Course Description

Introduces mathematics as applied to pharmacology. Includes unit conversions, solutions and percentage calculations, and drug dosage calculations.

Addendum to Course Description

The purpose of this course is to teach the veterinary technology student the fundamentals of pharmaceutical mathematics.  This is designed for first-year veterinary technology students and is a graduation requirement for the Associates Degree in Applied Sciences in Veterinary Technology.  Credits in this course are not transferable to a four year school towards a baccalaureate degree. No text is required for this course.

Intended Outcomes for the course

Upon successful completion of the course, the student will be able to:

  • Accurately calculate veterinary drug dosages and convert between units.
  • Accurately calculate temperature conversions between Celsius and Fahrenheit.
  • Recognize the physical forms of drugs and equipment used in drug measurement.
  • Describe methods and equipment used in medicating animals by oral and parenteral administration.
  • Read drug labels and interpret a veterinarian's drug orders as well as create labels for veterinary client use.
  • Define symbols and abbreviations used in prescription writing.
  • Read and write a prescription and its component parts, under the order of a veterinarian.
  • Calculate percentages of solutions for diluting and mixing purposes.
  • Determine and maintain IV fluid infusion rates for veterinary patients.
  • Recognize and understand the use of IV fluid types and the delivery systems used.

Course Activities and Design

This course is designed to be a lecture course.  It is a one credit-hour course that meets for one lecture-hour per week.  Topics will include unit conversions, solutions and percentage calculations, alligation, drug dosage calculations and basic fluid therapy.

Outcome Assessment Strategies

Grading will be based upon student understanding of the course content as demonstrated by periodic examinations, homework assignments, quizzes, a comprehensive final exam and attendance. To be eligible for a passing grade, the student must have attended a minimum of 80 percent of each of the lecture and lab classes

Course Content (Themes, Concepts, Issues and Skills)

Content labeled with an asterisk indicates content required by our accreditor.  Content that is also italisized indicates tasks that the student must be able to perform since they are listed as “essential tasks” by the Accreditation Policies and Procedures of the American Veterinary Medical Association's Committee on Veterinary Technician Education and Activities.

1.0   DOSAGE CALCULATIONS AND CONVERSIONS

INSTRUCTIONAL GOAL:

The goal is for the student to develop a proficient working knowledge of calculating drug dosages and converting between units of the metric, apothecaries and household systems using the label factor method (dimensional analysis).

OBJECTIVES:

1.1 Review basic math as it applies to the metric system.

1.2 Define the following units and abbreviations:

     a. gram Gm or g

     b. milligram mg

     c. microgram ug

     d. kilogram kg

     e. liter L

     f. milliliter ml or cc

     g. minim m

     h. grain gr

     i. pound lb

     j. dram dr

     k. ounce oz

     l. pint pt

     m. quart qt

     n. drop gt

     o. teaspoon tsp

     p. tablespoon tbsp

     q. units u

     r. milliequivalent meq

1.3 Know the approximate equivalents:

     a. 65 milligrams= 1 grain

     b. 1 gram=1000 miligrams= 15 grains

     c. 15 grams= 4 drams= 1 tablespoon= 3 teaspoons= 15 milliliters

     d. 30 grams= 1 ounce= 2 tablespoons = 30 milliliters

     e. 16 ounces= 1 pound=454 grams

     f. 1 kilogram= 1000 grams= 2.2 pounds

     g. 1 milliliter= 15 minims= 15 drops

     h. 1 quart= 946 milliliters

     i. 1 pint= 473 milliliters

     j. 1 milligram= 1000 micrograms

1.4 Define and perform the steps in applying the label factor method to conversion between metric, apothecaries and household systems.

1.5 Be able to convert between Celsius and Fahrenheit temperature.

1.6 Be able to calculate drug dosages in dry or liquid measure based on body weight.
