A female patient has a hemoglobin of 6.4 g/dL and is preparing to have a blood transfusion. Why would it be important for the nurse to obtain information about the patient's history of pregnancy prior to the transfusion? - A high number of pregnancies can increase the risk of reaction - If the patient has never been pregnant, it increases the risk of reaction - Obtaining information about gravidity and parity is routine information for all female patients -n If the patient has been pregnant, she may have developed allergies

- A high number of pregnancies can increase the risk of reaction

Prior to administration of a transfusion of PRBCs, what action should the nurse perform?

Assess vital signs to establish baselines.

decreased fibrinogen.

Liver disease Advanced Cancer Malnutrition

Elevated/decreased HCT count

Same as HGB

Persistently elevated hematocrit is an indication

therapeutic phlebotomy

A patient receiving plasma develops transfusion-related acute lung injury (TRALI) 4 hours after the transfusion. What type of aggressive therapy does the nurse anticipate the patient will receive to prevent death from the injury? (Select all that apply.) - Performance of serial chest x-rays - Supplemental oxygen - Provision of intravenous fluid support - Intubation and mechanical ventilation - Intra-aortic balloon pump

- Supplemental oxygen - Provision of intravenous fluid support - Intubation and mechanical ventilation

Responsible for humoral immunity; many mature into plasma cells to form antibodies

B lymphocyte

Contains histamine; integral part of hypersensitivity reactions

Basophil

elevated fibrinogen

Acute inflammation, infection, heart disease

Plasma protein responsible for fluid balance

Albumin

the role of B lymphocytes

Antibody production B lymphocytes are capable of differentiating into plasma cells. Plasma cells, in turn, produce antibodies.

Anticoagulation therapy

decrease INR

Cancer

decreased aPTT count

Cancer

increased PT Count time

Iron deficiency anemia Chronic Blood loss Inadequate diet of iron

Integral component of immune system

Lymphocyte

integral part of the immune system

Lymphocyte

Decreased TIBC

Malnutrition, cirrhosis, pernicious anemia

elevated MCV

Microcytic RBC Megaloblastic Anemia

Enters tissue as macrophage; highly phagocytic, especially against fungus; immune surveillance

Monocyte

Largest classification of Leukocyte

Monocyte

Preventing or limiting bacterial infection via phagocytosis

Neutrophil

What age-related change in hematologic function should the nurse integrate into care planning for an older adult who has a hematologic disorder?

Older adults are less able to increase blood cell production when demand suddenly increases.

Secretes immunoglobulin (antibody); most mature form of B lymphocyte

Plasma cell

A lymphoid stem cell defect has the potential for a problem involving which of the following?

Plasma cells

Protein that forms the basis for blood clotting

Plasminogen

Fragment of megakaryocyte; provides basis for coagulation to occur; maintains hemostasis; average lifespan is 10 days

Platelet (Thrombocyte)

What is the primary advantage of autologous transfusions?

Prevention of viral infections from another persons blood

Carries hemoglobin to provide oxygen to tissues; average lifespan is 120 days

RBC (Erythrocyte)

Elevated/decreased MCH count

Same as MCV

a significant increase in the number of band cells

Signs and symptoms of infection

The site of activity for macrophages

Spleen

Iron deficiency in the adult generally indicates blood loss what are the diagnostic tests?

Stool for occult blood CBC

Responsible for cell—mediated immunity; recognizes material as "foreign" (surveillance system)
