F-32) X 5/9 (fraction)
A formula used to determine an appropriate pediatric dose by using the child's age in years and the normal adult dose; [age in years/(age in years + 12 years)] X adult dose= pediatric dose
A formula used to determine an appropriate pediatric dose by using the child's weight in pounds and the normal adult dose; weight in lb/150 lb X adult dose= the pediatric dose
A numerical representation of the relationship between two parts of the whole or between one part and the whole
An expression of equality between two ratios
The concentration obtained when two or more solutions of different strengths are combined
IV Piggyback (IVPB)
A small volume of fluid and medication that is given intravenously in addition to a primary infusion over a short period of time
Weight in weight (w/w)
number of grams in the drug in 100 g of the final product
x g drug/100 g product
Weight in volume (w/v)
number of grams in the drug in 100 ml of the final product
x g drug/100 mL product
Volume in volume (v/v)
number of milliliters of the drug in 100 mL of the final product
x mL drug/100 mL product
Weight-in-weight problems involve mixing two solids, such as a dry powder and a cream
percentage strength of w/wsolution = g of active ingredient/100 g of final product x 100
Weight-in-volume problems involve adding a solid drug to a liquid, such as a powder dissolved in a syrup.
percentage strength of w/v solution = g of active ingredient/100 mL solution x 100
Volume-in volume problems involve mixing a pure liquid and another liquid, such as pure alcohol or water.
percentage strength of v/v solution = mL of active ingredient/100 mL solution x 100
IV flow rates
When calculating the duration of therapy, always round your answer down to the whole hour.
duration of therapy formula
duration of therapy = volume of fluid or amount of drug to be infused/flow rate
