Introductory Course in Medical Math


Calculating and preparing medications for others properly and safely is a top priority for healthcare professionals. Nurses and allied health professionals must sensibly solve medication calculation problems and use rational judgment when determining patient dosages. Healthcare professionals may make drug errors unknowingly by depending solely on the calculation without first determining what the dosage should be. Using critical thinking skills helps in this determination. For example, you should question any calculation that would total a questionable amount such as administering 12 tablets of a medication.

Medical Math is designed to assist you with using critical thinking skills, understanding medication orders, equipment used in medication preparation and administrating, and drug labels in addition to calculating dosages administered oral and parenteral routes using the 3 systems of measurement.

This course includes instructor presentations, quizzes, tests, and textbook. Included with the textbook is a resource CD with calculation exercises and quizzes.
