護理師準備進行肌肉注射。為了維護安全，最重要步驟為何？
A nurse is preparing to administer an IM injection. To maintain safety, what is the most important step?
- AVerify client identity using two identifiers✓ 正解使用兩項識別標誌驗證病人身份
- BAspirate before injecting the medication注射前進行抽吸
- CUse the Z-track method使用Z字路徑注射法
- DRecap the needle immediately after injection注射後立即重新套回針蓋
給藥安全是病人安全目標（National Patient Safety Goals, NPSG）的核心。肌肉注射（IM injection）雖包含技術操作（如 Z-track），但 NCLEX 考題中，預防醫療錯誤永遠是首要任務。確認病人身份（Two Identifiers）是防止錯誤給藥的最後一道防線，必須在任何給藥介入前執行。
Splitting is a defense mechanism in borderline personality disorder where clients idealize or devalue staff to create conflict. The most appropriate nursing action is to collaborate with the healthcare team to ensure a consistent, unified approach to care, preventing the client from manipulating staff differences and reinforcing the need for objective limit-setting rather than emotional engagement or punishment.
美國醫療機構嚴格執行「雙重身份確認」，且對於口頭醫囑（Verbal orders）有極嚴格的 Read-back 規範。此外，美國護理師極度重視針扎安全，針具皆配有自動安全鎖定裝置。
