BSN 215 HESI Dosage Calculation Exam V1 Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This collection presents one hundred (100) original, university-level questions developed for the BSN 215
HESI Dosage Calculation Exam V1 Comprehensive Examination at Nightingale College. The material is
organized into four core domains: Basic Math and Proportions for Dosage Calculation; Oral and Enteral
Medication Calculations; Parenteral and Intravenous (IV) Medication Calculations; and Pediatric and
Weight-Based Dosage Calculations. Every item is written to reinforce the official BSN 215 Comprehensive
Examination course objectives, supporting actual exam readiness and the development of clinical proficiency
in converting between measurement systems, applying ratio and proportion, computing oral, parenteral, and
infusion doses, and checking weight based pediatric orders against safe dose ranges. All content is aligned to
the 2026/2027 academic year and reflects current evidence-based clinical care and medication
administration standards.
ACTUAL QUESTIONS
Domain 1: Basic Math and Proportions for Dosage Calculation
Question 1. Express 1,240 as a Roman numeral.
A. MCXL
B. MCDXL
C. MCCX
D. MCCXL
Correct Answer: D
Rationale: Nightingale College BSN 215 course materials begin with the Roman numeral system still used
on some prescription labels. M = 1,000, CC = 200, and XL = 40 (ten before fifty means subtract), so MCCXL
= 1,240.
Question 2. A prescription label is written with the Roman numeral XLIV. What is the
equivalent Arabic number?
A. 64
B. 44
C. 54
D. 46
Correct Answer: B
Rationale: XL = 40 and IV = 4, so XLIV = 44. Per Kee, a smaller numeral placed before a larger one is
subtracted, and one placed after is added.
Question 3. Subtract 1/3 from 3/4 and express the answer as a single fraction.
A. 2/1
B. 2/12
C. 7/12
D. 5/12
Correct Answer: D
Rationale: Per Kee and the calculation method used in the BSN 215 course materials, the lowest common
denominator is 12, so 3/4 becomes 9/12 and 1/3 becomes 4/12. Subtracting gives 9/12 minus 4/12 = 5/12,
and the fraction cannot be reduced further.
Question 4. Divide 1/2 by 1/4.
A. 1/8
B. 1/2
C. 2
D. 8
Correct Answer: C

, Rationale: Nightingale College BSN 215 course materials and Potter and Perry emphasize that to divide
fractions, invert the second fraction and multiply: 1/2 x 4/1 = 4/2 = 2. This skill is used when determining
how many fractional tablet portions a dose requires.
Question 5. Multiply 0.375 by 2.4.
A. 0.09
B. 9
C. 0.009
D. 0.9
Correct Answer: D
Rationale: Nightingale College BSN 215 course materials and Kee indicate that multiply as whole numbers
(375 x 24 = 9,000) and then place the decimal point four places from the right, because there are three
decimal places in 0.375 and one in 2.4, giving 0.9.
Question 6. Convert 0.9 percent to a decimal.
A. 0.009
B. 0.9
C. 0.09
D. 9.0
Correct Answer: A
Rationale: Per Nightingale College BSN 215 course materials and standard calculation method, percent
means per hundred, so 0.9 percent is 0.9 divided by 100 = 0.009. This conversion is used to read solution
strengths such as 0.9 percent sodium chloride, which contains 0.9 g in every 100 mL.
Question 7. Convert 0.125 to a percent.
A. 1.25 percent
B. 0.125 percent
C. 12.5 percent
D. 125 percent
Correct Answer: C
Rationale: To change a decimal to a percent, multiply by 100 and move the decimal point two places right,
so 0.125 becomes 12.5 percent. Kee emphasizes moving the decimal two places in the correct direction to
avoid a tenfold dose error.
Question 8. A topical liquid is labeled 2 percent. How many milligrams of drug are in each
milliliter?
A. 2 mg per mL
B. 200 mg per mL
C. 0.2 mg per mL
D. 20 mg per mL
Correct Answer: D
Rationale: Nightingale College BSN 215 course materials and Potter and Perry emphasize that a 2 percent
strength means 2 g in 100 mL. Converting grams to milligrams gives 2,000 mg in 100 mL, and 2,000
divided by 100 = 20 mg per mL.
Question 9. How many grams of sodium chloride are in a 500 mL bag of 0.9 percent sodium
chloride?
A. 0.45 g
B. 4.5 g
C. 45 g
D. 9 g
Correct Answer: B
