- AUsing two patient identifiers before every medication administration✓ 正解每次給藥前使用兩項病人識別資訊

- CClarifying a medication order that contains ambiguous abbreviations✓ 正解澄清含有模糊縮寫的藥物醫囑

用藥安全是 NCLEX 考試中「安全與感染控制」領域的核心。護理師在給藥前須遵循「三讀五對」原則（或美國常見的 Rights of Medication Administration），並確保溝通清晰與紀錄精確。緩釋劑型（Extended-release）的藥物結構設計是為了緩慢釋放藥物，磨碎會導致藥物瞬間大量進入血液循環，造成毒性反應。
Medication safety is a core topic within the 'Safety and Infection Control' domain of the NCLEX. Before administration, the nurse must follow the Rights of Medication Administration and ensure clear communication and accurate documentation. Extended-release formulations are designed to release medication slowly; crushing them allows a large amount of drug to enter the circulation at once, causing toxicity.
美國醫療體系全面推行電子給藥系統（BCMA），掃描病人腕帶與藥物條碼是強制性步驟，台灣雖亦推廣，但美國執行力與法律責任規範更為嚴謹。
