A Woman Running a Marathon Collapses at the Finish Line

A woman running a marathon collapses at the finish line and is rushed to the hospital. The physicians determine that she has lost a large amount of water and salts from excessive sweating. Which of the following would be an appropriate course of action?

A) Determine the woman's intracellular fluid levels so that they can provide a fluid replacement therapy that will regain isotonic conditions of salt and water.
B) Determine the woman's intracellular fluid levels so that they can provide a fluid replacement therapy that will regain hypertonic conditions of salt and water.
C) Determine the woman's intracellular fluid levels so that they can provide a fluid replacement therapy that will regain hypotonic conditions of salt and water.
D) Determine the woman's intracellular fluid levels so that they can provide a fluid replacement therapy that will provide a measure of metabolic heat production.
