1. What would be the infusion rate for a 50 mg/ml magnesium sulfate solution to provide 1.2 g/hr.?
A. 0.4 ml/hr. B. 2.5 ml/hr. C. 20 ml/hr. D. 24 ml/hr.
1.2 g = 1200 mg/ hour
Use a proportion to calculate the volume to be infused
(50 mg/1 mL = 1200 mg/X mL,
where x has to be identified (x is the flow rate)
50 mg/ 1 ml = 1200 mg / x
X = 1200/ 50 mg
X= 24 ml/ hr
that is 24 ml / hr
SO THE ANSWER IS option D 24 ml/ hour
