A nurse is caring for a preterm male newborn admitted to the NICU after vaginal birth at 32 weeks of gestation. Exhibits Select the three findings that require immediate follow-up.

Choice A rationale: A temperature of 36.7° C (98.1° F) is within the normal range for neonates, which typically spans 36.5° C to 37.5° C. Thermoregulation in preterm infants is immature, but this value indicates adequate thermal stability. No signs of hypothermia or hyperthermia are present. Therefore, temperature does not require immediate follow-up unless trends show instability or environmental factors compromise thermal regulation. Choice B rationale: A capillary blood glucose level of 51 mg/dL is within the acceptable range for neonates, which is generally greater than 40 to 45 mg/dL. Although preterm infants are at risk for hypoglycemia due to limited glycogen stores and immature metabolic pathways, this value reflects adequate glucose availability. No signs of jitteriness or lethargy are noted, so immediate follow-up is not required unless glucose levels decline or feeding is inadequate. Choice C rationale: A respiratory rate of 74/min exceeds the normal neonatal range of 30 to 60 breaths per minute. Tachypnea in a preterm infant may indicate respiratory distress syndrome (RDS), especially given the gestational age of 32 weeks and observed signs of labored breathing. Elevated respiratory rate increases energy expenditure and may compromise oxygenation. Immediate follow-up is needed to assess for hypoxemia, initiate respiratory support, and prevent fatigue or apnea. Choice D rationale: A heart rate of 170/min is above the normal neonatal range of 120 to 160 beats per minute. Tachycardia may reflect compensatory response to hypoxia, pain, or increased metabolic demand. In the context of respiratory distress, elevated heart rate suggests systemic stress and possible cardiovascular compromise. Immediate follow-up is necessary to evaluate oxygenation, perfusion, and potential need for intervention such as supplemental oxygen or CPAP.
