## 深入解析

快速解答
C。C 長度為1.5英吋、23號針頭，符合此個案的兩項條件。
為何這是最佳選擇
對於體重超過90公斤的女性，CDC建議成人肌肉注射疫苗使用1.5英吋針頭；針頭號數範圍為22–25。請同時閱讀一般尺規與針座標籤。
臨床情境
這些觀察資料為虛構的教學數據。請應用所述情境；所選特徵本身不能取代完整的床邊評估。
記憶口訣
針頭長度與號數是分開的要求；滿足其中一項不代表同時滿足兩項。
決策規則
針頭長度與號數是分開的要求；滿足其中一項不代表同時滿足兩項。
為何其他區域不合適
A 長度適當但為21號，超出建議疫苗接種範圍。B 為23號但長度僅1英吋。D 為25號但長度僅5/8英吋。
**資料來源**
- 成人肌肉注射疫苗針頭選擇需考量號數、性別與體重。

## 重要概念

- **Needle length and gauge jointly determine suitability** — 針頭長度與號數是分開的要求；滿足其中一項不代表同時滿足兩項。
- **Comparison with context** — A 符合長度，B 符合號數；只有 C 同時符合此個案的兩項條件。
