Understanding Fluid and Salt Dynamics

What happens to the extracellular and intracellular volumes when isotonic fluid is added?

• Extracellular volume increases, intracellular volume decreases

• Both extracellular and intracellular volumes decrease

• Extracellular volume increases, intracellular volume remains unchanged

• Both extracellular and intracellular volumes increase

How does adding hypotonic fluid affect the concentration of solutes in the compartments?

• No change in concentration

• Increases concentration in extracellular, decreases in intracellular

• Decreases concentration in both compartments

• Increases concentration in both compartments

What is the effect of adding hypertonic fluid on intracellular volume?

• Intracellular volume remains unchanged

• Intracellular volume decreases

• Intracellular volume fluctuates

• Intracellular volume increases

Which type of fluid addition results in the greatest increase in extracellular volume?

• Isotonic fluid

• Hypotonic fluid

• Hypertonic fluid

• Pure water

What is the primary reason hypertonic fluid increases extracellular volume the most?

• It adds more fluid than other types

• It adds salt that draws more fluid out of cells

• It decreases intracellular volume

• It has no effect on intracellular volume
