護理師準備對一名 10 個月大的嬰兒進行肌肉注射。請問下列哪個部位最適合？
A nurse is preparing to administer an intramuscular injection to a 10-month-old infant. Which site is the most appropriate for this procedure?
- AVastus lateralis muscle✓ 正解股外側肌
- BVentrogluteal muscle腹臀部
- CDeltoid muscle三角肌
- DDorsogluteal muscle背臀部

對於 1 歲以下的嬰兒，股外側肌（Vastus lateralis）是首選注射部位。此部位肌肉發育最完全且遠離大型血管與神經。三角肌需在兒童發展出足夠肌肉量後才考慮使用。臀部注射在嬰兒時期因坐骨神經損傷風險高且肌肉尚未發展成熟，應絕對避免。
For infants under 1 year old, the vastus lateralis is the preferred injection site. This muscle is the most developed in this age group and is away from major blood vessels and nerves. The deltoid muscle can only be considered after the child has developed sufficient muscle mass. Gluteal injection in infants must be absolutely avoided because of the high risk of sciatic nerve injury and immature muscle development.
✦ 台美臨床差異
台美臨床實務皆遵循此肌肉發展原則，但台灣部分基層診所仍有極少數採臀部注射之舊習慣。
