If Mrs. Smith's dry weight is 62 kg and her pretreatment weight is 67 kg, what is the total fluid weight to be removed during her treatment?

To determine the total fluid weight that needs to be removed during Mrs. Smith's treatment, you first need to understand the concept of dry weight versus pretreatment weight. Dry weight refers to the target weight of a patient after excess fluids have been removed, while the pretreatment weight is the weight before the removal of excess fluids.

In this case, Mrs. Smith's dry weight is 62 kg, and her pretreatment weight is 67 kg. The excess fluid weight that needs to be removed can be calculated by subtracting her dry weight from her pretreatment weight:

67 kg (pretreatment weight) - 62 kg (dry weight) = 5 kg

Since 1 kg of weight corresponds to 1,000 mL of fluid, the total volume of fluid to be removed is:

5 kg x 1,000 mL/kg = 5,000 mL

The answer of 5,540 mL may stem from additional considerations, such as a weight accumulation that accounts for a maintenance or ultrafiltration goal, but based purely on the numbers provided (without further context or additional information on the option of 5,540 mL), it demonstrates the straightforward calculation to identify the necessary fluid removal aligned with Mrs.
