護理師準備對一名 10 個月大的嬰兒進行肌肉注射，哪一個部位最為適合？
A nurse is preparing to administer an intramuscular injection to a 10-month-old infant. Which site is the most appropriate for the nurse to use?
- ADeltoid三角肌
- BVastus lateralis✓ 正解股外側肌
- CVentrogluteal腹臀肌
- DDorsogluteal臀背側肌
— Explanation · 中文詳解 —
根據疫苗注射與藥物給藥準則，嬰兒的股外側肌（Vastus lateralis）發育最為完全，是肌肉注射的首選部位。三角肌在嬰兒時期肌肉量不足，臀部肌肉則因為行走前的神經發育尚未完全，應避免注射以防損傷坐骨神經。
The vastus lateralis is the most appropriate site for intramuscular injections in infants because it is the largest and most developed muscle in this age group. Other sites like the deltoid are underdeveloped, and gluteal muscles are avoided due to the risk of sciatic nerve injury before walking begins.
