A nurse is teaching a new mother about bottle feeding. Which instructions should be included? (Select all that apply.)
- ADiscard leftover formula after one hour✓ 正解一小時後丟棄剩餘配方奶
- BMicrowave formula to heat it quickly使用微波爐快速加熱配方奶
- CTest the temperature of the formula on the inner wrist✓ 正解在手腕內側測試配方奶溫度
- DKeep the bottle tilted to keep the nipple full of formula✓ 正解保持奶瓶傾斜以使奶嘴充滿配方奶
- ESterilize bottles before first use✓ 正解首次使用前對奶瓶進行消毒
瓶餵衛教的核心在於預防細菌感染與確保餵食安全。配方奶在室溫下極易滋生細菌，剩餘奶水應於 1 小時內丟棄。微波加熱會導致奶水受熱不均，形成隱藏的熱點（hot spots），極易造成嬰兒口腔嚴重燙傷。測試溫度應在手腕內側，利用該處敏感皮膚感知溫度。餵食時奶瓶保持傾斜可確保奶嘴充滿奶水，減少嬰兒吸入空氣導致脹氣。初次使用奶瓶需徹底消毒以確保衛生。
Bottle-feeding education focuses on preventing bacterial infection and ensuring feeding safety. Formula grows bacteria quickly at room temperature; leftover formula should be discarded within 1 hour. Microwave heating causes uneven heat and hot spots that can severely burn the infant's mouth. Temperature should be tested on the inner wrist using sensitive skin. Tilting the bottle so the nipple remains full of formula reduces air intake and gas. New bottles need to be sterilized before first use.
