| Tachycardia, hypotension (low blood pressure), severe weakness, loss of breath, and volume loss are all signs of __ __. | severe anemia |
| Other tests for anemia include: | urinalysis, parasite exam, occult blood (meaning stool, rectal exam) |
| If a patients HGB is between 7 - 10, they have __ __. | moderate anemia |
| The rule of 3 says that HGB should be __ times the level of RBCs. | three |
| The rule of 3 says that HCT should be __ times the level of HGB. | three |
| The MCV is a measure of the __ __ of an eythrocyte. | average volume |
| What is the normal range for an MCV? | 80 - 96 fl |
| MCV is determined by multiplying __ by 10 and dividing the result by the __. | HCT, RBC |
| MCH expresses the __ __ of hemoglobin in an average erythrocyte. | average weight |
| MCH is directly proportional to the amount of __ and the __ of the erythrocyte. | HGB, size |
| MCH is determined by multiplying the __ by 10 and dividing the result by the __. | HGB, RBC |
| MCHC is the average __ of hemoglobin per unit volume of erythrocytes. | concentration |
| MCHC is the ratio of the __ or hemoglobin to the __ of the erythrocyte. | hemoglobin, volume |
| The normal range for MCH is? | 27 - 32 pg |
| The normal range for MCHC is? | 32 to 36 g/dl |
| MCHC is determined by multiplying HGB by __ and dividing the result by the __. | 100, HCT |
| Red cell distribution width (RDW) is an index of the variation in cell __ within the red cell population. | volume |
| Normal RDWs are __. | homogenous |
| Red cell populations with higher than normal RDW are termed __. | heterogenous |
| RDW can be the first test result to __ with changes in RBC population sizes. | increase |
| RDW is determined by dividing __ by the standard deviation of red cell volume. | MCV |

| A normal retic count for newborns is between __ and __ percent. | 1.8 and 5.8% |
| Retic counts are made by mixing __ amounts of blood and new methyline blue (or another supravital stain). | equal |
| When seen under a Wright's stain, retics appear __. | polychromatic |
| Supravital stains allow cells in the sample to remain __. | alive |
| To determine a patient's corrected retic count, you divide the patient's __ by whatever HCT is __ for their gender and age. | HCT, normal |
| RPI stands for __ __ __. | retic production index |
| Premature retics remain in the blood and take from __ to __ more days to mature. | 1, 1.5 more days |
| Prematurely released retics will cause the __ __ count to be elevated. | corrected retic |
| To find the RPI, you must divide the __ __ by the __ __ in days. | corrected retic by the maturation time in days |
