Exhibit 1. The names of the newborn reflexes are? Select all that apply.
rooting.
stepping.
moro.
Babinski.
Correct Answer : A,C,D,F
Choice A rationale:
The newborn reflex called "rooting”. is characterized by turning the head and opening the mouth when the cheek or mouth area is touched. This reflex helps the newborn find the mother's breast for feeding.
Choice B rationale:
"Stepping”. is a newborn reflex where they make stepping movements when held upright with their feet touching a solid surface. This reflex is present at birth but tends to disappear after a few weeks.
Choice C rationale:
The "Moro”. reflex is also known as the startle reflex. It is elicited by a sudden loss of support or loud noise, causing the newborn to throw their arms and legs out and then bring them back in. This reflex usually disappears around 3 to 4 months of age.
Choice D rationale:
The "Babinski”. reflex is characterized by the extension of the big toe and fanning of the other toes when the sole of the foot is stroked. This reflex is present in newborns and should disappear by around 12 months of age.
Choice E rationale:
"Running”. is not a recognized newborn reflex. There is no reflex with this name related to newborns.
Choice F rationale:
The "gag”. reflex is present in newborns and helps protect the airway by causing a gagging response when the back of the throat is stimulated.

Correct Answer is A
Explanation
Choice A rationale:
Placing the newborn in an incubator is essential because the newborn's temperature control mechanism is immature. Premature infants have an underdeveloped thermoregulatory system, making them susceptible to heat loss and cold stress. An incubator provides a controlled, warm environment to maintain the newborn's body temperature within the normal range (around 36.5°C to 37.5°C or 97.7°F to 99.5°F).
Choice B rationale:
Heat increasing the flow of oxygen to the newborn's extremities is not a valid reason for placing the newborn in an incubator. Oxygenation is primarily influenced by respiratory and circulatory mechanisms, not external heat.
Choice C rationale:
The newborn's small body surface area for his weight is not directly related to the need for an incubator. Premature infants have a higher surface area to weight ratio, making them more prone to heat loss, but this is not the primary reason for using an incubator.
Choice D rationale:
Heat facilitating the drainage of mucus is not a reason for placing the newborn in an incubator. Proper positioning and suctioning are used to manage mucus in premature infants, but incubators are primarily for temperature regulation.
Correct Answer is A
Explanation
Choice A rationale:
Cephalhematoma is the correct answer because it presents as a swelling on the newborn's head confined to one cranial bone and does not cross suture lines. It usually resolves on its own within a few weeks to months but can increase the risk of jaundice due to the breakdown of red blood cells in the hematoma.
Choice B rationale:
Nevus flammeus, also known as a port-wine stain, is a type of vascular birthmark. It presents as a flat, pink, or red mark on the skin and does not involve swelling of the head. This choice is unrelated to the findings described in the question and is therefore incorrect.
Choice C rationale:
Caput succedaneum refers to a diffuse, soft tissue swelling of the scalp that does cross suture lines. It is caused by pressure on the head during delivery, leading to edema and bruising. It typically resolves within a few days after birth.
Choice D rationale:
Molding refers to the shaping of the fetal head during childbirth as it passes through the birth canal. It may cause temporary elongation or molding of the head, but it does not present as a localized swollen area. This choice is not applicable to the findings mentioned in the question and is thus incorrect.
