Glucose falls from 900 to 230—but the patient is still confused. Has the crisis really ended? Nora follows three original adult cases through HHS, DKA overlap, hyperosmolality, fluid correction, potassium safeguards, insulin and dextrose, recovery criteria, transition overlap and SGLT2-related ketoacidosis. Eight rapid decisions connect the laboratory pattern to the safest nursing response.
- Assess the whole hyperosmolar emergency: severe hyperglycemia, dehydration, osmolality, cognition and the precipitating illness.
- Correct the crisis carefully: individualize fluids, track osmotic trends, review potassium before insulin and distinguish uncomplicated HHS from DKA overlap.
- Glucose improvement alone does not establish recovery; check the full resolution cluster, safe insulin transition and an achievable sick-day plan.
