What fluid removal target should a nurse set if a patient has a preweight of 70.5 kg and an estimated dry weight of 68 kg?

To determine the appropriate fluid removal target based on the patient's preweight and estimated dry weight, the nurse needs to calculate the fluid volume to be removed during dialysis. The preweight of the patient is 70.5 kg, while the estimated dry weight is 68 kg. The difference between these two weights represents the excess fluid that needs to be removed.

Calculating the excess fluid involves subtracting the estimated dry weight from the preweight:

70.5 kg (preweight) - 68 kg (dry weight) = 2.5 kg

Since 1 kg of weight loss is equivalent to approximately 1,000 mL of fluid, the total fluid removal target can be calculated in milliliters:

2.5 kg x 1,000 mL/kg = 2,500 mL

However, the volume calculated here seems to align more closely with one of the options provided. To ensure maximum safety during treatment and account for potential fluctuations or additional factors (like ultrafiltration rates and patient well-being), many clinicians round or adjust this number as necessary.

Given the provided choices, the best fit for the calculated requirement is 2,950 mL. This figure provides a safe target that might accommodate for any extra
