Which clinical manifestation indicates the need for immediate hemodialysis in a client with chronic kidney disease?

• A. Acidosis
• B. Ascites
• C. Hyperkalemia
• D. Hypertension

Answer: (C)

Hyperkalemia is the clinical manifestation that most clearly signals an immediate need for hemodialysis in chronic kidney disease. When kidney function is impaired, potassium accumulates, and high potassium levels can rapidly disrupt the heart’s electrical activity, leading to dangerous arrhythmias. Dialysis removes potassium from the blood quickly, providing urgent stabilization. While severe acidosis or other CKD findings like ascites or hypertension are important, they don’t pose the same immediate life-threatening threat as hyperkalemia requiring prompt dialysis. If potassium is markedly elevated (around 6.0 mEq/L or higher) and especially with any ECG changes, urgent dialysis is indicated.
