What is true regarding FAS and NAS?

Choice A reason:

Holding the newborn vertically, allowing one foot to touch the crib surface, will elicit the stepping reflex, not the Moro reflex. The stepping reflex is when the newborn makes stepping movements when held upright with one foot touching a flat surface.

Choice B reason:

Turning the newborn's head quickly to one side will elicit the tonic neck reflex, not the Moro reflex. The tonic neck reflex is when the newborn assumes a "fencing”. position, with the arm and leg extended on the side to which the head is turned and the opposite arm and leg flexed.

Choice C reason:

Performing a sharp hand clap near the infant will elicit the Moro reflex, also known as the startle reflex. The Moro reflex is when the newborn responds to a sudden loss of support or a loud noise by extending and abducting the arms, spreading the fingers, and then bringing the arms together and crying.

Choice D reason:

Placing a finger at the base of the newborn's toes will elicit the Babinski reflex, not the Moro reflex. The Babinski reflex is when the newborn fans out the toes and dorsiflexes the big toe when the sole of the foot is stroked.

Choice A reason:

Nevus flammeus is a port-wine stain, a type of birthmark that is present at birth and does not fade over time. It is caused by a malformation of capillaries in the skin and appears as a reddish-purple patch. It can occur anywhere on the body but is not associated with swelling or suture lines.

Choice B reason:

Cephalhematoma is a collection of blood under the periosteum of the skull bone, usually caused by trauma during delivery. It appears as a swollen area on the head that does not cross the suture line because it is limited by the boundaries of the bone. It usually resolves within a few weeks or months without treatment.

Choice C reason:

Molding is the temporary change in the shape of the newborn's head due to the pressure of the birth canal during delivery. It results in an elongated or cone-shaped head that may cross the suture line. It usually resolves within a few days as the skull bones return to their normal position.

Choice D reason:

Caput succedaneum is a localized swelling of the scalp, usually caused by pressure from the cervix or vacuum extraction during delivery. It appears as a soft, puffy area on the head that crosses the suture line because it is not limited by the bone. It usually resolves within a few days without treatment.
