Introduction
,The ATI Dosage Calculation PN Adult Medical Surgical
Proctored Assessment 3.2 evaluates the practical nursing
student's competency in accurate medication dosage
computation and safe administration across adult medical-
surgical clinical scenarios. This comprehensive assessment
covers foundational unit conversions, oral and parenteral
medication calculations, intravenous flow rates, medication
reconstitution, and high-alert medication safety. The test
utilizes multiple-choice and calculation-based questions that
mirror the rigor of the actual ATI proctored assessment.
Emphasis is placed on step-by-step calculation accuracy,
proper rounding rules, and clinical judgment essential for safe
nursing practice.
SECTION ONE: QUESTIONS 1–100
1. A nurse is preparing to administer phenytoin 0.2 g PO.
Available is phenytoin 100 mg capsules. How many
capsules should the nurse administer?
A. 1 capsule
B. 2 capsules
C. 3 capsules
D. 4 capsules
,🟢 B. 2 capsules
🔴 RATIONALE: First, convert grams to milligrams: 0.2 g ×
1,000 = 200 mg. Then, divide the desired dose by the
available dose: 200 mg ÷ 100 mg = 2 capsules .
2. A nurse is preparing to administer amoxicillin 250 mg
PO. Available is amoxicillin 125 mg/5 mL. How many mL
should the nurse administer?
A. 5 mL
B. 10 mL
C. 15 mL
D. 20 mL
🟢 B. 10 mL
🔴 RATIONALE: Use the formula (Desired ÷ Have) × Volume.
(250 mg ÷ 125 mg) × 5 mL = 2 × 5 mL = 10 mL .
3. A nurse is preparing to administer 0.9% sodium chloride
1,000 mL IV to infuse over 8 hr. The nurse should set the IV
pump to deliver how many mL/hr?
A. 80 mL/hr
B. 100 mL/hr
C. 125 mL/hr
D. 150 mL/hr
, 🟢 C. 125 mL/hr
🔴 RATIONALE: Divide the total volume by the total time in
hours: 1,000 mL ÷ 8 hr = 125 mL/hr .
4. A provider prescribes heparin 5,000 units SC every 12 hr.
Available is heparin injection 10,000 units/mL. How many
mL should the nurse administer per dose?
A. 0.25 mL
B. 0.5 mL
C. 1 mL
D. 2 mL
🟢 B. 0.5 mL
🔴 RATIONALE: (5,000 units ÷ 10,000 units) × 1 mL = 0.5 mL
.
5. A nurse is preparing to administer cefazolin 1 g IM. The
nurse reconstitutes a 1 g vial with 2.5 mL of sterile water to
yield a concentration of 330 mg/mL. How many mL should
the nurse administer?
A. 0.3 mL
B. 2.5 mL
C. 3.0 mL
D. 3.3 mL
