Question

A 4-month-old infant weighing 11 lb (5 kg) should receive 108 kcal/kg per day. if the formula contains 20 kcal/oz (20 kcal/30 ml), how much formula would the nurse tell the mother to give to her infant each day?

a. 21 oz (630 ml)
b. 27 oz (810 ml)
c. 33 oz (990 ml)
d. 39 oz (1170 ml)

Answer 1

A 4-month-old infant weighing 5 kg requires a total of 540 kcal per day based on the recommended 108 kcal/kg/day. With the formula providing 20 kcal/oz, the mother should be instructed to give the infant 27 oz (810 ml) of formula each day to meet this requirement. so, option b is the correct answer.

Step-by-step explanation:

The question relates to the daily nutritional requirements for a 4-month-old infant and the amount of formula needed to meet those requirements. Based on the information provided, the infant weighs 11 lb (5 kg) and requires 108 kcal/kg per day. With the formula containing 20 kcal/oz (20 kcal/30 ml), we first calculate the total daily calorie requirement for the infant, then convert this requirement into the volume of formula needed.

The total daily calorie requirement for the infant is:

5 kg × 108 kcal/kg/day = 540 kcal/day

To find out how much formula is needed to meet 540 kcal, divide the total number of calories by the number of calories per ounce of formula:

540 kcal/day ÷ 20 kcal/oz = 27 oz/day

Therefore, the nurse would tell the mother to give her infant 27 oz (approximately 810 ml) of formula each day.
