Case #1Nephrology / Endocrinology / Emergency

📋 Case data

Volume assessmentHemodynamically stable
Acute or chronicChronic (>48 h) or unknown

Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 2 · Volume assessment

Sodium >145 — is the patient hemodynamically stable?

💡 Hypernatremia = serum sodium >145 mmol/L, usually from water deficit (inadequate intake / losses > solute), occasionally sodium excess, rarely diabetes insipidus. Assess volume and hemodynamics first.
