一位病人被處方一個療程的抗生素。護理師應教導病人，何時可能產生抗生素抗藥性？（選所有適合的）
A client is prescribed a course of antibiotics. The nurse should teach the client that antibiotic resistance can develop when:
- AThe client stops taking the medication once symptoms improve.✓ 正解症狀改善後停止服藥
- BThe client takes the antibiotic for a viral infection.✓ 正解為病毒性感染服用抗生素
- CThe client shares their antibiotics with someone else.✓ 正解將抗生素分享給他人
- DThe client takes the antibiotic with food.隨餐服用抗生素
- EThe client misses a dose occasionally.✓ 正解偶爾遺漏一劑
抗生素抗藥性會在不適當使用時產生：A. 過早停藥使殘餘細菌有機會產生抗藥性；B. 用於病毒感染（抗生素對病毒無效，反而破壞正常菌群並選擇出抗藥菌）；C. 分享抗生素為標準抗生素濫用，未經診斷與處方使用會直接促進抗藥性發展；E. 錯過劑量導致藥物濃度不足以殺菌，但仍夠強到篩選出抗藥菌。錯誤：D. 隨餐服藥多為改善吸收與耐受性，與抗藥性無關。
Antibiotic resistance develops with inappropriate use: A. Stopping the medication early gives residual bacteria the opportunity to develop resistance; B. Using antibiotics for a viral infection (antibiotics are ineffective against viruses, and their use disrupts normal flora and selects for resistant organisms); C. Sharing antibiotics is standard antibiotic misuse — use without proper diagnosis and prescription directly promotes resistance; E. Missed doses result in sub-therapeutic drug levels that cannot kill bacteria but are still high enough to select for resistant strains. Incorrect: D. Taking antibiotics with food usually improves absorption and tolerance and is unrelated to resistance.
美國的公眾衛生宣導常強調「剩餘抗生素不可服用」；台灣的宣導則更關注「依醫囑完成療程」。
