Question

order nitroglycerin 50mg in 250ml normal saline, infuse at
10mcg/min. calculate the rate in ml/hr. round answer to whole
number

Answer #1

**order nitroglycerin = 50mg in 250ml**

**Infuse rate given. = 10mcg/min**

**Infuse rate Hourly. = (10mcg/min) * 60**

**= 600mcg/60min**

**= 600mcg/hr**

**1 mg = 1000 mcg**

**There for, 600mcg = 0.6mg/ hr**

**Total order. = 50gm in 250ml**

**= 1gm in 5ml**

**= 0.1gm in 0.5ml**

**Infusion rate in mg/hr. (We found that in first part) =
0.6mg/hr**

We know, 0.1gm in 0.5ml

There for,

**Infusion rate at ml/hr = (0.1 in 0.5ml) *
0.6mg/hr**

**= 0.6mg in 0.3ml**

INFUSION RATE = 0.3ml / hr

Answer : **0.3 ml / hr**
