Correct answer: E — Use Cockcroft–Gault and product-specific criteria
DOAC dosing should be checked using Cockcroft–Gault creatinine clearance because this was used in pivotal trials and product licences. Apixaban criteria also depend on indication and, for atrial fibrillation, age, weight and serum creatinine; severe renal impairment has additional product-specific instructions. An isolated eGFR of 35 is not enough to make the original categorical statement safely. The competing options do not fit the renal phenotype, temporal relationship, treatment threshold or safety constraint described. Management still requires confirmation of current medicines, renal trajectory and relevant contraindications, followed by timely biochemical and clinical reassessment. Escalate urgently if life-threatening electrolyte disturbance, respiratory compromise, shock, neurological deterioration or a dialysis indication develops.
