Q

The [?] are applied to the specimen tubes before leaving the bedside to avoid labeling the wrong tube.

A

labels

22
Q

The AABB Standards states “Blood and blood components shall be transfused through a [?] that has a filter designed to retain particles potentially harmful to the recipient.”

A

sterile, pyrogen-free transfusion set

23
Q

Blood components are infused slowly for the first [?] while the patient is observed closely for signs of a transfusion reaction.

A

10 to 15 minutes

24
Q

The blood components should then be infused as quickly as tolerated or, at most, within [?].

A

4 hours

25
Q

In standard blood administration sets, the [?] filter removes gross clots and cellular debris.

A

150- to 260-µm

26
Q

A [?] must be used for transfusion of all blood components.

A

blood administration filter

27
Q

• The receipt, preparation, and issue of blood components is guided by [?] published and enforced by the FDA.

A

current good manufacturing practice (cGMP) regulations

28
Q

• Each blood product is prepared and stored to optimize its [?] at the time of transfusion.

A

purity and potency

29
Q

• Quality control parameters are set by the [?].

A

FDA and AABB

30
Q

Increases red cell mass and plasma volume

A

Whole blood

31
Q

Whole blood Often available only for autologous units
Red Blood Cells (RBCs),
Apheresis RBCs
Increase oxygen-carrying capacity in anemia, trauma, and surgery
Expiration varies with anticoagulant
Frozen/deglycerolized RBCs
Prolonged red cell storage for rare blood units and autologous storage
24-hour outdate following deglycerolization
Washed RBCs
Reduce plasma proteins to avoid allergic and anaphylactic reactions (IgA deficiency)
24-hour expiration following washing
Platelets and RBCs Leukocyte
Reduced
Avoid febrile nonhemolytic reactions and prevent HLA alloimmunization, reduce
CMV transmission
Prestorage filtration more effective in avoiding cytokines
Irradiated RBCs and Platelets
Prevent GVHD in
immunocompromised patients, HLA-matched platelets or transfusions from a blood relative
Irradiation decreases shelf life of RBCs to 28 days
Platelets, Pooled Platelets
Bleeding caused by thrombocytopenia or thrombocytopathy
Pooling reduces expiration to 4
hours
Apheresis Platelets
Bleeding caused by thrombocytopenia or thrombocytopathy
May be HLA matched with recipient in cases of refractoriness
FFP, PF24
Replace stable and labile coagulation factors
Used in surgeries, trauma, and some factor deficiencies
Cryoprecipitated AHF (CRYO)
Contains fibrinogen, factors XIII and VIII, and von Willebrand’s factor
Treatment of von Willebrand’s disease, fibrinogen deficiency, and hemophilia A
Apheresis Granulocytes
Neutropenia with infection, unresponsive to antibiotics
Contains RBCs, must be ABO compatible
