The purpose of the Bishop's score is to:

Choice A reason:

Drying the newborn's skin thoroughly is the nurse's priority after assuring a patent airway because it reduces evaporative heat loss by the newborn and prevents cold stress. Cold stress can lead to hypoxia, hypoglycemia, acidosis, and increased bilirubin levels. Drying the newborn also stimulates breathing and crying, which are signs of a healthy newborn.

Choice B reason:

Administering phytonadione IM is not the nurse's priority because it is not an immediate life-saving intervention. Phytonadione is given to prevent hemorrhagic disease of the newborn, which is caused by vitamin K deficiency. However, this condition usually occurs after the first day of life, so administering phytonadione can be delayed until after the initial assessment and stabilization of the newborn.

Choice C reason:

Documenting the Apgar score is not the nurse's priority because it is not an action that directly affects the newborn's well-being. The Apgar score is a tool to assess the newborn's condition at 1 and 5 minutes after birth based on five criteria: heart rate, respiratory effort, muscle tone, reflex irritability, and color. The Apgar score can help guide the nurse's interventions, but it is not more important than providing care to the newborn.

Choice D reason:

Applying identification bands is not the nurse's priority because it is not an urgent or essential action. Identification bands are used to ensure the safety and security of the newborn and prevent errors or mix-ups. However, applying identification bands can be done after the newborn is dried, warmed, and assessed for any problems.

Choice A reason:

Hypertonia is not a characteristic of a preterm infant, but rather of a post-term infant. Hypertonia means increased muscle tone or stiffness, which is more common in infants who are overdue. Preterm infants have poor muscle tone and less subcutaneous fat.

Choice B reason:

Long toenails are also not a characteristic of a preterm infant but of a post-term infant. Long toenails indicate that the infant has grown beyond the expected gestational age. Preterm infants have short and brittle nails.

Choice C reason:

Lanugo is a characteristic of a preterm infant. Lanugo is fine, downy hair that covers the body of the fetus. It usually disappears by the 36th week of gestation, but preterm infants may still have it at birth.

Choice D reason:

Dry skin is not a characteristic of a preterm infant but of a post-term infant. Dry skin indicates that the infant has lost moisture and subcutaneous fat due to prolonged exposure to the amniotic fluid. Preterm infants have thin and transparent skin that may be covered by vernix caseosa, a white, cheesy substance that protects the skin from the amniotic fluid.
