Order: Nitroglycerine 50 mg in 250 mL Normal Saline, infuse at 100 mcg/minute. Calculate the rate in mL/h.
A.
2 mL/h
B.
30 mL/h
C.
20 mL/h
D.
0.5 mL/h
Nitroglycerin order is 50 mg/250 ml.
50 mg = 50000 mcg/250 ml.
So, mcg/ml = 200 mcg/ml
100 mcg/min is the rate. So, 0.5ml/ min will be the rate.
To convert into ml/hr rate, multiply 0.5 with 60.
0.5 x 60 = 30 ml/hr.
Option B is the correct answer that is 30 ml/hr.
