Hematology Flashcards
Blood loss of 15% or higher results in what?
orthostatic hypotension
when checking a CBC, the initial H&H during active bleeding may be?
in the normal range
the normal bone marrow will respond to blood loss by releasing what?
immature RBC, reticulocytosis
An absolute neutrophil count of less than 1500 is what?
neutropenia
individuals with what condition have frequent infections (especially bacterial) with sx of fever, sore throat, oral thrush, and so forth
neutropenia
gradual onset of symmetrical peripheral neuropathy is a symptoms of what
vitamin b12 deficiency
A cancer of the beta lymphocytes (B cells)
hodgkin’s lymphoma
symptoms of hodgkin’s lymphoma
night sweats, fevers, and pain with alcohol consumption; generalized pruritus with painless enlarged lymph nodes (neck), anorexia, weight loss
Identified by the presence of Reed-Sternberg cells
Hodgkin’s lymphoma
a cancer of the lymphocytes (usually B cells) and killer cells
non-hodgkin’s lymphoma
symptom’s of non-hodgkin’s lymphoma
night sweats, fever, weight loss, generalized lymphadenopathy (painless)
usually occurs in the older adults and has a poor prognosis
non-hodgkin’s lymphoma
cancer of the plasma cells
multiple myeloma
symptoms of multiple myeloma
fatigue, weakness, and bone pain that is usually in the back or chest
causes proteinurua with Bence-Jones proteins, hypercalcemia, normocytic anemia
multiple myeloma
platelet count less than 150,000
thrombocytopenia
the gold standard test to diagnose hemoglobinopathies such as sickle cell and thalassemia
hemoglobin electrophoresis
chronic smokers, individuals with long-term COPD, long term residents of high altitudes or EPO treatment have a higher incidence of what
secondary polycythemia
microcytic, hypochromic anemia (most common)
iron deficiency anemia
pallor of the skin, conjunctiva and nails beds, complaints of daily fatigue, exertional dyspnea. may have glossitis (sore and shiny red tongue) and angular cheilitis (irritated skin or fissures at the corners of the mouth), cravings for pics, spoon-shaped nails, systolic murmurs, tachycardia, and heart failure
symptoms of IDA
etiology of IDA
blood loss, heavy menses, pregnancy, poor diet, GI blood loss, postgastrectomy
Treatment for IDA
iron rich foods, identify cause of anemia, supplementation
which foods are high in iron
organ meats, red meat, dried peas and beans, dark green leafy vegetables, whole grains
what is the average lifespan of an RBC
100-120 days
how much elemental iron must be given for supplementation for IDA
150-200 mg of ELEMENTAL iron
How long does a patient need to be on iron supplementation for IDA
at least 4-6 months to rebuild iron stores
microcytic hypochromic anemia (next most common)
thalassemia
a genetic disorder in which the bone marrow produces abnormal hgb
thalassemia
common in mediterranean decent
thalassemia
3 criterion for anemia
- hemoglobin
- hematocrit
- RBC count
Name 3 reasons people become anemic
- blood loss
- bone marrow not producing RBCs
- increased destruction of RBCs
How does poorly managed chronic disease affect the H&H
reduce them
Those who live in high altitudes like Denver, CO tend to have _(higher or lower)__ hemoglobin and hematocrit
higher
what part of the CBC describes the size of the RBC
MCV (think V volume/size)
