Calculation Conventions
Use 1 kg = 2.2 lb, 1 g = 1,000 mg, 1 mg = 1,000 mcg, and 1 L = 1,000
mL. Do not round until the final calculation. Round gravity-flow rates to the
nearest whole gtt/min. Round pump rates and medication volumes as
directed. Use a leading zero for answers less than 1 and avoid unnecessary
trailing zeros.

Q1. A patient weighs 187 lb. What is the patient's weight in
kilograms?
A) 80 kg
B) 85 kg
C) 90 kg
D) 93.5 kg
Correct Answer: B) 85 kg
Rationale: 187 lb ÷ 2.2 lb/kg = 85 kg.
Q2. Convert 1.375 g to milligrams.
A) 137.5 mg
B) 13,750 mg
C) 1,375 mg
D) 0.1375 mg
Correct Answer: C) 1,375 mg
Rationale: 1.375 g × 1,000 mg/g = 1,375 mg.
Q3. Convert 750 mcg to milligrams.
, A) 0.75 mg
B) 7.5 mg
C) 75 mg
D) 0.075 mg
Correct Answer: A) 0.75 mg
Rationale: 750 mcg ÷ 1,000 mcg/mg = 0.75 mg.
Q4. An IV solution contains 2.25 L. How many milliliters are present?
A) 225 mL
B) 1,250 mL
C) 2,025 mL
D) 2,250 mL
Correct Answer: D) 2,250 mL
Rationale: 2.25 L × 1,000 mL/L = 2,250 mL.
Q5. Dexamethasone 6 mg IV is prescribed. The vial contains 10
mg/mL. How many milliliters should the nurse administer?
A) 0.3 mL
B) 1.6 mL
C) 0.6 mL
D) 6 mL
Correct Answer: C) 0.6 mL
Rationale: 6 mg ÷ 10 mg/mL = 0.6 mL.
Q6. Methylprednisolone 125 mg IV is ordered. The medication
contains 62.5 mg/mL. How many milliliters should be administered?
A) 1 mL
B) 2 mL
C) 2.5 mL
D) 4 mL
Correct Answer: B) 2 mL
Rationale: 125 mg ÷ 62.5 mg/mL = 2 mL.
Q7. Ceftriaxone 1.5 g is prescribed. After reconstitution, the
concentration is 350 mg/mL. How many milliliters should be
administered? Round to the nearest tenth.
