Primary Care: Hematologic Conditions Flashcards
(41 cards)
What is Anemia (non pregnant)?
Decrease in red blood cell mass or decrease in hemoglobin. Hemoglobin level less than 12
Signs of Anemia
pallor, jaundice, Orthostatic hypotension, peripheral edema, pale mucous membranes and nail beds, smooth, sore tongue, splenomegaly, tachypnea, dyspnea on exertion, tachycardia or flow murmur
Symptoms of Anemia
Fatigue, drowsiness, weakness, dizziness, headaches, malaise, pica, poor appetite, changes in food preferences, changes in sleep habits, changes in mood
Microcytic anemias
iron deficiency, thalassemias, and anemia of inflammation
Macrocytic anemias
folate and vit b12 deficiency, anemia associated with liver disease, increased reticulocyte production, and some medication effects
Normocytic anemias
acute blood loss or conditions such as sickle cell disease, hemoglobin C disease, or glucose-6-phosphate dehydrogenase (G6PD) deficiency.
Aplastic anemia
normocytic but characterized by pancytopenia, reduction in the number of red blood cells (RBCs), white blood cells (WBCs), and platelets.

Chronic Disease
First level of assessment to help differentiate many underlying causes of anemia
CBC
Most sensitive and specific predictor of iron stores; true iron defiency
ferritin level
Recommended intake of iron for 14 to 18 years
15 mg
Recommended iron from 19 to 50
18 mg
Most common causes of iron deficiency anemia in adults
occult blood loss, excessive menstrual loss, and inadequate nutritional intake
Ferritin level that confirms diagnosis of iron deficiency
less than 100-150
Severe anemia
< 9.0
First line tx of iron def anemia
dietary intake of iron risk foods, consumption of vit C- enriched products to enhance absorption of the heme iron
Iron rich foods
green leafy veggies, collard greens, egg yolks, raisins, prunes, liver, oysters, some fortified cereals
Taking iron preparations will..
decrease absorption but will improve GI effects
Antacids will do what to iron supplement absorption
decrease it, should not be taken at the same time
Sickle cell disease
Hb SS, severe illness, sickle cell crisis
