| Question | Answer |
|---|---|
| Natural hemostasis | Clot formation or vessel spasm |
| Artificial hemostasis | Compression or ligation |
| Four factors for hemostasis to occur | Adequate numbers of platelets Platelet normal function Vascular integrity All coagulation factors present |
| Coagulation | Formation of a clot |
| Number of clotting factors | 13 |
| Clotting factors are... | proteins |
| Intrinsic pathway is located | intravascular system |
| Extrinsic pathway occurs | Tissue system |
| The key to the clotting mechanism | Thrombin |
| Factor VIII | von Willebrands |
| Factor I | Fibrinogen |
| Factor II | Prothrombin |
| Qualitative | pertaining to observations of a categorical nature |
| Quantitative | pertaining to observations of a numerical nature |
| Coagulopathy | Any disorder of blood coagulation |
| Tubes that "tie up"/bind calcium to prevent the coagulation cascade | Btt-Sodium Citrate & Ltt- EDTA |
| Blood to anticoagulant ratio | 9:1 |
| EDTA/LTT tube for | Platelet counts |
| BTT/Sodium Citrate | Coagulation testing/Evaluation of intrinsic and extrinsic pathways |
| Platelet Poor Plasma | Coagulation testing |
| Platelet Rich Plasma | Platelet Function Testing |
| Whole Blood Clotting Time is also called the | Lee-White method |
| Activated Clotting Time | Intrinsic clotting mechanism |
| ACT activating agent: | Diatomaceous Earth |
| ACT normal value | 60-90seconds |
| Buccal Mucosa Bleeding Time (normal time) | 1-5min. (1-3) |
| BMBT prolonged with | platelet defects, increased capillarity fragility, Von Willebrands |
| OSPT normal range | 7-10 seconds |
