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

A newborn with a temperature of 37.0°C (98.6°F) is within the normal range for newborns and does not require immediate intervention.

Choice B rationale

A newborn who has not voided within 27 hours post-delivery requires immediate intervention. Newborns should void within the first 24 hours of life. Failure to void may indicate dehydration, urinary tract obstruction, or renal issues.

Choice C rationale

A newborn who has not passed meconium within 18 hours post-delivery is concerning but not as urgent as not voiding. Newborns typically pass meconium within the first 24-48 hours.

Choice D rationale

Acrocyanosis, or bluish discoloration of the hands and feet, is common in newborns and usually resolves on its own. It does not require immediate intervention.
