- metric system
- household system
Weight is a basic unit that refers to a drugs -
heaviness
BSA -
Area of external surface of the body, expressed in square meters, used to calculate
metabolic, electrolyte, and nutritional requirements
Formula method -
basic formula to calculate dosage
Nomogram -
a form of line chart showing scales for the variables involved in a particular formula
in such a way that corresponding values for each variable lie in a straight line intersecting all
the scales
Proportion Method -
a fraction formula based on ratios and proportions that is used to calculate dosage
A medical assistant must perform all dosage calculations carefully and accurately to prevent -
medication errors

, Which of the following metric systems is most commonly used for pharmacology and drug
administration in the United States ? -
metric
Volume is the amount of space a -
drug occupies
When working with decimals it is important to -
- write the whole number of the decimal to the left of the decimal point
- write the decimal fraction part to the right of the decimal point
________ refers to the amount of space a drug occupies. -
Volume
In order to execute all dosage calculations carefully and accurately, a medical assistant must -
- perform basic math
- know calculations for special populations
- understand various systems of measurement
Which of the following system is based on multiples of 10? -
metric system
When covering units of measure, what is the most common system used for dosage
calculations? -
metric system
The accepted medical abbreviation of the equivalent of one cubic centimeter is 1 -
mL
When rounding decimals it is important to -
- underline the place value to which you want to round
- drop all digits to the right of the target place value
- always write a zero to the left go the decimal point when the decimal number has no whole
number part
Converting one metric unit of measurement to another is similar to multiplying and dividing -
decimal numbers
when performing dosage calculations, it might be necessary to convert units from one system
to another. In order to do this -
- you can calculate the dose using a proportion method
- you can use a conversion chart that provides equivalent measurements
the basic units of volume and weight win the decimal based metric system are liters to
measure volume and grams to measure -
