Rationale for change
"How does osmolarity change" forces the student to assume we are referring to plasma osmolarity. This edit provides more clarity to avoid confusion with the impact of secretory diarrhea on stool osmolarity. To maintain standardization the change should be additionally be implemented on all other cards with this same question structure ("How does osmolarity change with ...?").

Secretory diarrhea is characterized by active secretion of water with loss of K+ and HCO3- → no change in osmolarity




| Causes | Intracellular Fluid Volume | Extracellular Fluid Volume | Osmolarity | Hematocrit | Protein in Plasma | |
|---|---|---|---|---|---|---|
| Isosmotic Volume Expansion | Isotonic NaCl, bolus or fluids | - | ↑ | - | ↓ | ↓ |
| Hyperosmotic Volume Expansion | High Salt Intake | ↓ | ↑ | ↑ | ↓ | ↓ |
| Hyposmotic Volume Expansion | SIADH | ↑ | ↑ | ↓ | - | ↓ |
| Isosmotic Volume Contraction | Burns, Diarrhea | - | ↓ | - | ↑ | ↑ |
| Hyperosmotic Volume Contraction | Diabetes insipidus, Excessive sweating | ↓ | ↓ | ↑ | - | ↑ |
| Hyposmotic Volume Contraction | Adrenal insufficiency | ↑ | ↓ | ↓ | ↑ | ↑ |
