Reason and problem solve while working through an in-depth tutorial and real-life scenarios at your own pace. By pairing easy-to-use and easy-to-understand programs with classroom content, you gain the understanding and practice necessary to boost your confidence in medical calculations and in nursing proficiency.

Interactive drills, embedded videos, and case studies enrich real-life scenarios, providing valuable experience for building competence to administer medications safely. Mathematical equations are simplified through step-by-step animations that demonstrate the dosage calculation process using three different calculation methods.

 

The Desired Over Have method allows a nurse to calculate dosages by using the amount of medication prescribed and the dose available. For example, a client is prescribed haloperidol 1 mg PO BID and the dose available is 0.5 mg/tablet.  The desired amount is 1 mg, the dose available is 0.5 mg and the quantity available is 1 tablet. Use the following formula to calculate dosages using the Desired Over Have method.

 

Have    =  Desire

Quantity        X

 

The Dimensional Analysis method allows a nurse to calculate dosages by using a series of ratios and factors, organized in the form of fractions that are then multiplied. The nurse must know the unit of measure being calculated, the amount of medication prescribed and the dose available. Equations involving multiple factors are arranged so that the unit of measurement in the denominator of one factor is placed in the numerator of the following factor and so on. Unwanted units are then cancelled. For example, a client is prescribed haloperidol 1 mg PO BID and the dose available is 0.5 mg/tablet.  The desired amount is 1 mg, the dose available is 0.5 mg and the quantity available is 1 tablet. Use the following formula to calculate dosages using the Dimensional Analysis method.

 

Unit of measure = Quantity   x   Desired Dose

Have       1
Tablet = 1 tab   x   1 mg
0.5 mg         1

 


Ratio and Proportion method allows a nurse to calculate dosages by using the amount of medication prescribed and the dose available. For example, a client is prescribed haloperidol 1 mg PO BID and the dose available is 0.5 mg/tablet.  The desired amount is 1 mg, the dose available is 0.5 mg and the quantity available is 1 tablet. Use the following formula to calculate dosages using the Ratio and Proportion method.

 

Desired  x Quantity = Amount to be given
Have     1 mg x 1 tab = x tablets
0.5 mg
