A nurse is collecting data from a newborn who is 4 hours old.
Which of the following findings should the nurse report to the provider?

Choice A rationale

. Applying oxygen is a supportive measure for the client experiencing significant blood loss and circulatory compromise, but it is not the highest priority action to stop the hemorrhage. The physiological basis for applying oxygen is to maximize the oxygen content of the circulating blood, addressing tissue hypoxia secondary to hypovolemic shock.

Choice B rationale

. Weighing the perineal pad is a necessary step to accurately quantify blood loss (1 gram of weight equals approximately 1 milliliter of blood) for accurate diagnosis of postpartum hemorrhage (PPH) and to guide treatment. However, it is an assessment and documentation action, not the most critical intervention to immediately address the source of the bleeding.

Choice C rationale

. Performing a fundal massage is the highest priority and most critical intervention when a client reports rapid and heavy postpartum bleeding, which suggests uterine atony (a soft, boggy uterus). Uterine atony is the most common cause of early postpartum hemorrhage, and manual stimulation immediately causes the uterine muscle fibers to contract, which constricts the blood vessels and rapidly reduces blood loss.

Choice D rationale

. Monitoring urine output is an important assessment of renal perfusion and fluid status, which is essential to track the progression of potential hypovolemic shock due to hemorrhage. A urine output of less than 30 mL/hour suggests inadequate renal perfusion. However, this is an assessment and a later indicator of the severity of shock, not the immediate, life-saving intervention needed to halt the bleeding source.

Choice A rationale

A late preterm newborn (born between 34 0/7 and 36 6/7 weeks of gestation) often exhibits periods of alertness, but they are also commonly noted to have a sleepy, less sustained alert state compared to a full-term neonate. Their neurological immaturity contributes to poor state regulation and a less vigorous overall response.

Choice B rationale

Thermal instability is an expected finding in late preterm newborns because they have less subcutaneous fat (insulation) than term infants, a higher surface area-to-volume ratio, and immature hypothalamic temperature regulation. This increased vulnerability necessitates careful monitoring and environmental thermoregulation (normal axillary temperature: 36.5°C to 37.3°C).

Choice C rationale

Late preterm newborns are at an increased risk of hypoglycemia (serum glucose ≤ 40 mg/dL) due to inadequate glycogen stores, increased metabolic demands, and immature gluconeogenesis pathways. Hyperglycemia (serum glucose ≥ 125 mg/dL) is not typically expected unless the infant is under high stress or receiving high glucose infusions.

Choice D rationale

Leathery or cracked, dry skin is characteristic of a post-term newborn (born after 42 weeks) due to prolonged exposure to amniotic fluid and desiccation. Late preterm newborns have relatively thin, smooth skin with visible blood vessels because the subcutaneous fat layer is not yet fully developed.
