Evaluate the following patients presenting with acute electrolyte abnormalities. Match each patient's clinical presentation and laboratory findings with the most appropriate immediate therapeutic intervention.
- A 55-year-old with uremia presenting with altered mental status, peaked T waves, and QRS widening on electrocardiogram.Intravenous calcium gluconate to stabilize the cardiac membrane.
- A 35-year-old with severe muscle weakness, cramps, and an electrocardiogram demonstrating prominent U waves with a serum potassium of 2.2 mEq/L.Intravenous potassium chloride replacement with continuous cardiac monitoring.
- A 42-year-old with profound lethargy, severe constipation, and a corrected serum calcium of 14.5 mg/dL.Aggressive intravenous isotonic saline hydration and administration of calcitonin.
- A 28-year-old marathon runner presenting with active seizures, confusion, and a serum sodium of 112 mEq/L.Intravenous 3% sodium chloride bolus.
Cevap
Hyperkalemia with ECG changes requires calcium gluconate; severe hypokalemia requires IV potassium; severe hypercalcemia requires isotonic saline and calcitonin; and severe symptomatic hyponatremia with seizures requires 3% hypertonic saline.
Each clinical presentation represents a distinct, life-threatening electrolyte emergency requiring a specific targeted intervention to prevent irreversible morbidity or mortality.
