Which condition is most associated with a client's increased urine specific gravity?

• A. Diabetes insipidus.
• B. Chronic kidney disease.
• C. Dehydration due to diarrhea.
• D. Hypervolemia.

Answer: (C)

Increased urine specific gravity indicates that the urine is more concentrated, which can occur in several conditions but is most commonly associated with dehydration, such as that caused by diarrhea. When a person is dehydrated, the body attempts to conserve water, leading to a higher concentration of solutes in the urine, which directly raises the specific gravity.

In cases of diarrhea, significant fluid loss occurs, resulting in dehydration. This loss prompts the kidneys to concentrate urine further to retain as much water as possible, thus increasing urine specific gravity.

Other conditions listed, such as diabetes insipidus, typically result in a lower urine specific gravity because this condition causes the body to produce a large volume of dilute urine. Chronic kidney disease can lead to variable urine specific gravity, often reflecting a reduced ability of the kidneys to concentrate urine, and hypervolemia is associated with dilute urine and thus a lower specific gravity due to excess fluid in the body.
