護理師教育家長關於 6 個月大嬰兒的安全照護，哪項指導最重要？
A nurse is educating a parent on safety for a 6-month-old infant. Which instruction is highest priority?
- AIntroduce cow's milk to the diet在飲食中引入牛奶
- BEnsure the crib mattress is firm and free of soft objects✓ 正解確保嬰兒床墊堅硬且無柔軟物品
- CPlace the infant on their stomach to sleep讓嬰兒採仰臥姿勢睡覺
- DUse a rear-facing car seat until age 5使用朝後安裝的汽車安全座椅直至 5 歲
預防嬰兒猝死症候群（SIDS）的核心在於睡眠環境安全。嬰兒床必須淨空，移除枕頭、填充玩具與厚毯子，且床墊需硬實。C 錯誤：嬰兒應仰睡。A 錯誤：1 歲前不可飲用牛奶。D 錯誤：後向式安全座椅通常建議至少使用至 2 歲或達到製造商身高體重上限，雖有彈性但非最緊急的睡眠死亡風險防範。
The core of sudden infant death syndrome (SIDS) prevention is sleep environment safety. The crib must be kept clear, with pillows, stuffed toys, and heavy blankets removed, and a firm mattress is required. C is incorrect: infants should sleep on their backs. A is incorrect: cow's milk should not be given before 1 year of age. D is incorrect: rear-facing car seats are generally recommended at least until age 2 or until the manufacturer's height and weight limits are reached; although there is some flexibility, this is not the most urgent measure for preventing sleep-related death.
美國 AAP 對 SIDS 指引極度嚴格；台灣兒科醫師同樣強調仰睡及淨空床鋪，但家庭結構不同，有時需提醒家長避免與嬰兒同床（Bed-sharing）。
