Final answer:
The RN should take the apical heart rate and respirations of a 4-hour-old baby.
Step-by-step explanation:
A certified nursing assistant (CNA) is working with a registered nurse (RN) in the neonatal nursery. Which of the following actions should the RN perform rather than delegating it to the CNA?
Out of the mentioned actions, taking the apical heart rate and respirations of a 4-hour-old baby should be performed by the RN rather than delegated to the CNA. This is because heart rate and respirations are critical indicators of a newborn's well-being and may require immediate medical attention if abnormal. The RN is trained to accurately assess and interpret these vital signs to ensure the baby's safety.
