The healthcare provider has ordered 500 mg of ampicillin. The vial is a 1 g vial, and after reconstitution, the label reads 1 g/5 mL. How many mL will you administer?
Do not provide the unit of measurement. Only provide the number. Round to one decimal place (tenths).
The Correct Answer is ["2.5"]
Step 1: Available concentration = 1 g/5 mL = 1000 mg/5 mL = 200 mg/mL
Step 2: Ordered dose = 500 mg
Step 3: Volume to administer = 500 ÷ 200 = 2.5
Final Answer: 2.5
