Hyponatremia: sodium rises, symptoms persist
Educational use only. Not clinically reviewed70-year-old woman for Qualified symptom-led rescue, paired sodium and neurologic reassessment, investigation, and continuing-care handoff. About 90 simulated minutes.
What you will practise
- Arrange qualified symptom-led treatment without waiting for cause classification.
- Interpret paired pretreatment findings with diuretic and duration uncertainty.
- Keep sodium and neurologic observations distinct and current.
- Respond to persistent symptoms without declaring recovery from a sodium rise.
- Transfer unresolved symptoms and ongoing treatment review.
