Q

what is bloods primary job?

A

transporting oxygen from the lungs and delivering it to tissue cells throughout the body

  • oxygen passes from the lungs to the blood
  • binds to the red blood cells and the hemoglobin (h g b or H g b)inside those R B Cs)
  • travels via the arteries

After delivering the oxygen (O 2) to the cells;

  • picks up carbon dioxide (C O 2)
  • carries it back to the lungs for expulsion from the body
  • travels via the veins

Q

hemolytic anemia

A

high rate of blood cell destruction

25
Q

aplastic anemia

A

lack of blood cell production

26
Q

hemorrhagic anemia

A

blood loss

27
Q

Sickle cell disease (SCD)

A

is not actually one diagnosis, but represents several genetically passed disorders of the red blood cells (RBCs)

  • normal rbcs are round, whereas an individual with SCD develops red blood cells that are a C-shaped and are unusually firm and sticky.
  • The shape of these cells resembles a tool known as a sickle.
  • they have a shorter life spa, resulting in a continuing shortage of RBCs.
  • the sticky texture of these cells also increases the opportunity for the cells to stick to the walls of the blood vessels, manifesting obstructions and an ineffective delivery of oxygen via the hemoglobin–can cause pain, infection, ect.
28
Q

H B- SS

A

a condition in which the patient has inherited two sickle cell genes (“S”) one from each parent. Commonly referred to as sickle cell anemia, this is typically the most acute form of this condition

29
Q

H b- C,HB-S,or H B- S C

A

this patient has inherited a sickle cell gene (“S”) from one parent and a gene for abnormal hemoglobin called “C” from the other parent

30
Q

H b S beta thalassemia

A

manifests when a patient inherits one sickle cell gene “S” from one parent and the gene for beta thalassemia from the other parent

31
Q

H b S D and H b S E

A

a patient inherits one sickle cell gene “S” and one gene with an abnormal type of hemoglobin “D”,”E”. or”O” it would be documented as Hb-SD, Hb-SE, or Hb-S

32
Q

Sickle cell trait (SCT)

A

develops when the patient has inherited one sickle cell gene “S” from one parent and a normal gene “A” from the other parent.

  • don’t typically exhibit any signs or symptoms of the disease. When this patient considers having children, this should be noted because this can be passed along to future children.
33
Q

Hemostatic disorder

A

failure to repair a damaged blood vessel

example- D66 Hereditary factor VIII deficiency (Classical Hemophilia)

34
Q

Thrombotic disorder

A

blood clots without reason, forming thrombi (blood clots) within the vessels, causing a blockage

example

D68.59 Other primary thrombophilia (Hypercoagulable state N O S)

35
Q

Hemophilia A (Classic Hemophilia)

A

Deficiency of clotting factor V I I I

36
Q

Hemophilia B (Christmas Disease)

A

Deficiency of clotting factor I X

37
Q

Hemophilia C (Rosenthal’s Disease)

A

Deficiency of clotting factor X I

38
Q

Acquired hemophilia (secondary hemophilia)

A

an auto immune disease where antibodies are created than attack healthy tissue, specifically clotting factor V I I

39
Q

Thrombocytopenia

A

this is a low platelet count most often due to increased platelet destruction, decreased platelet production, or malfunctioning platelets

examples

  • code category D^( Purpura and other hemorrhagic conditions
  • O72.3 Postpartum coagulation defects
  • P61.0 Transient neonatal thrombocytopenia
40
Q

Type A blood

A

only antigen A on red blood cells

-can receive a transfusion only from type A or type O

41
Q

Type B blood

A

only antigen B on red blood cells

-can receive a transfusion only from type B or type O

42
Q

Type AB blood

A

both antigens A and B

-they can receive type A blood, Type B blood or type O blood a universal recipients

43
Q

Type O blood

A

neither antigen A or B Antigens

-anyone can accept this blood type= universal donors

44
Q

R h- Negative

A

does not have the R h antigen

45
Q

R h-positive

A

does have the R h antigen

46
Q

Why is there concern about complications if an R- h negative woman gets pregnant?

A

because R h factor is inherited

  • if an R h negative woman become pregnant with an R h Positive fetus (the father is R h Positive) = complications
  • often, the placenta will prevent the mother’s blood from mixing with the baby’s blood, keeping baby safe.
47
Q

neurtrophils

A

contain enzymes that work to destroy parts of bacterial pathogens that have been consumed by phagocytes

48
Q

lymphocytes

A

are critical in the immune response

49
Q

monocytes

A

large blood cells that travel throughout the body and destroy damaged red blood cells

50
Q

eosinophils

A

destroy some parasites in addition to controlling inflammation and allergic reactions

51
Q

basophils

A

create heparin, a blood-thinning agent that prevents inappropriate blood clotting, and create histamines, involved in allergic reactions

52
Q

neurtropenia

A

bone marrow produces an abnormally low number of white blood cells

a diagnosis of neutropenia may be

  • congenital condition
  • adverse reaction to chemotherapy or other medications
  • malfunction of the hematopoiesis process
53
Q

Leukopenia

A

not enough leukocytes produced

54
Q

Leukocytosis

A

too many leukocytes produced

55
Q

Leukemia

A

a malignancy of the white blood cell resulting in the bone marrow producing abnormal white blood cells that do not function as needed. this is reported from the neoplasms section of the ICD-10-CM, specifically the C91-C95 code category

56
Q

monocytic, eosinophilic, and basophilic conditions

A

malfunctions causing too few, or too many, neutrophils and leukocytes might also occur to the other types of white blood cells

examples:
- D72.818 Other decreased white blood cell count (Basophilic leukopenia)(Eosinophililc leukopinia)(Monocytopenia)
- D72.821 Monocytosis (symptomatic)
- D72.823 Leukemoid reaction (Basophilic leukemoid reaction (Monocytic leukemoid reaction)(Neurtrophilic leukemoid reaction)

57
Q

Spleen

A
  • part of the lymphatic system, but it contains white blood cells that work to fight infection
  • damage to this organ can be caused by disease or trauma
58
Q

List some immune system conditions

A
  • immunodeficiencies
  • allergies
  • sarcoidosis
  • wiskott-aldrich syndrome
