Final answer:

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.
