Student Learning Outcomes/Learning Objectives

 End of Course Outcomes

Solve problems using addition, subtraction, multiplication, and division of whole numbers, mixed numbers, fractions, decimals and percentages; demonstrate conversion from Roman numerals to Arabic numerals and from degrees Centigrade to degreesFahrenheit and vice versa; list the conversion factors for the most frequently used measurement systems in the pharmacy;solve pharmaceutical problems that require conversion between different systems for measurement including household,metric, apothecary, and avoirdupois; calculate the proper dose for an adult or pediatric patient; and calculate the correct flowrate for IV admixtures to deliver the appropriate amount of the drug and/or fluid prescribed.


Learning Objectives

A. Perform addition, subtraction, multiplication, and division of whole numbers, mixed numbers, fractions, and

decimals; perform basic algebraic principles; interpret prescriptions for calculation problems; and convert from

degrees Centigrade to degrees Fahrenheit and vice versa.

 B. Solve basic pharmaceutical problems using ration and proportion.

 C. Convert between the various denominations of each of the basic units in the metric system: meter, liter, and gram, and then use these conversions to solve pharmaceutical problems.

 D. Solve typical pharmaceutical calculation problems requiring the use of common systems.

 E. Solve pharmaceutical problems requiring calculation of percentage strength.

 F. Calculate the amount of stock preparations required to prepare a specified amount of a lesser strength.

 G. Calculate the amount of a lesser strength preparation that can be prepared from a specified amount of a higher strength preparation.

 H. Calculate the amount of diluent which must be added to a specified amount of higher strength preparation to prepare a required lower strength preparation, calculate the proportions of higher and lower strength preparations required for an intermediate strength preparation, and calculate the amount of active ingredient which must be added to make a lower strength preparation to make a desired higher strength preparation.

 I. Calculate the proper dose of a drug for an adult or a child.
