Final answer:
A nurse should report abnormal clinical manifestations like excessive crying, irritability, sensitivity to light, lethargy, and vomiting, which could suggest serious underlying health issues in a 3-year-old toddler.
Step-by-step explanation:
A nurse assessing a 3-year-old toddler at a well-child visit should report certain abnormal clinical manifestations to the provider that may indicate underlying health issues. These manifestations might include excessive crying, irritability, heightened sensitivity to light, unusual lethargy, and vomiting, similar to what was described in the provided clinical cases. Additional concerns to watch out for in a toddler would be symptoms like temperature instability, apnea (cessation of breathing), bradycardia (slow heart rate), hypotension, difficulty feeding, irritability, and limpness. More serious signs that require immediate attention 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). Early and accurate reporting of these symptoms is crucial for prompt diagnosis and treatment.
