Ordered: 50 mg of nitroprusside in 250 D5W to deliver 2 mcg/kg/min to a 148 lb patient.The infusion pump should be set at ________. (Round to the nearest tenth)
Fill in the blank(s) with the appropriate word(s).
40.4 mL/h
Convert 148 lb to kg:
1 kg : 2.2 lb = x : 148 lb
x = 67.27 kg, rounded to 67.3 kg
Convert mg to mcg:
1,000 mcg : 1 mg = x : 50 mg
x = 1,000 mcg × 50
x = 50,000 mcg
Determine the desired dose:
D = 2 mcg/kg × 67.3 kg = 134.6 mcg/min
Calculate amount to administer per minute:
H = 200 mcg; Q = 1 mL; D = 134.6 mcg
A = 0.673 mL/min
Convert to mL/h:
A = 40.38 mL/h, rounded to 40.4 mL/h
