Final answer:
Preschool-aged children are at a higher risk of falls, drowning, poisoning, and tricycle and bicycle accidents.
Step-by-step explanation:
The injuries that the nurse should identify as occurring in preschool-aged children include falls, drowning, poisoning, tricycle and bicycle accidents. Preschoolers are at a stage of exploration and discovery, which often leads to accidents. They are still developing their coordination skills and may be prone to falls. Drowning is a significant concern as young children can easily access bodies of water and are at a higher risk of drowning. Poisoning can occur if preschoolers accidentally ingest household chemicals or medications. Tricycle and bicycle accidents can occur as they learn to ride and navigate on wheels.
