CALCULATION OF DRUG DOSAGES
PREPARATION TEST 2026 QUESTIONS AND
CORRECT ANSWERS GRADED A+

● Drops as units of volume


Standard: _____ drops (gtts) = 1 mL. Answer: 16 drops (gtts) = 1 mL


● Household Units of Measure:


1 teaspoon = ____ mL = ____ drops


1 tablespoon = ____ mL ( ____ teaspoons)


1 cup = ____ mL (____ fluid ounces). Answer: 1 teaspoon = 5 mL * =
60 drops


1 tablespoon = 15 mL (3 teaspoons)


1 cup = 240 mL (8 fluid ounces)

,● Calculating Doses from Prepared-Strength Liquids, Tablets, and
Capsules:


Calculating with Proportions & Drug Amounts in Units. Answer: • When
using prepared strength liquid, or solid, you determine how much of the
medication dispense is required to give the amount or dose of the drug
ordered


Steps:


1.) Convert to consistent units of measure


2.) Set up straightforward proportion:


Original Dose/Per Amount = Desired Dose/Per Amount


● Calculating Doses from Prepared-Strength Liquids, Tablets, and
Capsules:


Calculations with Dosage Schedule. Answer: • Calculate dose needed


• Calculate the amount of the preparation

, Original Dose/ Per Amount = Desired Dose/Per Amount




*Schedule: Amount of drug needed, based on pt's weight


● Calculating Doses from Percentage-Strength Solutions:


Types of percentage preparations. Answer: • weight to weight w/w = g/g
= g/100g


• weight to volume w/v = g/mL = g/100 mL


• volume to volume v/v = mL/mL = mL/100 mL


● Ratio by Gram (g) to Milliliters (mL). Answer: 1:100
1g/100ml = 0.01 x 100 = 1%


Ex: 1:200
1g per 200 mL of solution = 1g/200 mL = 0.005 x 100 = 0.5%


● Solving Percentage-Strength Solution Problems (Equation 1).
Answer: % Strength = Solute/Total Amount
