BIOD351 Module 10 Dosing Calculations
Comprehensive Final Test (Qns & Ans)
2025
Question 1 (Multiple Choice)
Question:
A patient is prescribed 250 µg of medication Z to be given
intravenously. The available vial contains 10 mg of drug in
10 mL. Using dimensional analysis, what volume (in mL) is
required to administer the prescribed dose?
A) 0.025 mL
B) 0.25 mL
C) 2.5 mL
D) 25 mL
Correct ANS:
©2025
,B) 0.25 mL
Rationale:
Convert 250 µg to milligrams: 250 µg = 0.25 mg. The vial’s
concentration is 10 mg/10 mL = 1 mg/mL. Therefore, 0.25 mg
requires 0.25 mg ÷ 1 mg/mL = 0.25 mL.

Question 2 (Fill in the Blank)
Question:
A pediatric patient weighing 15 kg is prescribed a drug at a dose
of 5 mg/kg. The total dose in milligrams is ________ .
Correct ANS:
75 mg
Rationale:
Multiply the weight by the dose per kilogram: 15 kg × 5 mg/kg =
75 mg.

, Question 3 (True/False)
Question:
True/False: When calculating pediatric dosing, rounding a
patient’s weight to the nearest kilogram before performing the
calculation may introduce significant dosing errors.
Correct ANS:
True
Rationale:
Precise dosing is critical in pediatric populations. Rounding the
weight prematurely can lead to substantial errors in the calculated
dose, potentially compromising safety and efficacy.

Question 4 (Multiple Response)
Question:
Select all methods that help ensure dimensional consistency in
dosing calculations:
A) Setting up conversion factors as fractions
