Final answer:
A newborn should not be fed if their respiratory rate is 60 breaths per minute or higher, as it may indicate distress and the potential for safe feeding to be compromised, requiring medical attention to stabilize the baby.
Step-by-step explanation:
The respiratory rate that indicates a newborn should not be fed is d) 60 breaths per minute. Newborns with normal respiratory rates between 30 and 60 breaths per minute can typically be fed safely. However, a respiratory rate of 60 breaths per minute or higher may indicate distress and an increased work of breathing, which can interfere with safe feeding.
It is essential to monitor this closely since increased respiratory rates can lead to exhaustion and further compromise the baby's instability. In such cases, medical attention is required to stabilize the newborn's condition before proceeding with feeding.
