Dehydrated bodies should be injected with a solution; whereas edematous bodies would be injected with a solution. why?

Dehydrated bodies should be injected with an Intravenous (IV) solution; whereas edematous bodies would be injected with an arterial solution. The reason why dehydrated bodies should be injected with IV fluids is that they will replace those fluids your body lost due to sweating, vomiting, and others. On the other hand, edematous bodies would be injected with an arterial solution because it removes discoloration of the intravascular, prevents distention, and makes additional space for fluid disinfection.
