Which blood type is considered the universal plasma donor?
Answer: Type AB negative
Type AB plasma is universal donor plasma because it contains no anti-A or anti-B antibodies, making it safe for all recipients.
What is the recommended initial flow rate when beginning a blood transfusion for the first 15 minutes?
Answer: 2 mL/minute or less
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.
A patient's pre-transfusion type and screen reveals an unexpected antibody. What is the appropriate nursing action?
Answer: Notify the blood bank for antigen-negative compatible units
When unexpected antibodies are detected, the blood bank must identify the antibody and provide antigen-negative, crossmatch-compatible units to prevent hemolytic reactions.
Which transfusion reaction typically occurs 5-10 days after the transfusion?
Answer: Delayed hemolytic transfusion reaction
Delayed hemolytic transfusion reactions occur 5-10 days post-transfusion due to an anamnestic antibody response to donor red cell antigens.
What temperature should blood products be stored at in the blood bank prior to transfusion?
Answer: 1-6 degrees C
Packed red blood cells must be stored at 1-6 degrees C in monitored blood bank refrigerators to maintain viability and prevent bacterial growth.
When should blood bank compatibility testing specimens be collected relative to transfusion?
Answer: Within 72 hours of the scheduled transfusion
Pre-transfusion specimens must be collected within 72 hours of the scheduled transfusion for patients who have been transfused or pregnant within the past 3 months.
