What measures define PD adequacy?

What measures define PD adequacy?

• A. Kt/V and clearance
• B. Dialysate color and temperature
• C. Blood glucose level
• D. Kt/V and dry weight targets

Answer: (A)

PD adequacy comes from how effectively the dialysis process removes waste from the body. The main measures used are the dialysis dose, represented by Kt/V, and the overall rate of solute removal, or clearance. Kt/V assesses how much solute—primarily urea—is cleared relative to the patient’s volume of distribution over a period, and in PD we look at weekly Kt/V to reflect the continuous nature of the therapy. Clearance measures the actual rate at which solutes are removed from the body, including peritoneal clearance and any residual renal clearance. When both the dose (Kt/V) and the total clearance meet target levels, PD is considered adequate. The other options don’t gauge solute removal or dialysis dose—dialysate color and temperature relate to safety/solution properties, blood glucose is not a measure of clearance, and dry weight targets concern fluid status rather than adequacy of solute removal.
