If a patient becomes dehydrated, the percentage of plysma in a centrifuged sample of his or her blood would likely A Increase. B not change. C decrease.

## Step 1<br />Plasma is the liquid component of blood, which is mostly water (about 90% to 92%) but also contains proteins, electrolytes, and other substances. <br /><br />## Step 2<br />When a person becomes dehydrated, the total volume of blood plasma decreases. This is because the body loses water, which is a major component of plasma.<br /><br />## Step 3<br />When blood is centrifuged, the components separate based on their densities. The denser components, such as red blood cells, settle at the bottom, while the less dense components, such as plasma, rise to the top.<br /><br />## Step 4<br />Given that the total volume of plasma decreases due to dehydration, the percentage of plasma in a centrifuged sample of blood would also decrease. This is because the volume of plasma is now a smaller proportion of the total blood volume.
