QUIZ #1 – AKI

Citrate accumulation during RCA-CRRT

Correct answer: A

Explanation: Accumulation of calcium–citrate complexes can be diagnosed in metabolic acidosis with elevated strong ion gap, hypocalcemia, and an increased total/ionized calcium ratio. Elevated lactate indicates risk of Ca–Ci accumulation but not necessarily ongoing accumulation.
