護理師準備為成人進行肌肉注射，哪項行為能減少損傷風險？
A nurse is preparing to administer an intramuscular injection to an adult client. Which nursing action minimizes the risk of injury?
- ASelect the ventrogluteal site to avoid nerves and blood vessels✓ 正解選擇腹臀部位以避免神經和血管
- BUse a 1-inch needle for all adult clients對所有成人病患使用1英吋針頭
- CMassage the site vigorously after the injection注射後用力按摩注射部位
- DAspirate the syringe before injecting the medication注射前抽吸注射器
腹臀肌（Ventrogluteal）部位遠離大血管與神經，是肌肉注射的首選部位。D項在現代護理實證中已不建議抽回血；C項除特定藥物外不應按摩以防刺激；B項針頭長度需視病人體重與皮下脂肪厚度而定，不可一概而論。
The ventrogluteal site is distant from major vessels and nerves and is the preferred site for intramuscular injection. Option D is no longer recommended in current evidence-based nursing practice (aspirating for blood return); option C is incorrect because, except for specific medications, the site should not be massaged to avoid irritation; option B is incorrect because the needle length must be determined by the patient's body weight and subcutaneous fat thickness and cannot be standardized.
美國護理教育極力推廣腹臀部位；台灣傳統教學仍多使用背臀部（Dorsogluteal），近年已開始與國際接軌。
