Description

Applied mathematics as a fundamental communication and technical skill. Review of calculations involving fractions, decimals, ratios and proportions, unit conversions, and algebraic equations. Clinical medical calculations utilized in preparation and administration of drugs, dosage determinations, intravenous fluid infusion, and prescription dispensing.

Course Objectives

The student will be able to:
A. Perform calculations involving ratios, proportions, and ratio fractions.
B. Perform conversions between decimals, fractions, ratios, and percentages.
C. Perform conversions between metric and household systems of measure.
D. Interpret oral and parenteral medication labels involving capsule and tablet strength dosages, oral solution concentrations, international units, milliequivalents, and weight-to-volume percentage concentrations.
E. Perform calculations relating percentage, ratio strength, and concentrations of solutions.
F. Perform calculations of dosages of drugs, and dispensing of drug quantities from dosage calculations.
G. Record drug administration information in medical records, such as patient records, controlled substances logs, anesthesia logs, and prescription labels.
H. Perform calculations involving intravenous preparations, including consideration of isotonicity, milliequivalents, percentage solutions, flow (drip) rates, and constant infusions.
