The most appropriate laboratory test for early detection of acute hemolysis is

A patient received 2 units of packed RBCs and had a delayed transfusion reaction. Antibody screening records indicate that no agglutination was detected during testing except after addition of IgG sensitized cells (check cells. Repeat testing of the pre-transfusion specimen detected an antibody at the antiglobulin phase. What is a possible explanation?

Platelets are made from a unit of whole blood in the following way:

The criteria for autologous donation is the same as for allogenic donation

With the exception of frequency of donation, the criteria for apheresis donation is the same as for allogenic donation.

Which of the following tests are NOT performed routinely on a donor unit of blood?

Autologous units can be stored with allogenic units as long as the label indicates “for autologous use only.”

What is the benefit of using leuko-reduced RBCs?

What is the benefit of apheresis platelet collection?

A unit of RBCs is issued at 9:00 am. At 9:10 am, the unit is returned to the Blood Bank. The container has NOT been entered, and has been refrigerated at 1-6 degrees C during this time span. The best course of action for the technician is to

If the seal is entered on a unit of packed cells stored at 1-6 degrees C, what is the maximum allowable storage period, in hours?

Which of the following blood components is the best source of fibrinogen for transfusion to a patient with hypofibrinogenemia?

A patient has had massive trauma involving replacement of one blood volume with packed cells and volume expanders. She is currently experiencing oozing from mucous membranes and surgical incisions. Laboratory values are as follows: PT: Normal APTT: Normal Bleeding Time: Prolonged Platelet count: 20 x 10 to the 3rd/ul Hemoglobin: 11.4 g/dl What is the component of choice for this patient?

The most important step in the safe administration of blood is to

Which of the following is consistent with standard blood bank procedure governing the infusion of fresh frozen plasma?

A patient who is group AB, Rh- negative needs 2 units of fresh frozen plasma. Which of the following units of plasma would be MOST acceptable for transfusion?

Fresh frozen plasma from an A Pos donor may be safely transfused to a patient who is

A patient admitted to the trauma unit requires emergency release of fresh frozen plasma (FFP. His blood donor card states that he is AB Pos. Which of the following blood groups of FFP should be issued?

A 22 year old man is admitted to the ER in shock following massive hemorrhage from knife wounds to his chest and abdomen. An emergency transfusion is required. Which of the following is the product of choice?

A 29 year old male is hemorrhaging serverely. He is AB Neg. Six units of blood are required STAT. Of the following types available in the blood bank, which would be most preferable for a crossmatch?

AHG reagents, blood typing reagents and antibody screening reagents must be tested each week with QC solutions and cells.

IgG sensitized cells in antiglobulin procedures serve as a QC check on reagent and procedure.

Refrigerators, freezers, heating blocks, water baths must undergo daily temperature checks.

Serofuges/cell washers must have timers and speed regularly check
