Clin Path And Hematology Flashcards
Lactate is a reflection of -, how?
Reflection of anaerobic metabolism - kept is produced from pyruvate in anaerobic environments to keep glycolysis going
What can you measure to assess perfusion
Lactate - Normal is 2.5
Polychromasia is a sign of
Regenerative anemia - immature RBCs, being released into circulation
How can you raise PCV 1%
Give 1 ml /kg of packed RBCs
When do you give a blood transfusion
If PCV is less than 20% with acute blood loss
Describe major cross matching
Donor RBCs to recipient plasma
Describe minor cross matching
Donor plasma to recipient RBCs
What are the most clinically relevant blood hypes in the
B and J
What coag pathways are evaluated with pt and PTT
Pt - extrinsic and common
PTT - inhinail and common
What does the buccal mucosal bleeding time assess
Platelets
What can you measure besides pt and ptt if you are concerned about DIC
Antithrombin time
What can you measure besides pt and ptt if you are concerned about DIC
Antithrombin time
If you have hypocalcemia - what else should you check for and why
Check for hyproproteinemia because calcium measured on chemistry is protein bound - double check if real with an ionized calcium
What are common causes of hypocalcemia
Eclampsia, renal disease, phosphate enema toxicity, ethylene glycol toxicity
What are common causes of hypercalcemia
Neoplasia, primary hyperparathyroidism, chronic renal failure, hypervitaminisis D

What does normal joint fluid contain on cytology
Small mononuclear cells without neutrophils
Joint said full of mostly neutrophils indicates
Supportive inflammation
Describe a granulomatous inflammation
Mostly monocular cells - lymphocytes, macrophages, plasma cells
Describe a pyogranulomatous joint fluid
Mix of neutrophils and mononuclear cells
How can you confirm an immune mediated thrombocytopenia
Spherocytes on a blood smear
How do we treat IMTP
Azathioprine - immunosuppresive drug
