Terms in this set (87)
leukopenia - decrease in all WBCs (neutrophils most common)
- below 4,000/mcL
- increases risk of infection
- decreases signs of infection
- diminishes healing ability
leukocytosis - a rise in WBC count above 11,000/mcL
leukemoid reaction - leukocytosis in excess of 50,000/mcL because of
disorders other than leukemia
- seen in hemorrhage, specific infections, splenic
dysfunction and organ necrosis
, anemia - insufficient delivery of oxygen to the tissues caused
by an inadequate number of mature, healthy RBCs in
the blood
- produce signs of cellular hypoxia and lack of cell
energy
- lack of iron, B12, folic acid (necessary for
synthesizing RBCs)
hypoxia - what is the major stimulus for erythropoiesis?
kidney - which body structure can sense hypoxia in the
blood and releases hormone erythropoietin, which
stimulates the bone marrow to synthesize RBCs from
stem cell erythroid precursors?
iron - the synthesis of Hgb is greatly dependent on the
availability of which nutrient?
- a lack of _ results in small amounts of Hgb in each
RBC resulting in low amount of oxygen carriage in
blood
cellular hypoxia - if oxygen saturation is 100% and Hgb is low (anemia),
oxygen delivery will be inadequate resulting in _?
acute blood loss - anemia of _ is a precipitous drop in the RBC
population caused by hemorrhage
- recent trauma is a major risk factor
acute blood loss - signs and symptoms of this condition depends on
the volume lost
- hypotension, tachycardia, tachypnea, pallor, loss of
consciousness develop as bleeding worsens
