Pick the correct answer to the following question. Write a brief statement explaining why each choice of answers is correct or incorrect.

In diabetes mellitus, because of insufficient insulin production, glucose cannot enter cells. instead it accumulates in rhe blood plasma. which of the following statements would be true under these conditions?
A. The concentration of the plasma would decrease.
B. the osmotic pressure of the plasma would remain the same.
C. Water would move out of the tissues into the plasma.
D. Tissue cells would swell.

The correct answer is C. Water would move out of the tissues into the plasma.

Explanation:

In diabetes mellitus, insufficient insulin production leads to elevated levels of glucose in the blood. This condition is known as hyperglycemia. Because glucose cannot enter cells to be used for energy, it accumulates in the blood plasma.

Now let's evaluate each choice:

A. The concentration of the plasma would decrease: This statement is incorrect. The concentration of plasma would increase due to the accumulation of glucose in it.

B. The osmotic pressure of the plasma would remain the same: This statement is incorrect. The osmotic pressure of the plasma would increase due to the increased concentration of glucose. Glucose is an osmotically active solute, meaning it will cause water to move by osmosis.

C. Water would move out of the tissues into the plasma: This statement is correct. In response to the increased concentration of glucose in the plasma, water would move out of the tissues and into the plasma by osmosis. This occurs because water moves from an area of lower solute concentration (tissues) to an area of higher solute concentration (plasma).

D. Tissue cells would swell: This statement is incorrect. In fact, tissue cells would shrink or become dehydrated as water moves out of them and into the plasma in an attempt to equalize the concentration of solutes.

Therefore, the correct answer is C. Water would move out of the tissues into the plasma, while the other statements are incorrect.
