What does increased urine specific gravity indicate?Question 8Answera.Excessively diluted urineb.Excessivly concentrated urine

Understanding Urine Specific Gravity

1. Definition of Urine Specific Gravity: Urine specific gravity is a measure of the concentration of solutes in the urine. It reflects how well the kidneys are concentrating urine.

2. Normal Range: Normal urine specific gravity typically ranges from 1.005 to 1.030. Values higher than this range indicate increased concentration.

3. Increased Specific Gravity: When urine specific gravity is increased, it indicates that the urine is more concentrated. This increased concentration can be due to several factors including dehydration, excessive fluid loss, or certain medical conditions such as diabetes mellitus or kidney disease.

Evaluation of Options

• Option a: "Excessively diluted urine" corresponds to a low specific gravity (less than 1.005).

• Option b: "Excessively concentrated urine" accurately describes a high specific gravity (greater than 1.030).

Final Answer

Thus, increased urine specific gravity indicates (b) Excessively concentrated urine.
