Final answer:

The signs of early vitamin K deficiency in newborns include temperature instability, apnea, bradycardia, hypotension, difficulty feeding, irritability, and limpness. Symptoms of late-onset disease may include seizures, bulging fontanel, stiff neck, hemiparesis, and opisthotonos.

Step-by-step explanation:

The signs of early vitamin K deficiency in newborns include temperature instability, apnea (cessation of breathing), bradycardia (slow heart rate), hypotension, difficulty feeding, irritability, and limpness. When asleep, the baby may be difficult to wake up. Symptoms of late-onset disease are more likely to include seizures, bulging fontanel (soft spot), stiff neck, hemiparesis (weakness on one side of the body), and opisthotonos (rigid body with arched back and head thrown backward).
