the primary purpose of platelet function tests is to?

• detect functional abnormalities in platelets

• determine oxygen levels
• evaluate the stability of red blood cells

• measure blood pressure

Platelet adhesiveness test is also known as the

• S a l z m a n method

• D u k e method

• Ivy method

• Hi r s c h b o e c k method

4. Bleeding Time assesses:

• Only platelet number

• Only platelet function

• Both platelet number and function

• The efficiency of the coagulation cascade

a common cause of hemorrhage that needs to be ruled out before conducting platelet function tests is?

• Hemophilia
• Vitamin K deficiency
• Liver disease
• Thrombocytopenia

bleeding time measures?

• The time it takes for a wound to heal completely.
• The amount of blood lost during an injury.
• The pressure required to stop bleeding.
• The time it takes for a small wound to stop bleeding

The duke method for bleeding time utilizes:

• A blood pressure cuff

• A lancet to make an incision

• A template to create a standardized wound

• Spring loaded blade

The ivy method for bleeding time differs from the duke method by

• Using a different type of incision

• Using a blood pressure cuff to maintain constant capillary pressure

• Measuring the time to clot formation

• Using a template to create standardized wound

Which of the following factors can influence bleeding time results

• Elasticity of skin and capillary vessels

• The amount of fibrinogen in the blood

• The presence of von willebrand factor

• THE ACTIVITY OF FACTOR VIII

Abnormal bleeding time results can be caused by

• Anemia

• Hemophilia

• VON Willebrand's Disease

• All of the above

Platelet agregometry primarily assesses

• A adhesion aggression and secretion

• The formation of a fibrin clot

• The activity of coagulation factors

• The number of red blood cells
