You come in to your patient and hear a cooing sound coming from the baby. The family says ‘’Oh listen to the cute noise the baby is making" You assess some more and realize that the coos are consistent with the babies respirations. You:

A) Caput succedaneum present:
Caput succedaneum refers to the swelling of the soft tissues on the newborn's head, typically caused by the pressure exerted during vaginal delivery. This condition is often seen after a prolonged labor or in cases of vacuum-assisted delivery. It presents as a soft, fluid-filled swelling that crosses the suture lines, which distinguishes it from a cephalhematoma (a collection of blood). This swelling is usually benign and resolves within a few days after birth without intervention.

B) Severe molding present:
Molding refers to the shaping of the newborn's skull bones as they overlap to pass through the birth canal during delivery. It typically presents as elongated or asymmetric head shapes, particularly in the vertex presentation. Severe molding would not involve swelling of the soft tissues and would not cross the suture lines. This term is typically used to describe changes in the shape of the skull bones rather than soft tissue swelling.

C) Cephalhematoma present:
A cephalhematoma is a collection of blood between the newborn's skull and the periosteum (the membrane covering the bones). Unlike caput succedaneum, a cephalhematoma does not cross the suture lines because the blood is confined to the area overlying the affected bone. Cephalhematomas are typically the result of trauma during delivery, such as forceps or vacuum extraction. The swelling in a cephalhematoma is firmer and does not appear as soft or fluid-filled as caput succedaneum.

D) Fontanels soft and flat:
The fontanels are the soft spots on the baby’s head where the skull bones have not yet fused. The anterior fontanel is usually the most prominent, and the posterior fontanel is much smaller. While fontanels should be soft and flat in the early stages, this option doesn't describe the swelling or soft tissue findings as described in the question. The soft, fluid-filled swelling over the head would be more indicative of caput succedaneum rather than a normal fontanel finding.

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.
