A nurse is preparing to administer amoxicillin 320 mg PO every 12 hr to an infant. The amount available is amoxicillin suspension 400 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["4"]
To determine the correct dosage, the nurse should use the formula: (desired dose / amount on hand) x volume = amount to administer. In this case, it would be (320 mg / 400 mg) x 5 mL. This simplifies to 0.8 x 5 mL, which equals 4 mL.
