COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Utilize proper medical notations.

2.  Interpret and compare informational data on drug labels.

3.  Properly interpret drug order and correctly fill prescriptions.

4.  Demonstrate working knowledge in computational pharmacy mathematics.

 

Objectives:

Upon successful completion of this course, students will be able to:

1.   Read and write proper medical notation on the drug order.

2.   Identify information found on drug labels, incuding form, dosage, frequency, and route of administration.

3.   Calculate the oral dosages of drugs, both solid and liquid forms, using ratio-proportion and formula.

4.   Employ critical thinking skills to recognize a "reasonable dose."

5.   Calculate the parenteral dosages of drugs using ratio-proportion and formula.

6.   Reconstitute and label medications supplied in dry or concentrated form.

7.   Differentiate between various directions and select the correct direction for reconstitution.

8.   Calculate the percentage strength and the ratio of concentration.

9.   Calculate standard pediatric dosages.

10. Calculate concentrations and dilutions using volume/volume (V/V), weight/weight (W/W), weight/volume (W/V), and volume/weight (V/W).

11. Calculate dosages using milli-equivalents.

12. Calculate intravenous solution flow rate for electronic and manual infusion systems.

13. Calculate intravenous solution volume and infusion time.
