Correct answer: C — Withhold finerenone and consider restarting 10 mg once daily when potassium is 5.0 mmol/L or lower

Explanation lettering: E = shown as A · C = shown as B · B = shown as C · A = shown as D · D = shown as E

B is correct. In the CKD table, potassium above 5.5 mmol/L requires finerenone to be withheld. Once potassium is 5.0 mmol/L or lower, treatment may restart at 10 mg once daily. The 6.0 mmol/L threshold and different restart boundary appear in the newer heart-failure table and are not the CKD rule examined here.
