護理師準備進行肌肉注射（IM）。對於成年人 1 mL 的藥量，哪一個部位最合適？
A nurse is preparing to administer an intramuscular (IM) injection. Which site is most appropriate for a 1 mL volume injection in an adult?
- ADorsogluteal臀大肌（Dorsogluteal）
- BDeltoid✓ 正解三角肌
- CVastus lateralis股外側肌
- DRectus femoris股直肌
— Explanation · 中文詳解 —
對於 1 mL 或更少的體積，三角肌（Deltoid）是成年人肌肉注射的首選部位。它位置容易取得，且適合小體積注射。背臀部（Dorsogluteal）因鄰近坐骨神經與血管，目前已不建議作為首選注射位置。
The deltoid muscle is the preferred site for intramuscular injections of 1 mL or less in adults due to its accessibility and suitability for small volumes. The dorsogluteal site is no longer recommended because of the risk of injury to the sciatic nerve and major blood vessels.
