Final answer:
Mr. Ramirez is being given an isotonic saline solution to replenish fluids and electrolytes lost due to severe heat exhaustion.
Step-by-step explanation:
The solution being administered to you, Mr. Ramirez, is an isotonic saline solution, which is a lot like the fluid outside your cells. Its primary function is to replace the fluids and electrolytes that your body has lost due to severe heat exhaustion. There aren't any proteins like those found in blood or medications to prevent water loss; it is simply a balanced mix of water and salts, most notably sodium chloride (NaCl), that helps to restore your body's fluid balance.
