Weight gain or loss gives the nurse information regarding change in body fluids. The nurse should be aware that 1 liter of fluid weighs:
2.2 kg
1.0 kg
0.5 kg
0.22 kg
The Correct Answer is B
A. 2.2 kg: 2.2 kg is equivalent to approximately 5 lbs and overestimates the weight of 1 L of fluid.
B. 1.0 kg: 1 liter of fluid = 1 kilogram (kg). This is used to track fluid gain/loss accurately.
C. 0.5 kg: 0.5 kg would be equivalent to 500 mL, not 1 L.
D. 0.22 kg: 0.22 kg is far below the actual weight of 1 L of fluid.
