Which urine characteristic is typically decreased in dehydration?

Which urine characteristic is typically decreased in dehydration?

• A. pH level
• B. Specific gravity
• C. Urine volume
• D. Bilirubin levels

Answer: (C)

In the context of dehydration, urine volume is typically decreased due to the body's attempt to conserve water. When an individual is dehydrated, the kidneys respond by concentrating the urine to minimize water loss, resulting in lower urine output. This is a key physiological response, as it helps maintain electrolyte balance and hydration status. While the specific gravity of urine may increase due to concentration, and pH can be influenced by various factors, the primary and most direct effect of dehydration is the decrease in urine volume. Bilirubin levels can also be affected under different conditions, but they are not specifically related to hydration status. Therefore, the characteristic most indicative of dehydration is the reduction in urine volume.
