What hormone remains elevated in the immediate postpartum period in a breastfeeding patient?

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.

A) Axillary temp of 96.9F (36.0 C) after 30 minutes of skin-to-skin contact with the mother:
A temperature of 96.9°F (36.0°C) is lower than the expected normal range for a newborn, which is typically between 97.7°F (36.5°C) and 99.5°F (37.5°C). However, after 30 minutes of skin-to-skin contact with the mother, the temperature is likely to increase as the infant benefits from the warmth of the mother's body. If the temperature does not rise or if it continues to decrease, further intervention would be necessary.

B) Respiratory rate of 58 during assessment at beginning of shift:
Newborns may have slightly irregular and rapid breathing patterns, especially right after birth, but this is not a cause for concern unless accompanied by signs of respiratory distress, such as retractions, flaring, or grunting.

C) Heart rate of 162 while crying vigorously after a diaper change:
It is not uncommon for a newborn to have an elevated heart rate when upset or crying. A heart rate of 162 while crying is expected and does not indicate a problem. Once the baby calms down, the heart rate will likely return to its baseline.

D) No void after 8 hours of life:
The absence of a urine output within the first 8 hours of life is concerning and requires immediate follow-up. Newborns typically void within the first 24 hours, and if there is no urine output by 8 hours, it could indicate a potential problem such as dehydration, urinary tract obstruction, or renal dysfunction. A healthcare provider should be notified promptly for further assessment and intervention.
