Urine specific gravity is a measurement of the kidney's ability to concentrate and excrete urine. Specific gravity compares the density of urine to the density of distilled water. Which is an example of how urine concentration is affected? When the kidneys are diseased, the ability to concentrate urine may be impaired, and the specific gravity may vary widely. On a hot day, a person who is perspiring profusely and taking little fluid has low urine output with a high specific gravity. On a hot day, a person who is perspiring profusely and taking little fluid has high urine output with a low specific gravity. A person who has a high fluid intake and who is not losing excessive water from perspiration, diarrhea, or vomiting has scant urine output with a high specific gravity.

On a hot day, a person who is perspiring profusely and taking little fluid has low urine output with a high specific gravity. Explanation: Specific gravity is altered by the presence of blood, protein, and casts in the urine and is normally influenced primarily by hydration status. On a hot day, a person who is perspiring profusely and taking little fluid has low urine output with a high specific gravity. A person who has a high fluid intake and who is not losing excessive water from perspiration, diarrhea, or vomiting has copious urine output with a low specific gravity. When the kidneys are diseased, the ability to concentrate urine may be impaired, and the specific gravity remains relatively constant.
