A clinically stable haemodialysis patient has persistent hypertension and uncertain target weight. Bioimpedance suggests extracellular fluid excess, but removing the full estimated excess in one treatment would require a high ultrafiltration rate. What is the best approach?

Correct answer: C — Reduce target weight gradually using bioimpedance as an adjunct

The best answer is “Reduce target weight gradually using bioimpedance as an adjunct”. UKKA supports supplementing uncertain clinical assessment with bioimpedance, but the target-weight adjustment must be individualised and paced to avoid excessive ultrafiltration and treatment intolerance. “Remove the full estimated excess in the next treatment” is less appropriate because a large single-session change can produce excessive ultrafiltration and intradialytic hypotension “Ignore bioimpedance because clinical examination is definitive” is less appropriate because UKKA considers objective measures useful adjuncts when clinical assessment is uncertain “Increase target weight until predialysis blood pressure normalises” is less appropriate because this would worsen the suspected volume excess rather than test it safely “Shorten treatment time while removing the same fluid volume” is less appropriate because this raises the ultrafiltration rate and haemodynamic risk
