Predict the typical expected results of clot-based PT in a patient with a platelet defect.

A patient is experiencing pinpoint petechial bruising on her upper torso. Her history revealed frequent nosebleeds during her childhood. Clot-based screening assays are within normal reference ranges, and platelet function assays are abnormal. Based on this information, what appears to be defective in this patient?

A 1 year old male is sent for a hematology consult due to excessive bruising, epitaxis, and gingival bleeding. Platelet aggregation shows the following:   Wave 1: ADP.                   Wave 2: Collagen           Wave 3: Epinephrine.    Wave 4: Ristocetin What is this patient’s most likely disorder of primary hemostasis?

In vWF disease, platelets give an abnormal aggregation result in the presence of:

A patient is known to be a chronic alcoholic. His blood is drawn, and his platelet count is 72 × 109/L. What is the most likely reason for this occurrence?

A patient has a severe headache prior to his blood draw. He takes two aspirin, and his blood is drawn. Platelet aggregation studies are performed, and one comes back abnormal. Based on this information, which agonist will show a normal aggregation pattern?

A 5 year old male is sent for a hematology consult due to excessive nose bleeds. It is noted that he has a lot of gingival bleeding and bruises easily. Platelet aggregation shows the following: Wave 1: ADP.                   Wave 2: Collagen           Wave 3: Epinephrine.    Wave 4: Ristocetin The MLS ran one more aggregation study and found no response when the patient’s platelets were mixed with a combination of ristocetin and reagent-based vWF. What is this patient’s Disorder of primary hemostasis?

An instrument report has a platelet count of 850 x 109/L. This would be interpreted as:

59. Which of the following ways to bury the dead involves using a lot of chemicals that are toxic, such as formaldehyde, to the planet and is not sustainable?

Which congenital factor deficiency rarely requires treatment and involves a deficiency of a factor belonging to the contact group?
