| Question | Answer |
|---|---|
| Pathogenesis is defined as | the sequence of events that lead to or cause a disease |
| If a necropsy must be delayed (1-3 days), ideally the body should be | refrigerated |
| The necropsy procedure may expose personnel to biohazards such as: | fungi, bacteria, viruses |
| In the event of a rabies suspect case, | the chilled head of the animal must be submitted to the state diagnostic lab within 24 hours of animal's death |
| If a poisoning is suspected, | Any tissue lesion found should be saved in formalin. Kidney and liver biopsies should be both saved in formalin and frozen. Stomach contents, urine and serum should be collected and frozen. |
| In regards to sample collection for microbiology culture, | culture samples should be collected rapidly after necropsy is initiated |
| In regards to tissue samples, | they are most commonly preserved in 10% buffered formalin |
| When submitting samples to a laboratory, | fill out forms completely and place in a plastic bag to protect form from moisture |
| List two possible purposes for the necropsy procedure: | Evaluate the accuracy of diagnosis. Evaluate quality or outcomes of treatment on pathogenesis and animal systems. Did it help or harm. |
| List 3 pieces of protective equipment (PPE) that should be utilized during a necropsy | Rubber boots for a large animal necropsy. Mask/face shield/eye protection and apron or surgical gown. Gloves (latex/nitrile) and/or special woven ones to reduce chances of accidental cuts to the tech's hand(s) |

| A leukocyte that primarily fights parasites and mediates allergic reaction is | eosinophil |
| The percentage of whole blood that is composed of erythrocytes is measured by | PCV |
| The ideal location for identifying cells for a white cell differential is the | monolayer |
| A complete blood count (CBC) includes | Total red cell count. Mean corpuscular hemoglobin concentration (MCHC). Total white cell count with differential. |
| An automated cell analyzer | differentiates cells by size |
| The preferred anticoagulant for hematology (purple top tube) contains | EDTA |
| An elevated total White Blood Cell count (WBC) is caused by | Infection, drug reaction, inflammation |
