DaVita Peritoneal Dialysis (PD) Practice Exam 2026 - Free Dialysis Practice Questions and Study Guide

In PD adequacy, weekly Kt/V urea measures how much urea is cleared relative to the patient’s total body water over a week. The total clearance comes from two sources: the peritoneal dialysis exchanges and any residual renal function. Because both contribute to removing urea, the target is set for the combined (total) weekly Kt/V, not just PD alone. The standard minimum target is 1.7 per week when including residual renal function. If a patient has little or no residual function, the PD regimen must provide most of that clearance to reach 1.7; with more residual function, less PD clearance is needed. The other options set targets that are either too low or unnecessarily high for a minimum standard.
