How many milliliters will you administer? 4.

50 milligrams in 1 milliliter of liquid for IM Injection is available. A client is ordered 20 milligrams of Haloperidol decanoate by intramuscular injection. 2.Ĝalculate the drip rate for 2 liters of IV Fluids to be given over 5 hours via a giving set which delivers 10 drops/ml.ģ. Calculate the drip rate for 100 mLs of IV Fluids to be given over a half hour via a giving set which delivers 10 drops/ml.First, think what units will be in the answer.If the pharmacy mixes 20 mg of Milrinone in 100 mL of total solution, what would be the rate of the infusion? Milrinone Lactate (Primacor) has been ordered for a patient at 0.4 mcg/kg/min.Pumps like to be programmed in mL/hr, so mL/hr are your answer units.The standard IV mixture is 450 mg in 250 mL. You need to start a continuous drip of amiodarone at 1 mg per minute (by pump). Always work the problem backwards to check accuracy.Add labels to the appropriately rounded number to get your answer. Round off the calculated answer if possible. Don’t add incorrectly always double check. Multiply all the top numbers together, then divide into that number all the bottom numbers. Same number on top and bottom: these should cancel out b. Simplify the numbers through cancellation. It is time to Solve It: Make sure all the units other than the answer units cancel out, then you are ready to do the math. try picking a different starting factor.Keep trying to cancel out units you don't want until you end up with only the ones you do.This will need to be changed using a cancellation technique.Be aware that the starting factor will always have at least one unit that is not desired.Or pick a factor that is given, such as what the physician ordered.pick from what you know and make sure you put it in the right place.Setup the problem using only what you need to know.Determine what information you already know.Volume (mL) x drop factor gtt (drips)= Rate (gtt/min) (MUST be whole number).The formula for working out flow rates is: To control or adjust the flow rate only drops per minute are used.It must be measured as ml/hour, L/hour or drops/min.

Intravenous fluid must be set for a given rate.When mg/kg/day is ordered, thisis not a division problem, it is a multiplication problem.Dose ordered x desired med (cap, tab, ml) = amount to be given Dose Available.***Remember You may have to perform several conversions before you can obtain the answer you are seeking ***įor oral things like tablets, capsules, etc. If you do not show your work in dosage calculation on the Exams, your answers will be considered wrong !.In any drug calculation problem, for exam purposes, if you do not include the proper unit in your answer it will be WRONG!
