A nurse is preparing to provide care for a client in the emergency department who has syndrome of Inappropriate antidiuretic hormone (SIADH). The client has a serum sodium of 115 mEq/L (136-145 mEq/L). Which of the following IV solutions should the nurse anticipate will be prescribed?
3% sodium chloride
0.99% sodium chloride
Dextrose 59% in 0.99% sodium chloride

The Correct Answer is A
A. 3% sodium chloride is a hypertonic solution used to treat severe hyponatremia by raising the serum sodium levels rapidly.
B. 0.9% sodium chloride is isotonic and would not be sufficient to correct severe hyponatremia as quickly.
C. Dextrose 5% in 0.9% sodium chloride is not typically used for severe hyponatremia treatment.
D. Dextrose 5% in 0.45% sodium chloride is hypotonic and not suitable for treating severe hyponatremia.
