Which urine specific gravity would be expected in a patient admitted with dehydration?

A) 1.002
B) 1.010
C) 1.021
D) 1.030

Normal urine specific gravity ranges from 1.010 to 1.025.Specific gravity less than 1.010 indicates fluid volume excess,such as when the patient has fluid overload (too much IV fluid)or when the kidneys fail to concentrate urine.Specific gravity greater than 1.025 is a sign of deficient fluid volume that occurs,for example,as a result of blood loss or dehydration.
