A client is receiving dextrose 5% in water IV at 150 mL/hr and has ingested 4 oz of water and 1/2 pint of milk. What is the total 8-hour fluid intake in milliliters?

A client is receiving dextrose 5% in water IV at 150 mL/hr and has ingested 4 oz of water and 1/2 pint of milk. What is the total 8-hour fluid intake in milliliters?

• A. 1400
• B. 1560
• C. 1680
• D. 1800

Answer: (B)

Compute total fluid intake by adding the IV fluid over the 8 hours to the oral intake converted to milliliters. The IV rate is 150 mL per hour for 8 hours, which equals 150 × 8 = 1200 mL. For the oral intake, convert to milliliters: 4 oz of water is 4 × 30 = 120 mL, and half a pint is 8 oz (since a pint is 16 oz), which is 8 × 30 = 240 mL. So the total oral intake is 120 + 240 = 360 mL. Add the IV and oral amounts: 1200 + 360 = 1560 mL. Using a more exact conversion (29.57 mL per oz) would give about 1555 mL, still closest to 1560.
