Dimensional analysis is an easy problem-solving method to use to solve basic metric conversion problems. On the NCLEX exam, you may be expected to solve some dosage and calculation problems. In addition, you will be required to demonstrate proficiency in drug solving problems in nursing school and before you start work as a registered nurse or licensed practical nurse administering drugs.
Solving basic metric conversions is the first step in learning how to solve actual drug problems. You must first grasp how to solve the problems below before you attempt to solve more complex dosage problems.
How to Use Dimensional Analysis in Metric Conversions
Here is a video tutorial on how to solve the following basic metric conversion problems listed below. You can print the worksheet and follow Sarah as she solves the problems. Below are written out steps on how to solve the problems.
After you are done watching this video tutorial, test your knowledge by taking the basic metric conversion quiz.
Basic Metric Conversions Solved using Dimensional Analysis
- 6 oz = ? ml
6 oz x 2 Tbsp x 15 ml = 180 = 180 ml
? 1 oz 1 Tbsp 1
- 4,000 mcg = ? mg
4,000 mcg x 1 mg = 4,000 = 4 mg
? 1,000 mcg 1,000
- 5 G = ? mcg
5 G x 1,000 mg x 1,000 mcg = 5,000,000 = 5,000,000 mcg
? 1 G 1 mg 1
- 50 ml = ? oz
50 ml x 1 Tbsp x 1 oz = 50 = 1.6666 = 1.7 oz
? 15 ml 2 Tbsp 30
- 96 kg = ? lbs
96 kg x 2.2 lbs = 211.2 211.2 lbs
? 1 kg 1
- 20 tsp = ? ml
20 tsp x 5 ml = 100 = 100 ml
