Exam 1 Flashcards
What are nursing implications for the administration of all blood components, including donation, processing, and administration, and complications?
DONATION
American Red Cross donation requirements
Type and Cross
A, B, O, AB
Rh+ & Rh –
FFP requires ABO but not Rh compatibility
Platelets are not typically cross-matched for ABO compatibility
Testing
Autologous donation
Intraoperative blood salvage- cannot be stored
TRANSFUSION
Blood Administration
Only with NS, Never medications or other fluids through blood tubing
Never medications or other fluids through blood tubing
Only through appropriate filter tubing, change tubing after 2 units (check hospital policy)
Administration time per unit should not exceed 3 ½ hours
Platelets or FFP:
Infuse each unit over 30-60 minutes
FFP requires ABO but not Rh compatibility testing
Platelets typically not cross-matched
steps:
verify Dr order- hgb of 10- anemic, below 8- needs blood transfusion
Obtain consent
Assess IV site & patency
Obtain blood from blood bank
Check accuracy of blood label and pts ID
Baseline VS & assessment
Start the infusion
VS & assessment recheck
Monitor transfusion reactions
complications: occurs in the first 10-15 minutes or first 50cc of blood
Febrile nonhemolytic reaction- chills, fever, HA, flushing tachycardia, anxiety
Acute hemolytic reaction- low back pain, hypotension, tachycardia, fever & chills, chest pain, tachypnea, hemoglobinuria, can be immediate
Allergic reaction- hives, pruritus, facial flushing, SOA, brochospasm, anxiety
Circulation overload-
Bacterial contamination-
Disease acquisition- Hepatitis, AIDS
implications
stop transfusion (maintain line with normal NS) & notify DR
change IV tubing
treat symptoms
recheck crossmatch record with unit
hemolytic reactions-
obtain 2 blood samples distal to infusion site
obtain first UA- test for hemoglobinuria
monitor F & E
serum calcium levels
bleeding disorders
Thrombocythemia- high platelet count resulting from stem cell disorder within BM
Thrombocytopenia- low platelet due to decreased production in BM, increased destruction and increased consumption
Immune Thrombocytopenic Purpura (ITP)- a decreased number of circulating platelets manifests as a bleeding tendency, easy bruising (purpura), or extravasation of blood from capillaries into skin and mucous membranes (petechiae).
Acquired Coagulation Disorders- including vitamin K deficiency and warfarin therapy, liver disease, Disseminated Intravascular Coagulation, platelet disorders and vascular disorders

Atrial flutter
Chest pain, SOA, hypotension
Ventricular tachycardia (V. tach) Nearly always unresponsive/pulseless
Ventricular fibrillation (V. fib)
Absence of audible heartbeat
No palpable pulse
No respirations
Medical management/Medications- rhythm disturbances
Atrial fibrillation
Anticoagulants/antiplatelets, Class II and IV antiarrhythmics; Pharmacologic cardioversion
Electrical cardioversion, catheter ablation therapy, Maze/Mini-Maze Procedures
blood pools in atrial, beta blockers & calcium channel blockers (rate control),
Inititate anticoagulants prior to restoring sinus rhythm
Atrial flutter
Adenosine
Antithrombotic drugs, rate and rhythm control similar to atrial fibrillation
Electrical cardioversion
Ventricular Tachycardia
Immediate defibrillation for pulseless VT!
CPR
Cardioversion, antiarrhythmic medications, antitachycardia pacing
ICD
Catheter ablation
Torsades de pointes: polymorphic, prolonged QT interval
Correct magnesium imbalance
Ventricular fibrillation
CPR
Defibrillation
Amiodarone, epinephrine
Defibrillate v fib and v flutter
Assess pt
Call code
Initiate cpr
Sinus brady- not a big deal unless they have symtoms
A fib- blood pools- anticoagulants first
A flutter- rare, same as a fib
Most Important lab values for CAD
Total Cholesterol <200 mg/dL
LDL (bad) Cholesterol <100 mg/dL
HDL (good) Cholesterol > 40 mg/dL (males) >50 mg/dL (females)
Triglycerides <150 mg/dL
increased = increased risk for coronary artery disease
