30
prior to a blood transfusion...
type and cross match blood, explain procedure, obtain informed consent (need written), adequate IV access with atleast 20 gauge, hospitla policy and procedure for blood transfusions (IV pump), must remain with patient for 15 min following transfusion and monitor vitals
31
patients who cannot receive blood transfusions
jehova witness; can do autologous procedure to remove own blood overtime and give blood back during procedure; can receive albumin to expand blood
32
types of blood cells
A-, A+, B-, B+, AB-, AB+, O-, O+
33
Complications of transufions
febrile, non-hemolytic reactions; hemolytic transfusion reaction (stop immediately); ABO incompatibility which is life threatening (STOP immediately); Rh incompatibility; Circulatory overload; septicemia; hyperkalemia; iron overload
34
febrile non-hemolytic reaction
caused by platelet antigen or leukocyte sensitivity; causes temp to rise, chills, headache, flushing, anxiety during or soon after transfusion; most common reaction; can premedicate with benadryl and antipyretics
35
acute hemolytic reaction
hot feeling along the vein during transfusion; fever, chills, jaundice, flank pain, constricting pain in chest, low back pain, headache, nausea, tachycardia, tachypnea, hypotension, hemoglobinuria, impending doom feeling; correlation between amount of blood transfused and chances of fatal reaction (>100mL is increased chance of fatality)
36
nursing management of acute hemolytic reaction
STOP immediately; maintain patent IV with NS; monitor/ maintain airway, VS, and U/O; urine analysis for Hgb determination; notify provider and blood bank; save blood, supplies, and labels to return to blood bank; fill out transfusion reaction form; follow hospital procedure
37
diseases that can be transfused via blood
most common is hepatitis B and C; HIV and HTLV; CMV (highest risk for newborns/preemies)
38
circulatory overload transfusion reaction
infusion rate of transfusion is too fats or too much volume given
39
signs and symptoms of circulatory overload from transfusion; common in pt with HF; admin with diuretic because pt needs blood
cough, dyspnea, chest pain, rales, pulmonary edema, headache, HTN, tachycardia, rapid bounding pulse, distended neck veins
40
nursing interventions for reaction overload
decrease rate of infusion, position upright with feet dependent, admin O2 and diuretics as ordered; if pt at risk then admin diuretics between units
41
septicemia from transufions
occurs with transfusion of blood contaminated with microorganisms
42
signs and symptoms of septicemia from blood transfusion

43
nursing interventions for suspected septicemia from blood transfusion
obtain blood cultures and cultures of blood bag; admin IV fluids, antibx, steroids, vasopressor
44

45
45
signs and symptoms of iron overload (chelation)

46
47
nursing interventions for iron overload
administer deferoxamine (desferal) IV or SQ to remove excess iron through the kidneys; urine will turn red and know to discontinue when urine returns to normal color
48
hyperkalemia from blood transfusions
RBCs are lysed and release potassium; stored blood releases potassium via hemolysis; the older the blood the greater chance of increasing potassium; check dates on units of blood; check serum potassium pre and post transfusion
49

55
nursing interventions for anemia
balance physical activity and rest to decrease fatigue; adequate nutrition and hydration to maintain nutrition; compliance with medications like iron; monitor VS and maintain adequate perfusion; supportive therapy with O2 and fluids; monitor for complications like HF, angina, parasthesia, confusion

59
meds for iron deficient anemia
PO- ferrous sulfate, ferrous gluconate, ferrous fumarate; if PO iron poorly absorbed the IV iron
60
sickle cell anemia
hemolytic anemia; shortened life of RBC due to hemolysis; sickle cell shaped that can block arteries and cause pain; cell sickles d/t giving up O2 and gets stuck in capillaries and does not allow O2 to pass
