Commercial formulas contain 20 calories per ounce. A 1-day-old infant's weight in the morning was 8 lb and he was fed 45 mL at 2 a.m., 5:30 a.m., 8 a.m., 11 a.m., 2 p.m., 4:30 p.m., 8 p.m., and 10:30 p.m. What is the total amount of calories the infant received today?
Correct answer
B
Rationale
The infant was fed 45 mL 8 times, totaling 360 mL. Since 1 oz Ôëê 30 mL, 360 mL ├À 30 mL/oz = 12 oz. At 20 calories per ounce, 12 oz ├ù 20 cal/oz = 240 calories.
