The purpose of this interactive tutorial is to assist
healthcare professionals to renew their math skills and/or learn to calculate
medication dosages and IV rates. It is organized in multiple sections or
chapters within each module, with a total of 3 modules, and at the end of each
module, there is a final quiz for that module. The three modules are: Module 1)
Introduction to fractions, decimals, ratios, and proportions; Module 2) Metric,
apothecary weight, and liquid volume conversions; Module 3) IV flow rate
This learning resource is interactive with animated
graphics, including an animated graphic displaying microdrop and macrodrop
illustrations in the third module. Short quizzes provide immediate feedback for
the correct answer and the rationale. Learning assignments proceed in logical
order with one building on the next. Within each assignment, steps for
calculations are presented from the beginning of each type of problem to the
end. Although there is no section entitled glossary of terms, the introduction
for each module has terminologies with definitions included. Target Populations
Nurses and nursing students. This learning resource would be appropriate not
only for RNs and professional nursing students but also for LPNs and LPN
students as well.
Prerequisite skills The author suggests that the learner
perform the calculations without a calculator, so the learner needs to have a
basic understanding of math.
Key words: Medication Calculation, Math, IV Flow Rate
The user needs to have a computer connected to the
Internet. The author makes the following recommendations for use
* Windows 2000 or XP
* Mac OS 9 or Mac OS X
* Minimum 64 MB RAM, 1 G of free disk space
* 150 MHz or higher processing speed
* 56K modem or better
* Monitor capable of at least 800 x 600 resolution
* Install anti-virus software
* Download and install Java 1.4.2 (http://www.java.com).
* Disable any "pop-up blocker" software that you have installed on
* Set your screen resolution at 1024 x 768 pixels, for optimum
There are separate learning goals for each of the three
Module 1: Following the completion of the first module,
the learner will be able to demonstrate an understanding of how to: 1) Multiply
and divide decimal numbers and fractions, while expressing answers to the
nearest tenth. 2) Calculate simple dosage problems using ratio and proportion.
3) Convert percentages to decimals, fractions, and ratio and proportion.
Module 2: Following the completion of Module 2, the
learner should be able to: 1) Interpret metric, apothecary, and household
systems of measurement ; 2) Illustrate the steps involved in interpreting
pharmaceutical company medication labels. 3) Identify the "six rights" of
medication administration 4) Differentiate two methods of medication dosage
calculation 5) Carry out medication dosage calculations using "basic formula"
and "fractional equation" methods.
Module 3: Following the
completion of Module 3, the learner should be able to: 1) Recognize
calibrations in drops (gtts)/mL on IV administration sets.
2) Calculate IV infusion times and
flow rates using the two-step formula method.
3) Calculate the amount of time
necessary to infuse a medication per direct IV infusion ("IV Push.")
4) Identify safety considerations
related to monitoring a client receiving IV therapy.
