Monitor fluid/electrolyte balance
Evaluate serum calcium levels
Before transfusions-
Vital signs
More at risk for a reaction-
Fever symptoms
Incompletable blood products-
hemolytic transfusion reaction
Stop transfusion immediately and hook them to normal saline to
flush the blood out
Tylenol or Benadryl for
Mild Allergic reaction blood transfusion
Blood Transfusion Reaction Treatment
STOP the transfusion. Notify doctor
Keep IV line open with 0.9% normal saline.
Monitor vitals Q15min
Post-transfusion blood sample
Treat s/sx
Step 1 for Blood transfusion
Check blood pack for: Leaks, Discoloration, Clumping and Expiration date.
If there is any discrepancy do not transfuse
Step 2 for Blood transfusion
Ask the patient to tell you their full name and date of birth
Check information on the compatibility label on the component against the patients wristband
If there is any discrepancy do not transfuse
If you are interrupted stop and start the checking procedure again; do not leave the patient until the transfusion has commenced
Step 3 for Blood transfusion
Check that the correct compatibility label is attached to the blood bag. if there is any discrepancy do not transfuse.
There is a donation number and blood group
If the checks are satisfactory, complete the pink portion of the label before commencing transfusion
Step 4 for Blood transfusion
Commence the transfusion
Step 5 for Blood transfusion
Once the transfusion has started:
Peel off the completed pink portion and attach in the patient’s medical notes- remember to sign the prescription to say you have undertaken the patient ID checks.
Step 6 for Blood transfusion
Once the transfusion has started:
Sign and complete the blue “return to laboratory” portion of the label, tear off and place in the container provided for return to hospital transfusion laboratory
Check with RN
Blood transfusion
One at the start and during, stay w the patient for the first 15 mins
Blood transfusion
Match the blood. Full set of vitals. Check policies and procedures
Blood transfusion
Be present. Time consuming

Deficiency in iron
Iron Deficiency Anemia Pathophysiology
Due to malabsorption (GI surgery, Gastric bypass)
Iron Deficiency Anemia Pathophysiology
Body loses healthy RBC due to Poor consumption of iron nutrients= deficiency
Iron Deficiency Anemia Pathophysiology
Excessive blood loss due to dialysis
Iron Deficiency Anemia Pathophysiology
Childbearing year women have problems getting iron in their blood.
Iron Deficiency Anemia Pathophysiology
Lack of stomach acid cannot absorb iron
Iron Deficiency Anemia Pathophysiology
Indigestion of Lead, Iron and lead compete for the cells in the body. Competition. Can get lead from water.
Iron Deficiency Anemia Pathophysiology
