Actual Exam Coverage: BSN HESI 215 Dosage Calculations
The HESI Dosage exam focuses on the safe calculation and
administration of medications, including all aspects of
measurement, conversions, and clinical decision-making.
The coverage typically includes:
1. Basic Math Skills
o Fractions, decimals, percentages
o Ratios and proportions
o Unit conversions (metric, apothecary, household)
2. Dosage Calculations
o Tablets, capsules, liquid medications
o Pediatric dosing based on weight
o Body surface area (BSA) calculations
o IV flow rate calculations (mL/hr, gtt/min)
,3. Medication Administration
o Routes of administration (oral, subcutaneous,
intramuscular, IV)
o Safe injection practices
o Reconstitution of powdered medications
o Calculating safe dosage ranges
4. Conversions
o Metric system (mg ↔ g, mL ↔ L)
o Apothecary system (grains, drams, ounces)
o Household units (tsp, tbsp, cups)
5. Problem-Solving Skills
o Multi-step dosage problems
o Rounding rules per nursing standards
o Identifying errors in prescriptions
6. Clinical Scenarios
o Patient-specific variables (age, weight, renal
function)
o Medication errors prevention
o Critical thinking in urgent situations
,1.
A 6-year-old child weighing 22 kg requires amoxicillin 50
mg/kg/day divided into three doses. How many mg per
dose should be administered?
A) 366 mg
B) 350 mg
C) 375 mg
D) 400 mg
Answer: A) 366 mg
Rationale: Total daily dose = 50 mg × 22 kg = 1,100
mg. Divided by 3 doses = 366.6 ≈ 366 mg per dose.
2.
A provider orders 0.25 mg digoxin daily. You have 0.125
mg tablets available. How many tablets should you
administer?
A) 1 tablet
B) 2 tablets
C) 0.5 tablet
D) 3 tablets
Answer: B) 2 tablets
, Rationale: 0.125 mg × 2 = 0.25 mg. Two tablets meet
the ordered dose.
3.
A patient requires 1,000 mL IV NS to infuse over eight
hours. Calculate the flow rate in mL/hr.
A) 125 mL/hr
B) 150 mL/hr
C) 100 mL/hr
D) 110 mL/hr
Answer: A) 125 mL/hr
Rationale: Flow rate = total volume ÷ time = 1,000 ÷
8 = 125 mL/hr.
4.
The prescription reads: Ceftriaxone 50 mg/kg IV once
daily. Patient weighs 18 kg. The vial contains 250 mg/mL.
How many mL should be administered?
A) 3.6 mL
B) 4 mL
C) 3 mL
