Q

Your patient is complaining of chills and a fever. You suspect a transfusion reaction. What will be your actions

A

Stop the transfusion, start normal saline, VS’s and call the doctor.
. Be sure to mention disconnecting blood right at IV site so no more goes in – problem with nexiva catheters though! It mentions that with severe reactions with less than 10 mls of blood can occur! (“only a few mls”)

Q

What are the steps you would take after a transfusion reaction occurs and patient has been stabilized

A

You would recheck all the labelling, ID on patient etc., inform the blood bank, notify physician (should have already anyway!), keep the blood component/product to send to the blood bank for analysis, blood cultures if it’s a suspected infection and fill out all documentation forms per policy of the institution

Q

pts who have ITP immune thrombocytopenia purpura should they get platelets

what blood product hsould they receive
who else might need this

A

patients with idiopathic thrombocytopenia purpura (ITP) should not receive platelet transfusions unless bleeding is significant or life threatening. Platelet transfusion given to clients with ITP will be rapidly removed from circulation by the client’s anti-platelet antibodies and thus will be, at most, only of transient benefit

IVIG - human immunoglobulins replacement for treatment of some auto immune diseases (chronic fatigue syndrome), treatment for Kawasaki’s in pediatrics, Guillian-Barre, idiopathic thrombocytopenia purpura.

Q

what is fresh frozen plasma and how long can it be kept

indications for use FFP

A

Fresh Frozen Plasma is unconcentrated form of blood plasma containing all of the clotting factors except platelets.
Stored at minus 18 degrees Celsius or lower for up to one year.

FFP is indicated for:
 massive transfusion (replacement of the patient’s blood volume in < 24 hours) with deficiency of Factor VIII and V, otherwise frozen plasma is adequate. 
-exchange transfusion in neonates.

Q

what is cryoprecipitate and when is it indicated

A

Cryoprecipitate – is a low purity concentrate of 3 hemostatic proteins prepared from donated whole blood. A single bag of Cryo contains an average of 100units of factor VIII and von Willebrand factor, and 150-200mg of fibrinogen with some factor XIII and fibronectin. Made from plasma, fibrinogen and factors 8 and 13

for patients bleeding with low fibrinogen levels.

Q

what might these pts need

Kawasaki’s in pediatrics, Guillian-Barre, idiopathic thrombocytopenia purpura.

A

IVIG

28
Q

what are packed RBCS and who are they indiated for

A

RBCs that have been filtered and WBCs removed

Component of choice for virtually all patients with a deficit of oxygen carrying capacity, e.g. blood loss or anemia

29
Q

why are packed RBCs a good choice for bone marrow or organ transplant pts

A

The majority of the WBC are removed thereby decreasing the risk of cytomegalovirus (CMV) infection (CMV virus is carried in the WBC.)

also reduces the risk of the patient forming antibodies against WBC (HLA) antigens

30
Q

what properties does plasma have

A

oncotic and volume expanding

31
Q

functions of albumin

A

Maintains plasma colloid osmotic pressure and serves as carrier of intermediate metabolites in transport and exchange of tissue products.

32
Q

indications of albumin

A

Symptomatic relief and supportive treatment in management of shock, burns, hypoprothrombinemia, adult respiratory distress syndrome, cardiopulmonary bypass, acute liver failure, acute nephrosis, sequestration of protein-rich fluids, erythrocyte resuspension, hypotension or shock during renal dialysis, hyperbilirubinemia and erythroblastosis fetalis.

33
Q

are platelets generally cross matched

A

only if the platelet bag contains a lot of RBCs

the bag will contain all the same ABO type blood but wont nec be the same ABO as the recipient

34
Q

how long do platelets take before they expire

A

4hrs

35
Q

how are platelets and cryoprecipitate different

which to use if fluid vol restrictions

A

cryoprecipitate has some of the prenatant platelets removed so it is smaller vol and better for heart failure etc

36
Q

who is the universal recipient

universal donor

A

Type AB means both antigens are present- Neither antibody so * Universal recipient- can receive all blood types

Type 0 means neither antigen is present- Both A & B antibodies present: Can only receive type O Blood

37
Q

which of the following blood products MUST have ABO compatability

PRBC
Cryoprecipitate AHF (anti-hemophilic factor)
Platelets
Albumin (however, RH compatibility preferred)
IVIG
Rhogam
whole blood

A

PRBC and whole blood are the only two that require ABO compatibility.

38
Q

when would there be risk of hemolytic disease of the newborn

would it be with the first pregnancy

A

Rh neg mom and Rh pos baby. The moms Abs can get into the babies blood and cause hemolytsis

not problematic for first baby but each subsequent pregnancy the risk and dose of antibodies increases and so therefore does the (risk and severity of) hemolytic disease

39
Q

if baby is Rh positive and mum is Rh neg will she need rhogam
when would she get it

A

Mother needs Rhogam shot at 28 weeks gestation then within 72 hrs of the delivery.

40
Q

indications for rhogam

A
  • Pregnancy/delivery of an Rh-positive baby irrespective of the ABO groups of the mother and baby
  • Abortion/threatened abortion at any stage of gestation
  • Ectopic pregnancy
  • Antepartum fetal-maternal hemorrhage (suspected or proven) resulting from antepartum hemorrhage (e.g., placenta previa), amniocentesis, chorionic villus sampling, percutaneous umbilical blood sampling, other obstetrical manipulative procedure (e.g., version) or abdominal trauma
  • Transfusion of Rh incompatible blood or blood products
41
Q

can you hang blood alone

A

no. two RNS necessary

42
Q

what kind of pt ID do you need

A

name
pt medical ID
DOB
one unique identifier

43
Q

when you are hanging the blood what do you need to know about it other than that it matches the pts name, that the bag looks good

A

Check blood group and Rh factor, blood lot/serial number,

44
Q

what is the leading cause of death from transfusion

what kind of transfusion is this more likely to occur with

A

TRALI (transfusion related acute lung injury) now the leading cause of death (5-14% CFR)

often seen with plasma components not RBC’s.

45
Q

what is TRALI

how does it manifest

A

TRALI is a syndrome of acute respiratory distress.

potentially fatal, idiosyncratic reaction. Plasma antibodies from donor’s plasma, that are present in the blood component stimulate the recipients WBCS; aggregates of WBCs form and occlude the microvasculature within the lungs.

Manifested as pulmonary edema that can occur 4 hrs+ post transfusion → fever, chills, acute resp distress, s/s of acute left sided heart failure. Signs and Symptoms: Fever, pulmonary edema, hypotension, chills occurring 4-6 hours after transfusion.

46
Q

other than TRALI what is another very serious complication of transfusions that can lead to death and why does it occur

A

ABO incompatibility is one of the most serious usually causing death

Most attributed to Human Error – Patient misidentified, sample error, wrong blood, transcription/admin error, storage problem

47
Q

why might a febrile nonhemolytic reaction occur

A

Febrile non-hemolytic – reaction to cytokines, leukocytes, plasma antibodies, bacteria

48
Q

what is TACO

what are the manifestations

A

TACO (Transfusion Associated Circulatory Overload) – hypervolemia can develop = dyspnea, orthopnea, tachycardia, sudden anxiety, JVD, crackles at base of lungs, increased BP, possibly leading to pulmonary edema.

49
Q

who is at risk of transfusion assoc circulatory overload

A

Note…caution when transfusion given to client with CVD/Heart Failure/COPD.

50
Q

what would cause acute hemolysis

A

Acute hemolysis – wrong ABO group given to recipient.

51
Q

what IV gauges can you run blood through. why?

what can be done if the pt is pediatric or elderly and you cant get those gauges in

A

18 or 20 because of the rate of infusion

But you can infuse into a 22 g. For pediatric patients or elderly when only a smaller gauge will work, you can contact the lab and get the unit split into two so that it doesn’t need to infuse so fast.

52
Q

when infusing blood what other eqpt do you need?

what is the exception to this?

A

a primed bag of NS ready to go in case of reaction

53
Q

how do the rates for infusion of blood typically go

A

Rate of transfusion- not too fast for first 15 minutes as most likely time for reaction- 2ml/min or 20 gtt/min (10 drop factor for blood giving set) or @ 50ml/hr for the first 15 minutes for adults [PEDS: 1 mL/kg/hr x 15 min, then as ordered, probably 2-5 mL/kg]

54
Q

what are most blood products compatable with

what is the exception

A

NS in gen

IVIG only compatible with D5w

55
Q

when to do VS when giving blood

A

baseline,
immediately prior,
then at 5 minutes,
15 minutes and hourly until blood transfusion finished.

56
Q

what is the time limit that blood must infuse within and why

A

Blood needs to infuse within 4 hrs because it’s very good medium for bacterial growth.

57
Q

your pt has blood infusing but must go for a diagnostic what do you do

A

the pt cannot leave the unit with blood infusiing. postpone the diagnostic

58
Q

t or f flush with NS after giving blood

A

f

59
Q

after hangin blood and starting it is it ok to leave and attend to other pts?

A

no. most major reactions are more likely to occur in the first 15 minutes therefore nurse should stay and observe patient for at least 5 mins

60
Q

what VS should be reported if taking baseline vitals

A

if pt is febrile

61
Q

assessments to do before blood admin

A

Thorough head-to-toe assessment
Thorough medical history including transfusion history
Baseline lab work
Baseline vitals then Q5, Q15, q1h & monitor carefully
Report if patient febrile Prior to transfusion

62
Q

what lab work to do before blood admin

what lytes and why

A

Lab work – Hgb, Hematocrit, K, Cl, CBC, platelet count, INR possibly, PTT and other clotting factors if this is an issue.

when blood is stored destroys RBCs releasing K from cells into plasma so if blood transfused too fast transient hyperkalemia occurs before K is reabsorbed. Ca is diminished transiently - especially in young kids and the elderly.

63
Q
