[RECALLS] Batch 2022 - 1st Evals Blood

Question 1

Most potent protease in coagulation

pathway

Answer 1

Thrombin

Question 2

Tolerance of self-antigen is abnormal

Answer 2

False

Question 3

In renal failure, there is a total absence of erythropoietin

Answer 3

False

Aside from the kidneys, the liver can also produce EPO.

Question 4

Surface of T-Helper cell

Answer 4

CD4+

Question 5

Factor that cleaves C3

Answer 5

C3bBb

Question 6

50-kg woman who experienced 10%

blood loss. How much blood was lost?

Answer 6

350 mL

(Women have approximately 70mL/kg of blood, while men have 80mL/kg. To compute for the blood loss, you can multiply 70mL/kg by 50kg. This
will give you 3,500 mL of total blood volume. Get 10% of that value to determine the volume of blood lost.)

Question 7

Thrombus at popliteal vein

Answer 7

Fibrin

(Thrombus in arteries tends to have more platelets than thrombus in veins. Thrombus in veins tends to have more fibrin than thrombus in arteries.)

Type 1

hypersensitivity
