Assessment findings of a 3-hour-old newborn include: axillary temperature of 97.7┬░F, heart rate of 140 beats/minute with a soft murmur, and irregular respiratory rate at 42 breaths/min. Based on these findings, what action should the nurse implement?

The correct action for the nurse to take in this scenario is to record the findings on the flow sheet. The newborn's axillary temperature, heart rate, and respiratory rate are within normal limits for a 3-hour-old newborn. Therefore, there is no immediate need for intervention or further assessment. Swaddling the infant in a warm blanket, placing a pulse oximeter on the heel, or checking the vital signs in 15 minutes are not necessary actions based on the normal assessment findings presented. These actions could potentially disrupt the newborn or lead to unnecessary interventions when the baby is stable.
