護理師教導病人正確洗手技術，應包含哪些內容？（選所有適合的）
A nurse is teaching a client about proper handwashing technique. What should be included? (Select all that apply.)
- AUse warm water✓ 正解使用溫水
- BRub hands together for at least 20 seconds✓ 正解雙手搓揉至少20秒
- CKeep hands lower than elbows保持手部低於手肘
- DTurn off the faucet with a clean paper towel✓ 正解用乾淨的紙巾關閉水龍頭
- EApply soap only to the palms僅將肥皂塗抹於手掌
依 CDC 一般洗手（routine handwashing）標準：A. 使用溫水（warm water）有助起泡與舒適；B. 搓揉雙手至少 20 秒以物理移除微生物；D. 用乾淨紙巾關水龍頭以避免接觸污染表面。錯誤：C. 「手部低於手肘」是外科無菌洗手（surgical hand scrub）的原則，目的是讓污水從手指流向手肘排出（外科洗手手部反而要高於手肘），與一般洗手無關；E. 肥皂應覆蓋所有手部表面（手掌、手背、指縫、指甲下），僅塗手掌不足。
According to CDC standards for routine handwashing: A. Use warm water, which aids lathering and is comfortable. B. Rub the hands together for at least 20 seconds to mechanically remove microorganisms. D. Turn off the faucet with a clean paper towel to avoid touching a contaminated surface. Incorrect options: C. Keeping the hands lower than the elbows is a principle of surgical hand scrub, designed to allow contaminated water to flow from the fingers toward the elbows (in surgical hand scrubs, the hands must in fact be held higher than the elbows), and is not applicable to routine handwashing. E. Soap must cover all surfaces of the hands (palms, backs of the hands, between the fingers, and under the nails); applying soap only to the palms is insufficient.
正確洗手技術的教學內容和標準在美國和台灣是完全一致的，都遵循 CDC 和 WHO 的指引。這包括使用溫水、搓揉至少 20 秒、涵蓋所有手部表面、以及用乾淨紙巾關閉水龍頭。這些原則是全球通用的感染控制標準。此部分無顯著差異。
