*Solve the question with arbitrary number* Thank you!
A hospital pharmacist receives the following order for an intravenous admixture: Dopamine 600 mg in 500 mL D5W.
(a). How many milliliters of an (a given #) mg/mL solution of dopamine would be needed to prepare this admixture?(Answer to the nearest tenth of mL – one decimal point)
(b). The required initial dose of dopamine is 4 mcg/kg/min, and this solution is to be administered to a patient weighing 154 pounds using an administration set with a drop factor of (a given #) drops/mL. What would be the flow rate (gtts/min) for this patient? (Answer to the nearest full drop – no decimal point)
Explanation / Answer
Hospital pharmacist receives the following order for an intravenous admixture: Dopamine 600 mg in 500 mL D5W.
a. 1.2 mg per 1 mL.
as per above condition 600 mg in 500 ml D5W.
so
= 600 mg /500 mL
=1.2 mg in 1 mL.
b. 14
formula
First, convert mcg/kg/min into mg/hr.
In the above, the dose would be 16.76 mg/hr.
the 154 pounds is equval to 69.85 Kgs, so
Next, use the dopamine dosage formula to solve the rest of the problem.
16.76mg is the dose ordered,
600 mg is the dose available in 500 mL volume.
.
this convert into per minute
=13.96 /60
=0.23 gett/min.
