Question

A 2-day-old infant who weighs 6 lb (2722 g) is fed formula every 4 hours. Newborns require about 73 mL of fluid per pound (454 g) of body weight each day. In light of this information, approximately how much formula should the infant receive at each feeding?
a. 1 1 to 2 oz (30 to 60 mL)
b. 2 2 to 3 oz (60 to 90 mL)
c. 3 3 to 4 oz (90 to 120 mL)
d. 4 4 to 5 oz (120 to 150 mL)

Answer 1

Answer:

b. 2 2 to 3 oz (60 to 90 mL)

Explanation:

The answer would be 72.94 ml/times

In this problem, the infant is fed for every 4 hours.

Then, the frequency of feeding for a day would be: (24hours/day) / 4 (hours/times)= 6 times/ day.

The volume of feeding for a day that the infant need would be: $2722\times\frac{454}{73}$ = 473.68ml/day

The number of milk for every fed would be: (473.68ml/day)/ (6 times/day)=  72.94 ml/times

Hence option b seems most appropriate answer
