All of the following are signs of dehydration, except

  1. Progressive metabolic acidosis

  2. Urinary specific gravity > 1.010

  3. Urine osmolality < 300 mOsm/kg

  4. Urine sodium < 10 mEq/L

explanation

When dehydrated, patients with normal renal function will retain sodium and produce a concentrated urine. Urine osmolality is typically greater than 450 mOsm/kg in this setting. Urine sodium will be low, and specific gravity will be high.
