What is one of the criteria for a patient to be considered for dialysis?

The correct answer is based on the recognition that dialysis may be indicated when patients experience significant electrolyte imbalances. Hypercalcemia, or elevated calcium levels in the blood, can lead to severe complications, including cardiac arrhythmias and renal failure. In cases where standard measures to correct this imbalance are ineffective, dialysis can be employed to rapidly decrease the calcium levels and restore normal physiological function.

While hypertension management and stable glucose levels are important factors in a patient's overall health, they are not direct criteria for dialysis initiation. Similarly, normal urine output typically indicates adequate kidney function, which would often mean that dialysis is not necessary. The consideration for dialysis often arises in response to severe abnormalities in electrolytes, making electrolyte imbalances a critical factor in determining the need for renal replacement therapy.
