The Correct Answer is ["1.5"]
Given:
Desired dose of iron dextran: 75 mg
Concentration of iron dextran injection: 50 mg/mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
75 mg / Volume = 50 mg/mL
Step 3: Solve for the unknown volume:
Volume = 75 mg / 50 mg/mL

Correct Answer is ["120"]
Explanation
Given:
Desired dose of ferrous sulfate: 0.12 g
Conversion factor: 1 g = 1,000 mg
Step 1: Convert grams to milligrams:
Desired dose in mg = Desired dose in g x Conversion factor (mg/g)
Desired dose in mg = 0.12 g x 1,000 mg/g
Desired dose in mg = 120 mg
Correct Answer is ["6.7"]
Explanation
Given:
Desired dose of ferrous sulfate: 120 mg
Concentration of ferrous sulfate syrup: 90 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
120 mg / Volume = 90 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 120 mg / (90 mg/5 mL)
Step 4: Calculate the volume:
Volume = 120 mg / 18 mg/mL
Volume = 6.666666667 mL
Step 5: Round to the nearest tenth:
Volume ≈ 6.7 mL
