Pharmacological and Parenteral TherapiesQuestion 212 of 2368
A client has hypernatremia with confusion and severe thirst. Which IV solution does the nurse expect to be prescribed?
- 3% sodium chloride
- 5% dextrose and lactated Ringer's
- 0.9% sodium chloride
- 0.45% sodium chloride
Show answer
Correct answer: 0.45% sodium chloride
Hypernatremia is treated with less sodium intake, more water and a hypotonic IV solution. Hypertonic solutions would worsen it.
