Hypernatremia: water access and ongoing losses

Educational use only. Not clinically reviewed

78-year-old woman for Qualified circulation support, individualized water and loss replacement, assisted access, reassessment, and continuing-care handoff. About 255 simulated minutes.

What you will practise

Prioritize qualified circulation support without mistaking it for sodium correction.
Connect water access, continuing losses, and duration uncertainty.
Distinguish individualized water replacement, ongoing-loss care, and safe access.
Compare current sodium and bedside findings with historical observations.
Transfer unresolved hypernatremia with explicit continuing-care ownership.
