護理師指導父母關於 2 歲幼兒的汽車安全座椅使用，應包含哪些內容？（選所有適合的）
Which of the following interventions should the nurse include when teaching parents about car seat safety for a 2-year-old child? (Select all that apply.)
- AThe car seat should be rear-facing until the child reaches the manufacturer's height or weight limit✓ 正解汽車安全座椅應採用後向式安裝，直到兒童達到製造商規定的身高或體重上限
- BThe harness straps should be at or below the level of the child's shoulders束帶應位於或低於兒童的肩膀水平
- CThe chest clip should be positioned at the level of the armpits✓ 正解胸部夾扣應定位於腋窩水平
- DA bulky jacket should be removed before strapping the child in✓ 正解在綁好安全帶之前應脫下厚重的外套
- EThe car seat can be installed in the front seat if the airbag is turned off如果氣囊已關閉，汽車安全座椅可以安裝在前座
後向式安裝能保護幼兒頭頸部，應維持至座椅限制的極限（選項 A 正確）。胸扣必須位於腋下高度以確保胸腔穩定（選項 C 正確）。厚重外套會影響安全帶緊密度，導致碰撞時滑脫，必須移除（選項 D 正確）。選項 B 錯誤：後向式安全帶應低於或平於肩部，但在前向式時需高於肩部，2 歲通常已轉為前向，故此敘述不夠精確且易混淆。選項 E 錯誤：兒童應一律坐後座。
Rear-facing installation protects an infant's head and neck and should be maintained until the seat's height or weight limits are reached (option A correct). The chest clip must be positioned at armpit level to stabilize the chest (option C correct). Heavy outerwear interferes with harness tightness and can allow the child to slip out during a crash, and must therefore be removed (option D correct). Option B is incorrect: in a rear-facing seat, harness straps should be at or below the shoulders, while in a forward-facing seat they should be above the shoulders; at 2 years of age the child is generally already forward-facing, so this statement is imprecise and easily confused. Option E is incorrect because children should always be placed in the back seat.
美國法規對後向式要求較嚴格；台灣法規對於幼兒乘坐位置的規定較寬鬆，建議依循國際安全標準。
