Q

What color would u be if u had carbon monoxide poisoning

A

Cherry red

35
Q

Carbon monoxide binds to 02

A

Thats why they look red the monoxide is poisoning the rbc. They need oxygen

36
Q

A

True

37
Q

In addition to bone marrow where else are rbc sproduced

A

Lymohatic system including spleen, thymus, nodes

38
Q

A

Neutrophils, lymphocytes,, monocytes, eosonophils basophils

40
Q

GRANpa BEN

A

Granulocytes, are basophils, eosonophils, and neutroohils

41
Q

Wbc production

A

Leukopoieses

42
Q

Erythropoietin

A

Hormone detected in oxygen stimulates kidneys that stimulates production of rbcs

43
Q

What us excess bikirubin in the blood calked

A

Hyperbilirubinemia

44
Q

If jaundice is caused by hemolysis what is it called

A

Hemolytic jaundice

45
Q

Where r platelets located

A

Produced bone marrow, they prevent blood loss cause petechiae.

46
Q

What does low platelet count cause

A

Lethal bleeding

47
Q

What 3 things stop bleeding

A

Blood vessel spasm
Platelet plug/ coagukation
Blood clot- protein fibers called fibrin

Must have all in place to stop significant bleeding

48
Q

What are antibodies in wbc

A

B cells

49
Q

Bleeding dic

A

Dic bleeding disorder during sever infection . Means all clotting factors used up. Pt bleeds out. Must replace clotting factors rapidly.

50
Q

What dies exercise do?

A

Decreases patelet adhesivness decreases clotting cascade

51
Q

What is tpa

A

Tissue plasminogen activator

Initiates clot activity when u have an injury

52
Q

What do u guve mom for rh issues

A

Rhogam

53

When u give blood what should u do

A

Type and cross for the donor

54
Q

Whonis universal donor

A

O negative

55
Q

When giving blood start to have reaction

A

Spleen

67
Q

Inside vessel produces heparin what happens if vessel clotted up

A

Stops producing heparin

68
Q

List clotting cascade

A
  1. Body injured
  2. Causes body make prothrombin
  3. Prothrombin combines w calcium, platelets,
  4. Makes thrombin
  5. Thrombin develops fibrinogen
    Makes fibrin- trap blood to develop clot, sqeezes waterto heal injury n stop bleeding
69
Q

How is clotting dissolved

A

Fibrinolysis
Plasmin dissolves clot
Produces plasminogen
Clears out of body
