Which type of deficiency causes a microcytic, hypochromatic anemia?
A - eryhtropoietin B - Iron C - folic acid D - Vitamin D E - Vitamin B12 |
B -- Iron
|
|
|
Why would you get anemia with chronic kidney disease?
A - Blood loss during hemodialysis B - Reduced erythropoietin C - Reduced availability of stored iron D - Reduced vitamin B12 stores E - Reduced iron absorption F - Multiple blood draws |
A -- blood loss during hemodialysis
B -- Reduced erythropoietin C -- Reduced availability of stored iron E -- Reduced iron absorption F -- Multiple blood draws |
|
|
What type of things will most likely cause a B12 deficiency?
A - Pernicious anemia B - Gastrectomy C - Dietary deficiency D - Proton pump inhibitors E - Pancreatitis F - Ileal resection |
A -- Pernicious anemia [autoimmune disease where you dont make intrinsic factor]
B -- Gastrectomy [wouldn't have intrinsic factor or R binding protein] D -- proton pump inhibitor E -- Pancreatitis [makes proteases to cleave R protein so intrinsic factor can bind] F -- Ileal resection |
|
|
If you have adequate stores of B12, but you just had a gastrectomy, how long will it be before you have symptoms of a B12 deficiency without treatment?
A - few months B - several years |
Several years
|
|
|
What type of things will most likely cause a folic acid deficiency?
A - Methotrexate B - poor dietary intake C - proton pump inhibitor D - Sprue E - inflammatory bowel disease F - pregnancy G - Chronic alcoholism |
A -- methotrexate [used to treat psoriasis]
B -- poor dietary intake D -- Sprue [celiac disease] E -- Inflammatory bowel disease F -- Pregnancy G -- Chronic alcoholism |
|
|
If your intake of folic acid suddenly stops, how long will it be before you develop symptoms of a folic acid deficiency?
A - few months B - several years |
Few months
|
|
|
What do B12 and folic acid do?
|
they are required for DNA synthesis
|
|
|
what may happen to homocysteine levels in a patient with folic acid deficiency?
|
levels would be increased
|
|
|
what type of anemia would you see with either a B12 or folic acid deficiency?
A -- Microcytic B -- Normocytic C -- Megaloblastic |
C -- megaloblastic
|
|
|
Why are the red blood cells very large with a B12 deficiency?
A - adequate DNA synthesis, but impaired RNA synthesis B -- adequate RNA synthesis, but impaired DNA synthesis |
B -- Adequate RNA synthesis, but impaired DNA synthesis
|
|
|
Which type of deficiency can cause nerve demyelination and neurological symtoms?
A - Erythropoietin B - Folic acid C - Vitamin B12 D - Iron |
C -- Vitamin B12
|
|
|
what may happen if you treat a vitamin B12 deficiency with large doses of folic acid?
|
you may correct the anemia but it will NOT prevent neurological damage
