    • soft tongue
    • angular chelitis
  47. What kinda tests can you do to me to find out if i have iron anemia?
    Serum folate

    CBCw/differential
  48. What is the person lacking in vit B12 anemia?
    intrinsic factor. it's used to absorb vit b12.
  49. Vegetarians are at risk for what kinda anemia?
    pernicious anemia because they lack vit b12.
  50. What is a common neurologic SE of pernicious anemia?
    ataxia.
  51. What cranial nerves can pernicious anemia (vit b12) affect?
    7,9,10/ 1,2,3
  52. What is the schelling test used to look for pernicious anemia (vitb12)?
    radioactive vit b12. if pee isn't radioactive, then body didn't absorb it and run it through the loops.

    if it is radioactive, then body ran it thorugh its course and you know it isn't pernicious anemia. 
  53. I have pernicious anema (vitb12). I have a folate deficiency. What can I do?
    Eat fruits and vegies. IV folate is only if yo uhave absorption probs.
  54. I have pernicious anemia (vitb12). I have a vitb12 deficiency. What can I do?
    Monthy IV of B12. Have to be for life. of Blood transfusion.
  55. Is sickle cell autosomal or sex-linked?
    Auto
  56. What kinda races are at risk for sickle cell?
    • black
    • middle east
    • mediterranean
    • aboriginal
    • (DARKNESSESS)
  57. Sickle cell can bring about vaso occlusive disease. What is that? How can I fix that? What can I do to avoid that?
    When then sickle cells occlude vessels, leading to ichemia. Pain will occur. Use NS or opiods. 

    Avoid the cold. hypoxia. dehydration. 
  58. How does the doctor find out if i have sickle cell?
    hemoglobin electrophoresis
  59. What kinda drugs are out there for me to take for sickle cell?
    •Hydroxyurea (Hydrea), a chemotherapy agent, has been shown to be effective in increasing or reactivating fetal hemoglobin levels in patients with sickle cell anemia, thereby decreasing the formation of sickled cells. 

    •Arginine has anti-sickling properties and enhances the availability of nitric oxide, the most potent vasodilator, resulting in decreased pulmonary artery pressure. Arginine may be useful in managing pulmonary hypertension and acute chest syndrome
