護理師準備進行肌肉注射，在成人個案中，哪個部位最能避免損傷坐骨神經？
A nurse is preparing to administer an intramuscular injection. Which site is preferred to prevent damage to the sciatic nerve in an adult client?
- ADorsogluteal site背臀部部位
- BRectus femoris股直肌
- CVentrogluteal site✓ 正解腹臀部部位
- DDeltoid site三角肌部位
腹臀部（Ventrogluteal site）肌肉注射被認為是成人最安全、最推薦的部位。該部位位於臀中肌與臀小肌，遠離坐骨神經、主要血管與骨骼突起，且肌肉層厚實，適合各種體型的病人，包括肥胖者。相比之下，背臀部（Dorsogluteal site）因鄰近坐骨神經，注射風險較高，已逐漸在現代護理實務中被淘汰。
The ventrogluteal site is considered the safest and most recommended intramuscular injection site in adults. It is located between the gluteus medius and gluteus minimus, away from the sciatic nerve, major blood vessels, and bony prominences, and has a thick muscle layer, making it appropriate for clients of all body types, including those who are obese. In contrast, the dorsogluteal site, because of its proximity to the sciatic nerve, carries a higher risk and has been progressively phased out of modern nursing practice.
