Mr. Worley is in the critical care unit of the hospital and is on a fluid restriction. Today he has consumed 250 mL of clear broth and 200 mL of water. He weighs 142 lb. To achieve his DMFN, the hourly flow rate on his IV should be ________. (A volume control chamber is not being used on his IV.)
Fill in the blank(s) with the appropriate word(s).
81 mL/h
Convert the weight to kilograms:
He weighs more than 20 kg, so using the proper formula:
DMFN = 2,390 mL
Total the fluids taken by mouth and subtract them from the fluid needed:
250 mL + 200 mL = 450 mL by mouth
2,390 mL - 450 mL = 1,940 mL
Calculate the flow rate:
V = 1,940 mL; T = 24 hours
F = 80.83, rounded to 81 mL/h
