Match the type of dehydration with the correct definition below. - Correct Answer Isotonic - The
interpretation of the patient's lab work indicated they lose fluid and electrolytes equally.
Hypotonic - The interpretation of the patient's lab work indicated they lost more electrolytes than
fluid were lost.
Hypertonic - The interpretation of the patient's lab work indicated they lost more fluid than
electrolytes were lost.
