The healthcare provider prescribes the antibiotic surgical prophylaxis protocol for a client who weighs 90 kg. The protocol is cefazolin 2 grams/100 mL 0.9% normal saline over 1 hour for clients weighing less than 265.5 pounds or cefazolin 3 grams/100 mL 0.9% normal saline over 90 minutes for clients weighing greater than 265.5 pounds. The nurse should program the pump to deliver how many mL/hr?

First, convert the client's weight from kilograms to pounds: 1 kg = 2.2 lbs Step 1: 90 kg × 2.2 lbs/kg = 198 lbs Since the client weighs less than 265.5 pounds, the protocol specifies cefazolin 2 grams/100 mL over 1 hour. Determine the flow rate in mL/hr: The total volume to be infused is 100 mL. The infusion time is 1 hour. Step 2: 100 mL ÷ 1 hour = 100 mL/hr Therefore, the nurse should program the pump to deliver 100 mL/hr.
