CRNI Blood Transfusion 2

Question 1

Which blood type is considered the universal plasma donor?

Accepted Answer

Type AB negative

Answer

Type AB plasma is universal donor plasma because it contains no anti-A or anti-B antibodies, making it safe for all recipients.

Question 2

What is the recommended initial flow rate when beginning a blood transfusion for the first 15 minutes?

Accepted Answer

2 mL/minute or less

Answer

Blood transfusions should begin at 2 mL/minute or less for the first 15 minutes to allow early detection of transfusion reactions before a significant volume is infused.

Question 3

A patient's pre-transfusion type and screen reveals an unexpected antibody. What is the appropriate nursing action?

Accepted Answer

Notify the blood bank for antigen-negative compatible units

Answer

When unexpected antibodies are detected, the blood bank must identify the antibody and provide antigen-negative, crossmatch-compatible units to prevent hemolytic reactions.

Question 4

Which transfusion reaction typically occurs 5-10 days after the transfusion?

Accepted Answer

Delayed hemolytic transfusion reaction

Answer

Delayed hemolytic transfusion reactions occur 5-10 days post-transfusion due to an anamnestic antibody response to donor red cell antigens.

Question 5

What temperature should blood products be stored at in the blood bank prior to transfusion?

Accepted Answer

1-6 degrees C

Answer

Packed red blood cells must be stored at 1-6 degrees C in monitored blood bank refrigerators to maintain viability and prevent bacterial growth.
