| What
is Pharmacology Math? |
Nurses
must perform dosage calculations when administering medications and intravenous
fluids. Pharmacology math requires the nurse to know systems of
measurement (metric, household, apothecary, and avoirdupois) and how to
convert within those systems of measurement. Other system of measurements
include units (common for insulin and heparin), milliequivalents (mEq)
(common for some drugs such as potassium chloride), and international
units (IU) (common for vitamins). Since nurses need to accurately
calculate medication dosages, it is essential to understand drug weights
and measures.
Math computation skills (addition, subtraction, division, multiplication, fractions, etc) are necessary to calculate medication dosages. To interpret physician's orders, the nurse must also understand abbreviations used to describe those units of measurement and frequency of administration. Other instances in which the nurse may use math (pharmacology) includes calculating safe dosages of medications. Nurses
may use basic math to determine intake and output. |
