Final answer:
HIE is a condition caused by oxygen deprivation to an infant's brain, leading to neurological and physiological symptoms but not typically causing diarrhea.
Step-by-step explanation:
Hypoxic-Ischemic Encephalopathy (HIE) is a condition that occurs when an infant's brain doesn't receive enough oxygen and blood. The signs of HIE include a variety of neurological and physiological symptoms. Common indicators of this condition involve temperature instability, apnea (cessation of breathing), bradycardia (slow heart rate), hypotension (low blood pressure), difficulty feeding, irritability, and limpness. As the condition progresses, further symptoms can emerge such as seizures, bulging fontanel (the soft spot on a baby's head), stiff neck, hemiparesis (weakness on one side of the body), and opisthotonos (a condition where the body spasm causes an arching back and the head to be thrown backward).
One symptom not associated with HIE is diarrhea. This condition is more likely linked with gastrointestinal issues rather than with oxygen deprivation in the brain that characterizes HIE.
