While reviewing lab results, the nurse recalls the most abundant cells in the blood are: ?

The answer is Erythrocytes.

There are about 4,000,000 - 6,000,000 erythrocytes per microliter of the blood.
There are about 5,000 - 10,000 leukocytes per microliter of the blood.
There are about 150,000 - 400,000 thrombocytes per microliter of the blood.
Therefore, the most abundant cells in the blood are erythrocytes.

The correct answer to this question is hypertonic. A patient is in need of hydration. The patient's cells will be most likely hypertonic. The solution inside the cells is in need of a greater concentration that leads into hypertonic cells.
