護理師教導家長兒童安全，關於汽車安全座椅的建議，下列何者正確？
A nurse is teaching a parent about child safety. Which recommendation regarding car seat safety is correct?
- AThe harness should be loose to allow the child to breathe安全帶應鬆弛以讓兒童呼吸
- BKeep the child in a rear-facing seat as long as possible✓ 正解盡可能讓兒童使用向後式安全座椅
- CPlace the car seat in the front passenger seat with the airbag off將汽車安全座椅放置在關閉安全氣囊的前排乘客座
- DFace infants forward as soon as they reach 10 lbs一旦嬰兒達到 10 磅就將其改為向前式坐姿
汽車安全座椅（Car seat）的安全規範以降低碰撞時的衝擊力為核心。根據美國兒科學會（AAP）建議，嬰幼兒應儘可能長時間使用後向式（Rear-facing）座椅，因為這能為脆弱的頸椎與頭部提供最好的支撐，避免發生劇烈減速時的「甩鞭效應」。護理師在衛教時需強調正確安裝與固定方式，並確保安全帶緊貼兒童軀幹。
Car seat safety standards focus on reducing the impact force during a collision. According to the American Academy of Pediatrics (AAP), infants and toddlers should remain in a rear-facing car seat for as long as possible, because it provides optimal support for the fragile cervical spine and head and prevents the whiplash effect during rapid deceleration. When teaching, the nurse must emphasize proper installation and securing and ensure that the harness fits snugly against the child's body.
美國各州對於兒童安全座椅的法律規範（Car Seat Laws）非常嚴格，護理師應指導家長參閱當地的 DMV 或國家公路交通安全管理局（NHTSA）最新指引。
