Domain 1: Basic Dosage Calculation Methods
Q1. A physician orders 0.5 g of a medication. The available supply is 250 mg tablets. Using the
formula method (D/H x Q), how many tablets should the nurse administer?
A. 1 tablet
B. 2 tablets
C. 0.5 tablet
D. 4 tablets
Rationale: Convert 0.5 g to 500 mg. D/H x Q = 500 mg / 250 mg x 1 tablet = 2 tablets. Always
ensure units match before calculating.
Q2. Using ratio and proportion, a nurse needs to administer 75 mg of a medication available as 50
mg/2 mL. Set up the proportion correctly and solve for the volume to administer.
A. 2.5 mL
B. 3.0 mL
C. 3.5 mL
D. 1.5 mL
Rationale: 50 mg : 2 mL = 75 mg : X mL. Cross-multiply: 50X = 150. X = 150/50 = 3 mL. Ratio
and proportion yields the same result as the formula method.
Q3. A nurse uses dimensional analysis to convert 1,500 mg to grams. What is the correct
conversion?
A. 15 g
B. 0.15 g
C. 1.5 g
D. 150 g
Rationale: 1,500 mg x (1 g / 1,000 mg) = 1.5 g. Dimensional analysis cancels the mg units,
leaving the answer in grams. Moving the decimal 3 places to the left.
Q4. Order: Amoxicillin 500 mg PO. Available: Amoxicillin 250 mg/5 mL oral suspension. How
many mL should the nurse administer?
A. 5 mL
