護理師指導家長關於幼兒汽車安全座椅的使用，何者正確？
A nurse is teaching a parent about child car seat safety. Which instruction is correct?
- AUse a rear-facing seat until at least age 2✓ 正解至少使用後向式座椅至2歲
- BPlace the car seat in the front passenger seat將汽車座椅放置在乘客座前方
- CSwitch to a booster seat as soon as the child can sit一旦兒童能坐立即換用增高墊
- DThe harness should be loose to allow for movement束帶應鬆弛以允許活動
兒童乘車安全座椅的使用具有嚴格的安全規範。根據美國小兒科學會（AAP）建議，幼兒應儘可能使用後向式（Rear-facing）安全座椅，至少到 2 歲或達到座椅製造商規定的最高身高體重限制。後向式座椅能為幼兒脆弱的頸部與脊椎提供更好的保護，在發生撞擊時可大幅降低傷害風險。其他選項如放置於前座、束帶過鬆或過早改用增高墊，皆違反兒童安全原則。
Strict safety standards govern the use of pediatric car seats. According to the American Academy of Pediatrics (AAP), infants and toddlers should remain in a rear-facing seat for as long as possible, at least until age 2 or until they reach the maximum height and weight allowed by the seat manufacturer. Rear-facing seats provide superior protection for the fragile neck and spine of young children and substantially reduce the risk of injury in a collision. Other options, such as placing the seat in the front passenger seat, loose harness straps, or switching to a booster seat too early, all violate child safety principles.
