The correct answer for this question is "more water is lost than enters the body". Isotonic Fluid Loss can also be referred to as Dehydration. Dehydration is the state of losing too much water than absorbing the required water that the body needs. Based on the given situation, a patient with flu and reports about five to six loose stools a day can lead a patient to dehydration because of his continuous pooping. Water lost must be replaced, so that the patient won't be dehydrated.
