Given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.
Rate of prescribed dose by IV: [tex]2.10*10^2 ug/min = 210ug/min[/tex]
Available: [tex]50mg nitroglycerine = 50000ug[/tex]
Available Volume: [tex]150mL[/tex]
Hence, [tex]50000ug = 250ml[/tex]
and volume for [tex]210ug = x[/tex]
We cross multiply to find x
[tex]x = \frac{210ug * 250mL}{50000ug} \\\\x = 1.05mL[/tex]
Meaning that in a single minute, 1.05mL is been infused into the patient
Now, for an hour, ( 60 minutes ) the volume infused will be;
[tex]1min = 1.05mL[/tex]
[tex]60min = x[/tex]
We cross multiply to find x
[tex]x = \frac{1.05mL*60min}{1min}\\\\x = 63mL[/tex]
Therefore, given the flow rate and the amount of nitroglycerine contained in the IV bag, the patient should receive 63 milliliters per hours.
