The nurse would document the total intake for a 12-hour shift as 1,817 mL given the following: three eight-ounce cups of water, 0.9% sodium chloride at 70 mL/hr, 500 mg azithromycin in 250 mL 0.9% sodium chloride, and 5 mg morphine sulfate diluted to 7 mL. What is the total intake in mL?

• A. 1817 mL
• B. 1815 mL
• C. 1810 mL
• D. 1800 mL

Answer: (A)

Total intake is the sum of every fluid volume administered, all converted to milliliters. First convert the water: three eight-ounce cups equal 24 ounces. Using 1 ounce as 30 mL, 24 oz × 30 mL/oz = 720 mL. Add the IV saline: 70 mL per hour for 12 hours equals 70 × 12 = 840 mL. Add the antibiotic solution: the volume given is 250 mL. Add the morphine solution: the diluted volume is 7 mL. Now sum: 720 + 840 + 250 + 7 = 1,817 mL. So the total intake documented is 1,817 mL. The drug concentrations affect dosing, but for intake total you add the volumes of all fluids administered.

Add the morphine solution: the diluted volume is 7 mL.

Now sum: 720 + 840 + 250 + 7 = 1,817 mL.

So the total intake documented is 1,817 mL. The drug concentrations affect dosing, but for intake total you add the volumes of all fluids administered.
