A patient who has been in the intensive care unit for 17 days develops hypernatremic hyperosmolality. The
patient weighs 132 lb (59.9 kg), is intubated, and is receiving mechanical ventilation. The serum osmolality is
320 mOsm/L kg H2O. Clinical signs include tachycardia and hypotension. The adult-gerontology acute care
nurse practitioner's initial treatment is to:
reduce serum osmolality by infusing a 5% dextrose in 0.2% sodium chloride solution
reduce serum sodium concentration by infusing a 0.45% sodium chloride solution replenish volume by infusing
a 0.9% sodium chloride solution
replenish volume by infusing a 5% dextrose in water solution.
