Which of the following is true?

a. Urine osmolality in adults cannot be compared to urine osmolality in children.

b. Urine osmolality varies equally among adults as in children.

c. Urine osmolality varies more among adults than children.

d. Urine osmolality varies more among children than adults.

Answer: d. Urine osmolality varies more among children than adults.

Explanation:

Urine osmolality is a test that tests the dissolved particles in the urine per unit of fluid, allowing urinary concentration disorders such as diabetes to be diagnosed and hydration status to be assessed.

Urine osmolality varies with age in young children, and adults have a greater concentrating ability than neonates, so age must be considered when analyzing the results.
