護理師教導家長關於兒童安全帶的安全須知。兒童何時可以轉用一般安全帶？
A nurse is teaching a parent about child safety regarding seat belts. When can a child transition to a regular seat belt?
- AWhen they reach the age of 8當他們達到8歲時
- BWhen they start school當他們開始上學時
- CWhen they are 4 feet 9 inches (145 cm) tall✓ 正解當他們身高達到4英尺9英寸（145公分）時
- DWhen they weigh 60 pounds當他們體重達到60磅時
兒童轉用成人安全帶的時機並非僅由年齡或體重決定，關鍵在於「安全帶的貼合度」。美國公路交通安全管理局（NHTSA）建議，兒童必須達到 4 呎 9 吋（約 145 公分）的身高，才能確保安全帶正確跨過骨盆（而非腹部）與肩膀（而非頸部）。若身高不足，安全帶會壓迫腹部或頸部，發生碰撞時反而會造成嚴重的內臟或頸椎傷害。
The timing for a child to transition to an adult seat belt is not determined solely by age or weight; the key is the 'fit of the seat belt.' The U.S. National Highway Traffic Safety Administration (NHTSA) recommends that a child reach a height of 4 feet 9 inches (about 145 cm) before using a regular seat belt, to ensure that the belt sits correctly across the pelvis (not the abdomen) and across the shoulder (not the neck). If the child is too short, the belt will compress the abdomen or neck, and in the event of a crash this can cause serious visceral or cervical spine injury.
台灣法規對於兒童安全座椅的使用年齡規定與美國接近，但美國 NCLEX 考試中，NHTSA 的 4 呎 9 吋標準是絕對考點，臨床上護理師需強調「檢查安全帶是否跨過大腿骨與肩膀」的重要性。
