The traps that quietly cost points
These are the point-loss patterns iHuman never tells you about. We map every one for this case.
⚠
Euvolemic hyponatremia with concentrated urine (Uosm > 100) = classic SIADH
⚠
Must check serum osmolality (< 275), urine osmolality, urine sodium (> 40)
⚠
Fluid restriction (800-1000 mL/day) is first-line treatment
⚠
Correct sodium slowly: ≤ 8 mEq/L per 24h — rapid correction causes osmotic demyelination
⚠
Common causes: SSRI medications, lung cancer (SCLC), CNS disorders, pain
