Volume in liters = 30 ÷ 1000
= 0.03 L
Correct Answer is B
Explanation
Identify the ordered dose and available concentration
Ordered Dose: 1 g (1000 mg)
Available Concentration: 500 mg/2 mL
Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (1000 ÷ 500) × 2
Volume to administer = 2 × 2
= 4 mL
