Which newborn is at the lowest risk for elevated unconjugated bilirubin levels?

The newborn with significant bruising from a face presentation.

The premature newborn.

The baby born at 41 weeks' gestation.

The newborn with O+ blood type, born to a mother with O- blood type.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

(Incorrect) The newborn with significant bruising from a face presentation is at an increased risk of elevated unconjugated bilirubin levels. Bruising can lead to the breakdown of red blood cells, increasing bilirubin production.

Choice B rationale:

(Incorrect) The premature newborn is at a higher risk of elevated unconjugated bilirubin levels. Premature infants often have an underdeveloped liver, which can lead to reduced bilirubin processing and clearance.

Choice C rationale:

(Correct) The baby born at 41 weeks' gestation is at the lowest risk for elevated unconjugated bilirubin levels. By this stage, the baby's liver is more mature, allowing for efficient processing and clearance of bilirubin.

Choice D rationale:

(Incorrect) The newborn with O+ blood type, born to a mother with O- blood type, is at an increased risk of elevated unconjugated bilirubin levels if the baby's blood type is Rh-positive and the mother's is Rh-negative. This situation can lead to Rh incompatibility and hemolytic disease of the newborn, causing higher bilirubin levels.

Correct Answer is B

Explanation

A. This condition typically results from excessive loss of acid, often due to vomiting or diuretics. It is not the most likely concern in a cold environment with an infant who has been crying and kicking.

B. A cold environment can lead to nonshivering thermogenesis in newborns, where they metabolize brown fat to generate heat. This process can lead to increased lactic acid production, potentially causing metabolic acidosis. The infant's fatigue following crying and kicking may indicate that the body has expended significant energy to stay warm, making metabolic acidosis a priority concern.

C. While hunger could be a reason for crying, it is not the priority concern in this scenario where environmental cold and fatigue are present.

D. Overstimulation might cause crying, but the environmental cold and subsequent risk of metabolic acidosis are more critical concerns in this context.

A. "This is a Mongolian spot, which is found on many newborns.". B. "This is a caput succedaneum, which is a collection of fluid from pressure of the vacuum extractor.". C. "This is erythema toxicum, which is a transient allergic reaction that causes edema in the skin.". D. "This is a cephalhematoma, which will resolve on its own in 3 to 5 days.".

Correct Answer is B

Explanation

"This is a caput succedaneum, which is a collection of fluid from the pressure of the vacuum extractor.”.

Choice A rationale:

A Mongolian spot is a benign, flat, bluish-gray pigmented area often found on the sacral or gluteal area of some newborns with darker skin tones. It is not related to the swelling on the newborn's head caused by vacuum extraction.

Choice B rationale:

A caput succedaneum is a localized swelling on the baby's scalp that occurs due to pressure from the vacuum extractor during delivery. It is typically soft and may cross the suture lines. This explanation accurately describes the swelling the baby has on his head.

Choice C rationale:

Erythema toxicum is a common rash that appears as small red bumps with white or yellow centers. It is a benign and self-resolving condition that does not cause swelling on the head or involve the suture lines.

Choice D rationale:

A cephalhematoma is a collection of blood between the skull and the periosteum that does not cross the suture lines. It is caused by trauma during birth and may take weeks to months to resolve. This does not match the description of the swelling caused by vacuum extraction.
