Final answer:
Signs such as temperature instability, seizures, and limpness are strongly suggestive of non-accidental head trauma to an infant.
Step-by-step explanation:
Strongly suggestive of non-accidental head trauma to an infant includes signs such as temperature instability, apnea (cessation of breathing), bradycardia (slow heart rate), hypotension (low blood pressure), difficulty feeding, irritability, limpness, seizures, bulging fontanel (soft spot), stiff neck, opisthotonos (rigid body with arched back and head thrown backward), and hemiparesis (weakness on one side of the body).
