Question

What are the normal ranges for osmo (urine (random) and serum)?

a) Urine: 50-1200 mOsm/kg; Serum: 275-295 mOsm/kg
b) Urine: 500-1000 mOsm/kg; Serum: 250-280 mOsm/kg
c) Urine: 200-800 mOsm/kg; Serum: 300-320 mOsm/kg
d) Urine: 1000-1500 mOsm/kg; Serum: 280-310 mOsm/kg

Answer 1

The correct normal ranges for osmolality are Urine: 50-1200 mOsm/kg and Serum: 275-295 mOsm/kg, which signifies good kidney function and proper body fluid balance.

Step-by-step explanation:

Normal Ranges for Urine and Serum Osmolality

The normal ranges for urine and serum osmolality are important indicators of kidney function and the body's fluid balance. Urine osmolality can vary significantly depending on fluid intake and other factors. According to the information provided, urine osmolality ranges from a low of 50-100 mOsmol/L to a high of 1200 mOsmol/L. This range suggests that option a) Urine: 50-1200 mOsm/kg seems to be the correct range for urine osmolality. The serum osmolality is a narrower range, typically 275-295 mOsm/kg, which matches with option a) as well.
