Final answer:
Major CNS danger signals in a neonate include poor feeding, lethargy, and abnormal eye movements, in addition to other serious symptoms. Reflexes like the Moro reflex are normal, but abnormal responses or accompanying serious symptoms indicate the need for immediate medical attention.
Step-by-step explanation:
The major CNS danger signals in a neonate that warrant immediate attention include symptoms such as poor feeding, lethargy, abnormal eye movements, temperature instability, apnea, bradycardia, hypotension, irritability, limpness, seizures, bulging fontanel, stiff neck, hemiparesis, and opisthotonos. These symptoms can indicate serious conditions such as early or late-onset neonatal diseases, which may include infections or neurological issues that are often fatal if not treated promptly. While the presence of neonatal reflexes like the Moro reflex is expected and indicates normal neurological development, abnormalities in these reflexes or accompanying symptoms such as those listed should raise concern.
