A 3-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?
2 to 3 oz (60 to 90 mL)
1 to 1.5 oz (30 to 45 mL)
4 to 5 oz (120 to 150 mL)
3 to 4 oz (90 to 120 mL)
The Correct Answer is A
A) 2 to 3 oz (60 to 90 mL):
To determine the appropriate amount of formula for this infant, first calculate the total fluid requirements for the day. The infant weighs 6 lb (2722 g), and newborns typically need 73 mL of fluid per pound of body weight per day.
6 lb × 73 mL = 438 mL of fluid required daily.
Since the infant is fed every 4 hours, this equates to approximately 6 feedings in a 24-hour period.
438 mL ÷ 6 feedings = 73 mL per feeding.
Converting this to ounces (since 1 oz = 30 mL), the infant would need about 2.5 oz per feeding. Therefore, 2 to 3 oz (60 to 90 mL) per feeding is appropriate to meet the infant's daily fluid needs.
B) 1 to 1.5 oz (30 to 45 mL):
This amount is insufficient for the infant’s daily fluid needs. At 1 to 1.5 oz per feeding, the total intake for the day would be only 180 to 270 mL, which is well below the required 438 mL. This could lead to dehydration and inadequate nourishment.
C) 4 to 5 oz (120 to 150 mL):
This amount is excessive for a 3-day-old infant. Newborns typically consume much smaller amounts at each feeding due to their smaller stomach capacity. Overfeeding could lead to discomfort and potential digestive issues.
D) 3 to 4 oz (90 to 120 mL):
While this range is closer to the required amount, it is still slightly too much for a 3-day-old infant. At this age, the recommended amount is closer to 2.5 oz per feeding, so 3 to 4 oz may be excessive and could contribute to overfeeding, which might be uncomfortable for the infant.

Correct Answer is ["4"]
Explanation
The Apgar score is calculated based on five criteria, each scored from 0 to 2:
-
Heart rate
- 0 = Absent
- 1 = Below 100 beats per minute ✅
- 2 = 100 or more beats per minute
-
Respiratory effort
- 0 = Absent
- 1 = Slow, irregular ✅
- 2 = Good, crying
-
Muscle tone
- 0 = Limp
- 1 = Some flexion of extremities ✅
- 2 = Active motion
-
Reflex irritability (response to stimulation, e.g., suctioning)
- 0 = No response
- 1 = Grimace ✅
- 2 = Crying, active withdrawal
-
Color
- 0 = Blue, pale
- 1 = Body pink, extremities blue
- 2 = Completely pink
Apgar Score Calculation:
- Heart rate: 1
- Respiratory effort: 1
- Muscle tone: 1
- Reflex irritability: 1
- Color: 0
Total Apgar Score: 4
A score of 4 suggests the newborn is in distress and requires immediate medical intervention, such as oxygen support and further assessment.
Correct Answer is A
Explanation
A) Put baby to breast for non-nutritive sucking to calm baby:
Non-nutritive sucking (sucking without feeding) is a natural way for babies to self-soothe. It can help calm a fussy infant and also promote bonding between mother and baby. This action also stimulates milk production in the mother. It's a safe and effective way to comfort the baby without introducing unnecessary interventions. Non-nutritive sucking can help regulate the baby's sucking reflexes and provide comfort until the next feeding.
B) Give the baby pacifier:
While pacifiers can help some babies self-soothe, they can interfere with breastfeeding, especially in the early days. Introducing a pacifier too soon may confuse the baby’s natural sucking pattern and affect the latch, which can impact breastfeeding success. It’s typically recommended to wait until breastfeeding is well-established, around 3-4 weeks, before introducing a pacifier.
C) Put the baby in the nursery so mom can get some rest:
While maternal rest is important, removing the baby from the mother's care in the early postpartum period may interfere with the breastfeeding process. Breastfeeding on demand is crucial for establishing a good milk supply, and keeping the baby close for frequent feedings (and comfort) will help with this. Encouraging rest is important, but it shouldn't come at the expense of bonding and feeding.
D) Supplement with formula:
There is no indication that the baby is not getting enough nutrition at this point. Fussy behavior between feedings is common in newborns and can be due to various factors such as the baby's need for comfort, a growth spurt, or a short interval between feedings. Supplementing with formula is not necessary unless there is a clear indication of inadequate milk supply or other medical concerns, which isn’t evident in this situation.
