Iron/B12 deficiency Flashcards

7795196641	Zollinger-Ellison Synrome	gastric acid inactivates pancreatic proteases which impairs B12 binding to IF	0
7795198369	Blind loop syndrome	stasis; colonizing bacteria bind cobalamin Cause of B12 deficiency	1
7795200922	Diphyllobathrium latum infestation	Cause of B12 deficiency binds cobalamin and prevents absorption	2
7795210323	Pancreatic exocrine deficiency	Cause of B12 deficiency	3
7795255081	Pernicious anemia	autoimmune destruction of parietal cells so less IF and less B12 absorption in distal intestine	4
7795258523	RBC folate test	measure of folate stores in tissue less sensitive to short-term dietary effects	5
7795261382	serum folate	cheaper	6
7795261383	increased homocysteine levels	Folate deficiency	7
7795263154	inadequate diet	cause of folate deficiency	8
7795271557	Hypersegmented neutrophils	B12 deficiency	9
7795273962	neurological changes	B12 deficiency	10
7795275595	ineffective erythropoiesis	destruction of red cells in marrow can be seen in B12 deficiency retic count is low	11
7795279003	Megaloblastic anemia	B12 deficiency	12
7795281053	What does the RBC indicate?	anemia	13
7795283903	Most common cause of anemia	iron deficiency anemia	14
7795284778	reasons for iron deficiency	1. diet/malabsorption 2. GI problem/ulcers 3. menstrual bleeding 4. gastric bypass 5. pregnancy (b/c need more iron)	15
7795288257	CBC in iron deficiency	increased RDW and platelets decreased MCV, MCH, MCHC, Hgb, Hct, RBC	16
7795300388	Serum labs in iron deficiency	low serum iron and ferritin increased TIBC	17
7795302043	Non-megaloblastic anemia	Does not result from DNA synthesis impairment (EtOH, liver disease) RBC precursors are normal	18
