Choice A rationale

Checking the newborn’s capillary blood glucose level is important, especially for a large for gestational age newborn. Large for gestational age newborns are at risk for hypoglycemia (low blood sugar) after birth. Therefore, regular monitoring of the newborn’s blood glucose level is crucial.

Choice B rationale

Placing the newborn under a radiant warmer can help regulate the baby’s body temperature. Newborns, especially those who are large for gestational age, may have difficulty maintaining their body temperature after birth. A radiant warmer can provide the extra warmth the baby needs.

Choice C rationale

Monitoring the newborn’s temperature is important as newborns can lose heat rapidly, they don’t have the ability to control their body temperature as adults do. Temperature regulation in newborns is important to help them stay healthy and comfortable.

Choice D rationale

Monitoring the newborn’s color and frequency of bowel movements is not directly related to the condition described. While it’s an important aspect of newborn care, it’s not a priority in this scenario.

Choice A rationale: A postmature newborn, or one born after 42 weeks of gestation, is likely to exhibit cracked, peeling skin due to the prolonged exposure to amniotic fluid and the absence of vernix. This makes Choice A the correct answer, as it reflects the expected findings for a postmature newborn.

Choice B rationale: Abundant lanugo is typically seen in preterm infants, not postmature infants. Lanugo is a fine, downy hair that covers the fetus and usually disappears by 37 weeks of gestation. Therefore, Choice B is not an expected finding for a postmature newborn.

Choice C rationale: Short, soft fingernails are characteristic of preterm infants. In postmature infants, fingernails are generally long and may extend beyond the fingertips due to prolonged gestation. This makes Choice C an incorrect answer for the expected findings of a postmature newborn.

Choice D rationale: Abundant vernix is typically seen in preterm and term infants. Vernix is a white, cheesy substance that covers the fetal skin to protect it from amniotic fluid. Postmature infants usually have minimal to no vernix present, as it has already been absorbed. Therefore, Choice D is not an expected finding for a postmature newborn.
