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 285.5 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? (Enter number value only. If rounding is required, round to the nearest whole number.)

Since the client weighs 90 kg, let’s first convert their weight to pounds to determine the appropriate cefazolin dosage: Conversion factor: 1 kg = 2.205 pounds Client weight (pounds) = 90 kg x 2.205 pounds/kg = 198.45 pounds (rounded to two decimals) Now, comparing the client’s weight (198.45 pounds) to the weight threshold (265.5 pounds): Client weight is less than the threshold (198.45 pounds < 265.5 pounds). Therefore, the appropriate dosage is: Cefazolin 2 grams/100 mL 0.9% normal saline over 1 hour. The pump rate is determined by the total volume of the IV fluid and the infusion time. We are not given the specific bag size, but typically these come in 100 mL or 500 mL volumes. Assuming a 100 mL bag (which aligns with the concentration provided): Total volume of IV bag: 100 mL Infusion time: 1 hour Calculation: Pump rate (mL/hr) = Total volume (mL) / Infusion time (hr) Pump rate (mL/hr) = 100 mL / 1 hour = 100 mL/hr Therefore, the nurse should program the pump to deliver 100 mL/hr.
