4The Intrinsic pathway is designed to generate thrombin bursts
- AVerdadero
- BFalso
5Name the three steps of Coagulation
- AInitiation
- BAmplification
- CPropagation
6What begins the Initiation phase?
- AVascular injury initiates trigger factor
- BVascular injury exposes collagen for platelets to bind
- CVascular injury causes blood cells to lyse
7Trigger factor activates VII, which activates smal amounts of
- AIX
- BX
- CXI
8X & XI bind to platelets and produce small amounts of Thrombulin
- AVerdadero
- BFalso
9Thrombin initiates Amplification
- AVerdadero
- BFalso
10The platelets act as a surface for the assembly of what factor complexes?
- AIX & VIII
- BPrethrombinase (X & V)
11What happens in Propogation
- AActivated platelets/complexes generate Thrombin Burst
- BActivated platelets/complexes generate Thrombulin Burst
- CActivated platelets/complexes generate Thromblin Burst
12What two things are required for Fibrin Clot formation?
- AFibrinogen --> Fibrin
- BF IIa
- CF III
- DF V
13Thrombin production is the crucial step in haemostasis
- AVerdadero
- BFalso
14The first step in Coagulation Disorder diagnosis is a family & drug history
- AVerdadero
- BFalso
15Name the two main clinical presentation of coagulation disorders
- ABleeding in deep tissues
- BBleeding in joints
- CFlushed skin
- DEasy cutting of skin
16Prethrombin Time is anassessment of the _ Pathway
- AExtrinsic
- BInstrinsic
17Prethrombin time is expressed as an international, normalised ratio
- AVerdadero
- BFalso
18Activated Partial Thromboplastin Time is an indicator of...
- AIntrinsic pathway
- BExtrinsic pathway
19Which of the following are not Coagulation Disorder investigations?
- AFibrinogen Assay
- BFXIII Screen
- CThrombin Clotting Time
- DFibin Clotting Time
20How do you evaluate increased prethrombin time?
- AMix with normal platelets (50:50)
- BRemove half the platelets from a sample
- CThen a Factor VII assay
21How do you evaluate Activated Partial Thromboplastin Time (APPT)?
- AMix with normal plasma
- BThen do a Factor VIII, IX, XI assay
- CThen a FXII assay
22Lack o Factor X causes no symptoms
- AVerdadero
- BFalso
23Factor I assay is used if bot PT and APTT is elevated
- AVerdadero
