Calculation
A nurse is calculating fluid input for a client who is receiving a continuous IV infusion of 0.9% sodium chloride at 125 mL/hr and cefazolin 50 mL IV bolus every 4 hr. How many mL did the client receive per IV infusion over the past 24 hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculate the total fluid from the continuous IV infusion Continuous IV: 125 mL/hr × 24 hr = 3,000 mL Calculate the total fluid from the cefazolin IV boluses Cefazolin IV: 50 mL every 4 hr → 24 ÷ 4 = 6 doses Total from boluses: 50 × 6 = 300 mL Calculate the total IV fluid in 24 hours Total IV fluid = 3,000 + 300 = 3,300 mL
