| Diagnosis of anemia is based on what 3 sources of info? |
|
Definition
| patient history, physical exam, and hematologic lab findings. |
|
|
Term
| After diagnosing anemia, what is the next step? |

| Determining the cause or etiology. |

Term
| Why is rapid blood loss more likely to cause death than slow developing anemia, even if the amount of blood lost is the same? |

|
|
Term
| In anemia, tissue acidosis occurs secondary to anaerobic glycolysis; 2,3 DPG increases within the red cell. What shift is this? |
|
Definition
| Right shift in O2 dissociation curve. |
|
|
Term
| Four factors that influence the patient's ability to adapt to anemia. |
|
Definition
| Severity of anemia, competency of cardiovascular and respiratory systems, oxygen requirement of individual, and duration of anemia. |

Term
| In order to be considered severe anemia, what should the hemoglobin value be? |
|
Definition
|
|
Term
| Would a person with a hemoglobin of 11 g/dL be considered moderately anemic? |
|
Definition
| No. Moderate anemia is hemoglobin of 7 to 10 g/dL. |
