護理師在教導學步期幼兒家長關於事故預防的知識。下列哪項建議對此年齡層最為重要？
A nurse is teaching a group of parents about injury prevention for toddlers. Which instruction is highest priority for this age group?
- AEnsure the child wears a helmet while riding a tricycle.確保兒童騎三輪車時佩戴安全帽
- BStore all cleaning supplies in high cabinets.將所有清潔用品存放在高處櫃子裡

- DRemove all small toys that can be swallowed.移除所有可能被吞下的小玩具
學步期幼兒（Toddlers）正處於探索環境的階段，其運動能力發展快但判斷力不足，容易發生意外。燒燙傷是此時期常見且致命的傷害，其中熱水器水溫設定過高是居家常見隱憂。將溫度設定在 120°F (48.9°C) 以下，能確保若幼兒誤開水龍頭時，不會在短時間內造成嚴重的全身性燙傷，這是預防致死性傷害的優先衛教項目。
Toddlers are in the stage of exploring their environment, with rapid motor development but immature judgment, making them prone to accidents. Burns are common and potentially fatal injuries during this period, and a hot-water heater set too high is a frequent household hazard. Keeping the temperature setting at or below 120°F (48.9°C) ensures that if a toddler accidentally opens a faucet, it will not produce severe full-thickness burns in a short time; this is a top priority for preventing fatal injuries.
