Question

What is the possible cause of low urine specific gravity in the presence of high serum osmolality?

1) Dehydration
2) Kidney dysfunction
3) Diabetes insipidus
4) Excessive fluid intake

Answer 1

Low urine specific gravity in the presence of high serum osmolality can be caused by dehydration.

Step-by-step explanation:

When there is low urine specific gravity in the presence of high serum osmolality, it suggests a possible cause of dehydration. Dehydration results in a decrease in the volume of water in the body, which can lead to concentrated urine with low specific gravity. In this condition, there is not enough fluid intake to dilute the urine and increase its specific gravity.
