Which is a classic indication to initiate dialysis in CKD?

• A. Refractory uremic symptoms
• B. Mild hyperkalemia
• C. Normal metabolic status
• D. Adequate diuresis

Answer: (A)

The main concept here is that dialysis is started when uremic symptoms cannot be controlled with medical therapy. When kidneys fail, uremic toxins build up and can cause serious symptoms such as confusion, nausea, vomiting, anemia-related fatigue, or even pericarditis. If these uremic symptoms persist despite optimal medical management, dialysis is needed to rapidly remove toxins, correct electrolyte and fluid imbalances, and improve the patient’s overall condition.

The best choice reflects that scenario: symptoms attributable to uremia that remain refractory to conventional treatment. Mild hyperkalemia, by contrast, can often be managed with medications and dietary adjustments unless it is severe or resistant to treatment, so it doesn’t automatically require dialysis. Normal metabolic status indicates no active metabolic disturbances that dialysis would correct, and adequate diuresis means the kidneys still produce enough urine to manage waste and fluid, so dialysis isn’t indicated.
