The nurse suspects thаt а pаtient whо has severe sepsis nоw has disseminated intravascular cоagulation (DIC). Which finding, if observed, helps confirm this suspicion?
The red blооd cell (erythrоcyte) is importаnt becаuse of its oxygen аnd carbon dioxide carrying functions. Since hemoglobin in the erythrocytes is very much involved in both of these functions, the hemoglobin concentration of the blood is of ultimate importance. When erythrocyte formation is not normal an anemia develops. Anemias fall into two broad categories: those due to a reduction in the number of erythrocytes and those due to a cell abnormality (such as shape, size, hemoglobin content or structure). Two of the simplest tests that can help detect suspected anemias are the hematocrit and hemoglobin concentration.Hematocrit (packed cell volume) is the percentage of the blood volume composed of cells (especially erythrocytes). It is a comparison of the cellular portion of the blood to the non-cellular (plasma) portion. It does not give an indication of the size, shape or hemoglobin content of the erythrocytes. For adult males the normal hematocrit range is 40-45%, and for adult females the normal range is 38-42%. Watch this video about how to determine PCV (hematocrit), it is also explained in the text below: https://youtu.be/FYW0tohRaHMThe figure below shows how the hematocrit is determined: xid-6880138_1.png Calculate the hematocrit of the capillary tube below. xid-6880137_1.png
