Final answer:
The nurse should monitor the toddler for the clinical manifestation of anemia associated with lead toxicity.
Step-by-step explanation:
Toddlers who are exposed to lead toxicity may experience severe effects on their hematopoietic system, including a possible reduction in red blood cell formation and consequent anemia. It is essential to track the toddler's hemoglobin levels in order to determine the extent of their anemia. Anemia from lead exposure manifests as weakness, weariness, pallor, and decreased appetite. Regular monitoring allows for early discovery, which in turn allows for timely action and suitable management. It is essential to treat the underlying source of the toddler's lead exposure in order to avoid more issues and protect their general health.
