Highlights

Dimensional analysis is a problem-solving technique used in nursing to solve drug dosage calculation problems.

Before starting dimensional analysis, one must learn the metric table.

A copy of the metric table can be found on the website registernurse.com/metric-table.

The metric table is in Microsoft Docx format for easy printing and reference.

Dimensional analysis allows solving for any values by multiplying them by one without changing the value.

The process involves setting up the problem by identifying the desired unit of measurement.

Problems are worked diagonally in dimensional analysis, canceling out the unwanted unit.

An example problem: 8 grams equals 8,000 milligrams when converting using the metric table.

For more complex conversions, multiple steps may be required, such as converting grams to micrograms.

When converting 8 grams to micrograms, the result is 8 million micrograms.

Another example involves converting 100 milliliters to ounces using dimensional analysis.

The conversion of 100 milliliters to ounces results in 3 ounces.

Dimensional analysis makes drug and dosage calculation easier once mastered.

RegisterNurseRN.com offers practice quizzes for nursing students to test their understanding of dimensional analysis.
