Final answer:
The nurse would document the finding as normal when assessing an apical pulse on a baby.
Step-by-step explanation:
The nurse would take the action of documenting the finding as normal when assessing an apical pulse on an 8lb 4oz baby. The apical pulse is the measurement of the heart rate taken by listening with a stethoscope placed at the apex of the heart. The nurse would compare the baby's heart rate to the normal range for newborns, which is around 120-160 beats per minute.
