護理師為學生舉辦個人衛生衛教，應強調哪點？
A nurse is teaching a community class about personal hygiene for students. Which of the following should the nurse emphasize?
- AShowering once a week每週淋浴一次
- BHandwashing with soap for 20 seconds✓ 正解用肥皂洗手 20 秒
- CBrushing teeth only when visible food is present僅在有可見食物殘渣時刷牙

個人衛生是預防傳染病傳播的基礎。護理師在衛教時應強調手部衛生的正確技巧與時機。正確洗手能有效去除手部暫時性菌叢，是控制交叉感染最簡單且低成本的手段。根據 CDC 指引，使用肥皂和水洗手至少 20 秒能有效清除病原體。其他選項如共用個人物品會增加傳染病散播風險，而刷牙與沐浴頻率則需維持適當的個人衛生習慣，不可隨意簡化。
Personal hygiene is foundational to preventing the spread of communicable disease. When teaching, the nurse should emphasize proper hand hygiene technique and timing. Correct handwashing effectively removes transient flora from the hands and is the simplest and most cost-effective means of controlling cross-infection. According to CDC guidelines, washing the hands with soap and water for at least 20 seconds effectively removes pathogens. Other options, such as sharing personal items, increase the risk of communicable disease transmission, while tooth-brushing and bathing frequency must maintain appropriate hygienic habits and should not be casually reduced.
