A physician orders a hypotonic solution to a client with a fluid volume deficit. The physician is most likely to order which of the following solutions to the client?
  1. 5% dextrose in water
  2. 5% dextrose in 0.9% saline
  3. 5% dextrose in lactated Ringer’s solution
  4. 0.45% saline
Explanation
Answer: A - A 5% solution of dextrose in water is a hypotonic solution. A hypotonic solution contains less salt or more water than an isotonic solution. A 5% dextrose in 0.9% saline solution and a 5% dextrose in lactated Ringer’s solution are classified as hypertonic solutions. A 0.45% saline solution is a hypotonic solution.
