What Change in Fluid Concentration Leads to Water Intoxication

Question

What change in fluid concentration leads to water intoxication?
A) Hypertonic extracellular fluid
B) Hypotonic extracellular fluid
C) Isotonic intracellular fluid
D) Hypertonic intracellular fluid

Accepted Answer

Water intoxication occurs when there is a dilution of the electrolytes in the body, leading to hypotonic extracellular fluid. This condition happens when the intake of water is excessively high, diluting the sodium levels outside the cells, causing water to move into the cells to balance the concentration, which can lead to swelling and potentially dangerous health effects.
