Erythromycin 1000 mg divided into two equal doses daily is prescribed intravenously for a client with a severe case of cellulitis. Each dose is to be administered over 30 minutes. The pharmacy sends erythromycin 500 mg/100 ml. At what rate should the nurse administer the medication? Round to the whole number

Calculation: Determine the dose per administration Total Daily Dose: 1000 mg Divided into 2 doses → 1000 ÷ 2 = 500 mg per dose Identify the available concentration 500 mg in 100 mL: each dose = 100 mL Identify the infusion time Time: 30 minutes = 0.5 hours Calculate the infusion rate Flow Rate (mL/hr) = Volume ÷ Time Flow Rate = 100 ÷ 0.5 = 200 mL/hr
