Course Description

This is designed as a refresher course to help prepare first year registered nursing students for the mathematics competency test taken in RNUR 1129. Topics include systems of measurement, use of formulas, dimensional analysis, solutions, and dosage calculations.

Prerequisite(s) or Corequisite(s)

RNUR 1106 or PMED 2115

Topical Outline
  1. Systems of measurement; Unit conversions
  2. Oral Dosage Calculations; Parenteral Dosage
  3. Reconstitution of solutions; Reconstitution of non-injectable solutions
  4. Pediatric & adult dosages based on body weight
  5. Intravenous solution calculations; Volume-Flow Rate calculations

At the end of this course, students will be able to:

  • Identify symbols and interpret measures in the metric, apothecary and household systems.
  • Convert between units of measurement within the same system.
  • Convert units of measurement from one system to another.
  • Calculate drug dosages using the dimensional analysis method.
