A nurse is preparing to administer 1 mg Phytonadione to a neonate.

The medication is available in 1 mg/0.5 mL. How much should the nurse administer?

(Round to the nearest tenth. Use a leading zero when applicable. Do not use a trailing zero.)

Choice A rationale

Faint red marks on the plantar surface are more common in preterm infants and are not typically seen in post-term infants.

Choice B rationale

Copious vernix is usually seen in preterm infants. Post-term infants often have little to no vernix.

Choice C rationale

Dry, cracked skin is a common finding in post-term infants due to prolonged exposure to the amniotic fluid.

Choice D rationale

Scant scalp hair is more common in preterm infants. Post-term infants usually have more developed hair.

Choice A rationale

Stretching arms out and then back in is a common reflex in newborns known as the Moro reflex. It is not a sign of feeding readiness but rather a response to a sudden loss of support or a loud noise.

Choice B rationale

Turning the head toward a parent’s voice is a sign of auditory recognition and bonding, not necessarily feeding readiness. It indicates the infant’s ability to recognize familiar sounds.

Choice C rationale

Grasping a parent’s finger when placed in the infant’s palm is a primitive reflex known as the palmar grasp reflex. It is not related to feeding readiness but is a normal reflexive action in newborns.

Choice D rationale

Bringing their hand to their mouth is a sign of feeding readiness. This action indicates that the infant is hungry and ready to feed. It is an early cue that the baby is ready to eat.
