Question 1 of 5
The student nurse is listening to a lecture on serum electrolyte levels and the use of isotonic solutions. Which statement by the student nurse indicates that the teaching has been effective?
Correct Answer: C
Rationale: Five percent dextrose in water is an isotonic solution, which means that the osmolality of this solution matches normal body fluids. Other examples of isotonic fluids include 0.9% sodium chloride solution (normal saline) and lactated Ringer's solution. Ten percent dextrose in water and 3% sodium chloride solution are hypertonic solutions, and 0.45% sodium chloride solution is hypotonic.
