==Question== A client's potassium level returns at 7.1 mEq/L and the ECG shows peaked T waves and a widening QRS. Which intervention should the nurse anticipate '''first'''? # Sodium polystyrene sulfonate (Kayexelate) orally # IV calcium gluconate # Nebulized albuterol # Hemodialysis '''Answer:''' 2 (IV calcium gluconate) ''Rationale:'' With ECG changes present, cardiac membrane stabilization is the immediate priority β calcium does not lower the potassium level but protects the heart from lethal dysrhythmias while potassium-shifting and potassium-removing therapies are initiated. Kayexelate and dialysis remove potassium but act too slowly to be first-line in an unstable rhythm; albuterol shifts potassium but does not protect the myocardium the way calcium does.
