A nurse is preparing to administer amoxicillin 500 mg PO to a client. Available is amoxicillin oral suspension 250 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the dose of amoxicillin oral suspension for a client, the nurse needs to use the following formula: Dose (mL) = Desired dose (mg) / Available dose (mg/mL) x Volume (mL). In this case, the desired dose is 500 mg, the available dose is 250 mg/5 mL, and the volume is 5 mL. Therefore, the dose (mL) = 500 mg / (250 mg/5 mL) x 5 mL = 10 mL. The nurse should administer 10 mL of amoxicillin oral suspension to the client.
