AIt would stay normal, because insulin is not needed for glucose.
BIt would fall, because the cells use more glucose.
CIt would rise, because less glucose can enter the cells.

At STP (0 °C and 1 atm), what volume does 1 mole of an ideal gas occupy?
温度:°C = (°F − 32) × 5/9,°F = °C × 9/5 + 32。从 °F 换算时先减 32 再乘,从 °C 换算时先乘再加 32。快速核对:37 °C 为 98.6 °F,每 1 °C 相当于 1.8 °F。
乘以 9/5
37.3·9/5 = 67.14
加 32
T = 67.14 + 32 = 99.14 ≈ 99.1 °F
答案
T = 99.1 °F
4.护理数学与单位换算
答案: D = 23.7 mg/h
量纲分析:先写出已知量,再乘以写成分数形式的换算系数(例如 60 min/1 h 或 1 mg/1000 mcg),使每个不需要的单位在分子和分母各出现一次并相互约去。只剩下所求单位时再计算。使用题目给出的等量关系,只对最终答案取整。
列出换算链
D = 5 mcg/kg/min × 79 kg × (60 min/1 h) × (1 mg/1000 mcg)
计算
D = 5·79·60/1000 = 23.7 mg/h
答案
D = 23.7 mg/h
