Blood Borne Disease and Blood related disorders

Blood Borne Disease and
Blood related disorders

, Objectives
At the end of this chapter ,students are expected to :-
 Describe the process of haematopoiesis
 Differentiate between the hypoproliferative and the haemolytic
Anaemias
 Compare leukemias in terms of incidence, physiologic alteratio
,clinical manifestations, management and prognosis
 Use the nursing process to as a framework for care of patients
with acute leukemia
 Identify therapies for blood disorders including the nursing
implications for the administration of blood components

, CONCEPTS
 Hematocrit-percentage of total blood volume consisting
RBCs
 Hematopoiesis- complex process of the formation and
maturation of blood cells
 Haemoglobin- iron containing protein of RBCs , delivers
oxygen to tissues
 Haemolysis-destruction of RBCs
 Hypochromia-pallor within the RBC caused by decrease
oxygen- left shift increased release of immature forms o
WBC in response to need

, CONCEPTS CONT…
 Leukemia- uncontrolled proliferation of WBC,
often immature
 Leukopenia- less than normal amount of WB
in circulation
 Lysis-destruction of cells
 Haemostasis- intricate balance between clot
formation and clot dissolution
