= 1200 ml of formula feed.

The amount of water in 1 litre feed = 795 ml

The amount of water recieved through feeds the entire day = 795 X 1.2 = 954ml /24 hours

Patient's requirement = 1800 ml

Deficit = 1800- 954 = 846 ml

If it is given complementary to feed, then it will be given 4 times daily. Hence additional water to be given along with feed = 846/4 =212ml

2 amount of calories in:

1gm carbohydrates = 4 kcal

1gm protein = 4 kcal

1gm fat = 9kcal

Amount of carbohydrate given to patient = 50% of 500ml = 250 gm

Amount of proteins = 8.5% of 500ml = 44 gms

Amount of fat = 10% of 500ml = 50 gms

Total calories = 250 x4 + 44x 4 + 50x 9 = 1620 kcal

Approximate to nearest answer

1570 kcal and 42.5gms of protein
