Introduction:
This comprehensive ATI Dosage Calculation examination is designed to assess
the mathematical competency and clinical reasoning skills essential for safe
medication administration in adult medical-surgical nursing. The assessment
covers a broad spectrum of dosage calculation topics including basic
conversions, oral and parenteral dosing, IV flow rate calculations, weight-
based dosing, and safe dose range verification. Candidates will encounter
multiple-choice questions that require application of theoretical knowledge to
real-world clinical scenarios. Emphasis is placed on accuracy, safety, and
evidence-based practice. Successful completion of this examination
demonstrates readiness to perform precise medication calculations and
administer medications safely across diverse healthcare settings.
SECTION ONE: QUESTIONS 1-100
,1. A nurse is preparing to administer 500 mg of a medication. The available
dose is 250 mg per tablet. How many tablets should the nurse administer?
A. 1 tablet
B. 1.5 tablets
C. 2 tablets
D. 2.5 tablets
C. 2 tablets
RATIONALE: To calculate the number of tablets, divide the desired dose by
the available dose per tablet: 500 mg ÷ 250 mg/tablet = 2 tablets. Always verify the
calculation by checking that the units cancel correctly.
2. A patient is prescribed 1,000 mL of 0.9% normal saline to infuse over 8
hours. The drop factor is 15 gtt/mL. What is the flow rate in drops per
minute?
A. 31 gtt/min
B. 35 gtt/min
C. 42 gtt/min
D. 50 gtt/min
A. 31 gtt/min
RATIONALE: Use the formula: (Volume × Drop factor) ÷ Time (minutes).
1,000 mL × 15 gtt/mL = 15,000 gtt. Time = 8 hours × 60 minutes = 480 minutes.
15,000 ÷ 480 = 31.25 gtt/min, rounded to 31 gtt/min.
3. A nurse is to administer heparin 5,000 units subcutaneously. The medication
is available in a vial labeled 10,000 units/mL. How many mL should the nurse
administer?
A. 0.25 mL
B. 0.5 mL
,C. 1 mL
D. 2 mL
B. 0.5 mL
RATIONALE: Use the formula: Desired dose ÷ Available dose × Quantity.
5,000 units ÷ 10,000 units/mL = 0.5 mL. Always double-check the concentration
and desired dose before administration.
4. A patient is to receive 60 mg of furosemide IV push. The medication is
available as 10 mg/mL. How many mL should the nurse administer?
A. 2 mL
B. 4 mL
C. 6 mL
D. 8 mL
C. 6 mL
RATIONALE: 60 mg ÷ 10 mg/mL = 6 mL. When administering IV push, the
nurse should also check the recommended rate of administration for the specific
medication.
5. A patient is ordered to receive cefazolin 1 g IV every 8 hours. The pharmacy
provides a vial containing 500 mg/mL. How many mL should the nurse
administer for each dose?
A. 1 mL
B. 2 mL
C. 3 mL
D. 4 mL
B. 2 mL
, RATIONALE: Convert 1 g to mg: 1 g = 1,000 mg. 1,000 mg ÷ 500 mg/mL = 2
mL. Always ensure proper reconstitution and check for stability before
administration.
6. A nurse is calculating the safe dose range for a pediatric patient. The
recommended dose is 25-50 mg/kg/day divided into 4 doses. The child weighs
20 kg. What is the maximum dose per day?
A. 500 mg/day
B. 750 mg/day
C. 1,000 mg/day
D. 1,250 mg/day
C. 1,000 mg/day
RATIONALE: Maximum dose = 50 mg/kg/day × 20 kg = 1,000 mg/day. The
minimum dose = 25 mg/kg/day × 20 kg = 500 mg/day. Always verify the
prescribed dose falls within the safe range.
7. A patient is prescribed 2,500 mL of total parenteral nutrition (TPN) to
infuse over 24 hours. The IV administration set delivers 20 gtt/mL. What is
the flow rate in drops per minute?
A. 17 gtt/min
B. 25 gtt/min
C. 35 gtt/min
D. 42 gtt/min
C. 35 gtt/min
RATIONALE: 2,500 mL × 20 gtt/mL = 50,000 gtt. 50,000 gtt ÷ (24 hours × 60
minutes) = 34.72 gtt/min, rounded to 35 gtt/min.
