The heath care provider prescribes ampicillin 50mg/kg every 8 hours to your neonate weighing 4226 g. Ampicillin is dispensed in a 500mg vial. You need to reconstitute the ampicillin with 5mL of sterile water to yield a concentration of 100mg/mL. How many mL(s) of ampicillin will you give to your client. Round to the nearest tenth.
The Correct Answer is ["2.1"]
Step 1: Calculate the desired dose.
50 mg/kg x 4.226 kg = 211.3 mg
Step 2: Calculate the volume to administer.
211.3 mg / 100 mg/mL = 2.1 mL
Therefore, you will administer 2.1 mL of ampicillin.
