護理師準備為嬰兒進行肌肉注射，下列哪個部位是該年齡層的首選？
A nurse is preparing to administer an intramuscular injection to an infant. Which site is preferred for this age group?
- AVentrogluteal muscle腹臀肌
- BVastus lateralis muscle✓ 正解股外側肌
- CDorsogluteal muscle背臀肌
- DDeltoid muscle三角肌
— Explanation · 中文詳解 —
嬰兒的臀部肌肉尚未發育完全，若注射在背臀肌（dorsogluteal）極易損傷坐骨神經。股外側肌（vastus lateralis）位於大腿前外側，肌肉量大且無重要神經血管，是嬰兒及幼童肌肉注射的最安全選擇。
The vastus lateralis muscle is the preferred site for intramuscular injections in infants because it is well-developed and free of major nerves and blood vessels. Other sites like the dorsogluteal muscle are contraindicated due to the risk of sciatic nerve injury, and the deltoid is often too small for adequate volume.
