Alignment & How to Use This Workbook
The 2026 Galen College of Nursing student catalog continues to list NUR 168 as an 8-quarter-credit course
supporting the transition from practical/vocational nursing to registered nursing practice, with classroom,
laboratory, and clinical learning. A publicly available NUR 168 syllabus blueprint specifies a 10-question
dosage calculation test and a minimum score of 90% within the allowed attempts. This workbook is
organized to mirror the calculation domains disclosed in that blueprint while keeping all practice items
original.
Blueprint Domain Publicly listed item count Workbook coverage
Conversions & rounding 2 Core Section A + drills
Reading medication labels 2 Core Section B + label simulations
Dimensional analysis:
2 Core Section C + drills
tablets/capsules
Dimensional analysis: mL 2 Core Section D + drills
Body-weight safe-dose range 1 Bonus full-blueprint section
Calculations related to time: mg/day 1 Bonus full-blueprint section
Important accuracy note
The detailed dosage blueprint used for organization is from a publicly available NUR 168 syllabus rather than an
official September 2026 exam release. Galen can revise course packets, rounding rules, test wording, and schedules.
Use the current Canvas/course packet as the final authority.
A 90% Readiness Strategy
Learn one setup method and use it consistently. This workbook emphasizes dimensional analysis
because it makes units cancel visibly.
Write the unit beside every number. A correct number with the wrong unit is unsafe.
Do not round during intermediate steps unless instructed. Carry the calculator value, then round the
final answer.
Use a leading zero for values less than 1 (0.5 mL), and do not use trailing zeros (write 5 mg, not 5.0 mg).
Treat every label as a data source: identify the concentration, dosage form, and quantity represented
before calculating.
Score each readiness test. A target of at least 9/10 matches the 90% threshold disclosed in the public
syllabus.

Quick Reference: Units, Safety Notation & Core Formula
Metric Relationships
Relationship Meaning Example
1 kg = 1,000 g kg -> g: multiply by 1,000 0.8 kg = 800 g
1 g = 1,000 mg g -> mg: multiply by 1,000 0.25 g = 250 mg
1 mg = 1,000 mcg mg -> mcg: multiply by 1,000 0.4 mg = 400 mcg
1 L = 1,000 mL L -> mL: multiply by 1,000 0.75 L = 750 mL
2.2 lb ≈ 1 kg lb -> kg: divide by 2.2 154 lb ÷ 2.2 = 70 kg
Safety Notation
Use a leading zero: 0.25 mg, not .25 mg.
Avoid a trailing zero: 2 mg, not 2.0 mg.
Keep units attached throughout the calculation so unwanted units cancel.
If a question provides a specific rounding instruction, that instruction controls the final answer.
Core dimensional-analysis setup
Amount ordered × conversion factor(s) × quantity supplied / amount on hand = amount to administer. Arrange
factors so unwanted units cancel and only the requested final unit remains.
SECTION A - Conversions & Rounding
1. Conversion Method
Start with the value you have. Multiply by a conversion factor written so the starting unit cancels. The
remaining unit is the answer unit. When moving from a larger metric unit to a smaller unit, the numeric
value becomes larger; when moving from smaller to larger, it becomes smaller.
1. 0.65 g to mg
Answer: 0.65 g × (1,000 mg / 1 g) = 650 mg
The g units cancel, leaving mg.
2. 1,250 mcg to mg
Answer: 1,250 mcg × (1 mg / 1,000 mcg) = 1.25 mg
The mcg units cancel, leaving mg.
3. 0.9 L to mL
Answer: 0.9 L × (1,000 mL / 1 L) = 900 mL
The L units cancel, leaving mL.
