Rh factor
A patient has blood type B negative. Which of the following donor types is safest for transfusion?
can receive from B– and O– only
This type of hemolytic anemia occurs when the body produces antibodies that attack its own red blood cells.
What is autoimmune hemolytic anemia?
Blood type A can give blood to this other blood type.
What is AB?
What antibodies does a person with Blood type A have in their plasma
What is B.
These two classic symptoms result from the breakdown of hemoglobin during hemolysis.
What are jaundice and dark urine?
The universal donor is this blood type.
What is O?
A person with A– blood can donate to someone with:
A– can donate to AB+ (because A and Rh antigens are present in AB+)
This blood test is typically positive in immune-mediated hemolytic anemia and helps confirm the diagnosis.
What is the direct Coombs test (direct antiglobulin test)?
These three blood types can donate blood to a person with blood type AB.
What is blood type A, B, and O?
A 24-year-old Rh-negative woman is pregnant for the first time. Her partner is Rh-positive. The baby is also Rh-positive. What is the next stop to prevent reaction?
The mother should receive Rhogam to prevent sensitization
What part of foreign substances do antibodies attack? This triggers the immune system, which makes the antibodies attack the substance.
What is an antigen?
This X-linked genetic disorder causes red cells to break down in response to oxidative stress, such as after eating fava beans.
What is G6PD deficiency?
Why can people with A blood not be able to donate to a person with B blood? (This is the term for the non-compatible reaction)
What is AGGLUTINATION.
A 28-year-old Rh-negative woman gives birth to her first child, who is Rh-positive. She did not receive Rh immunoglobulin (Rhogam) after delivery. During her second pregnancy with another Rh-positive baby, doctors detect fetal anemia. What is the most likely cause of the fetal anemia?
Maternal anti-Rh antibodies are crossing the placenta and destroying fetal red blood cells
A 62-year-old woman is admitted for elective hip replacement surgery. Her blood type is A negative. Pre-surgery labs are normal. Due to intraoperative bleeding, she is given two units of O positive red blood cells. Thirty minutes into the second unit, she develops fever, chills, chest pain, and dark-colored urine. Her blood pressure drops, and her heart rate rises.What is the most likely diagnosis?
Hemolytic transfusion reaction
A 40-year-old male with a history of chronic alcoholism presents with splenomegaly, jaundice, and fatigue. Lab results show an elevated reticulocyte count, spherocytes on the blood smear, and a positive osmotic fragility test.
What is hereditary spherocytosis?
Why can a person with blood type AB+ receive red blood cells from any blood type?
no antibodies against A, B, or Rh antigens
