Hematology Flashcards
CDC recommendations for the pneumonia vaccine
initial vaccine with PCV13 at 65 then one year later with PPSV23
MCH interpretation in CBC labs
MCH indicates the degree of hemoglobin incorporated into red cells.
MCH low Hypochromic anemia
MCH high Hyperchromic anemia
MCH normal normochromic anemia
normal value 27-31
MCV
Normal value 80-95
describe the size of Red blood cells.
<80 microcytic anemia
80-95 normocytic anemia
>95 macrocytic anemia
the 3 most common cause of bacterial diarrhea in the US are
A routine stool culture will identify Salmonella, Campylobacter, and Shigella,
Folic acid and vB12 deficiency anemia are
Macrocytic anemia
MCV>95
Lead toxicity Sideroblastic anemia, Thalassemia, and Iron deficiency anemia are
Microcytic anemia
MCV <80
Methotrexate impaired metabolism of
folic acid
so folic acid should be order to a pt who is takin methotrexate to prevent folic acid deficiency
serum iron
measure of iron in circulation
serum ferritin
measure of iron in storage
ferritin is the protein that stores iron
IDA clinical presentation
most people are asymptomatic until 30/10
Young, middle, and adult: fatigue, weakness, irritability, exercise intolerance, HA.
Older adult: exacerbation of comorbidities (angina, dementia, heart failure)
pt with IDA should received iron supplement for how long
4-6 months
In pt with IDA normal labs, result indicated that iron supplements could be stopped
serum ferritin level
Thalassemia anemia characteristic
Microcytic/hypochromic
inherited
dx test Hgb electrophoresis
treatment consider reproductive counseling
MCV/MCH low
IDA
MCV/MCH low
RDW high
Fe low
serum ferritin low
Spoon nail
Let’s talk about spooned nails, or koilonychia, which is when your actual nail starts bending backwards. At its root, a problem with spoon-shaped nails signifies a larger iron deficiency in the body.
