Correct answer: C≥1.2 (minimum 1.2 per session)

UKKA (UK Kidney Association) haemodialysis guideline recommends a minimum delivered spKt/V of 1.2 per session for thrice-weekly haemodialysis. The patient's spKt/V of 1.0 is subtherapeutic, which likely contributes to her elevated pre-dialysis solute levels. Dialysis prescription should be optimised by increasing session duration, blood flow rate, or dialyser size.
