The normal range of serum osmolality (in mosm/L) is_____________?
Correct answer: B. 280 to 295
- A. 300 to 320
- B. 280 to 295
- C. 350 to 375
- D. 200 to 250
Explanation
Normal plasma or serum osmolality is approximately 280 to 295 mOsm/kg, often rounded similarly in questions using mOsm/L. Values above this range indicate hyperosmolality, while lower values indicate hypo-osmolality.
