Mrs. Smith's target weight is 62 kg. Pretreatment weight when she came in for treatment on Monday was 67 kg. The priming saline amount is 240 mL, the rinseback amount is 200 mL, fluid from medications is 100 mL, and she is not allowed any fluids during treatment. What is the total amount of fluid weight to be removed during her treatment?

The priming saline amount is 240 mL, the rinseback amount is 200 mL, fluid from medications is 100 mL, and she is not allowed any fluids during treatment. What is the total amount of fluid weight to be removed during her treatment?

• A. 4,120 mL
• B. 5,540 mL
• C. 6,540 mL
• D. 3,300 mL

Answer: (B)

The amount to remove equals the weight you need to lose plus the fluids given during treatment. In hemodialysis, 1 kg of body weight roughly equals 1,000 mL of water, so the target is to remove 5 kg (67 kg pretreatment minus 62 kg target) → 5,000 mL. During treatment, fluids introduced are priming saline 240 mL, rinseback 200 mL, and medications 100 mL, totaling 540 mL. Add these to the 5,000 mL to remove: 5,000 + 540 = 5,540 mL. So, the total fluid weight to be removed is 5,540 mL.
