Correct answer: D — 1.7

UKKA PD guideline recommends a minimum combined weekly Kt/V of 1.7 for peritoneal dialysis (peritoneal clearance + residual renal function). As residual function declines, the PD prescription must be intensified to maintain this target. This patient's combined Kt/V of 1.5 is below target. Options include increasing exchange volume, adding an extra exchange, switching from CAPD to APD (or vice versa), or increasing dwell times depending on transport status.
