The nurse points out that electrolytes are essential for health. Nonelectrolytes include:
Correct answer
D
Rationale
The correct answer is D: Glucose. Glucose is a nonelectrolyte because it does not dissociate into ions in solution. Electrolytes, such as sodium and potassium, dissociate into ions and conduct electricity. Amino acids, magnesium, and phosphates are electrolytes as they dissociate in solution. Glucose, being a sugar molecule, remains intact and does not contribute to the electrical conductivity of a solution. Therefore, it is classified as a nonelectrolyte.
