The physician orders Amoxil 500mg PO BID. The Amoxil is, supplied 250mg/10mL. How many mL will the nurse administer?
The Correct Answer is ["20"]
Rationale:
To calculate the volume to administer, use the formula:
(Desired dose ÷ Dose on hand) × Volume on hand = Volume to administer
(500 mg ÷ 250 mg) × 10 mL = 2 × 10 mL = 20 mL
The nurse will administer 20 mL per dose.
