Assignment Problem: A young man named Clyde accompanies his girlfriend, Josie, to the emergency department. She has a deep laceration on her right arm and has lost a lot of blood. She is pale, cool and clammy to the touch. You think she may need a blood transfusion if the intravenous fluids do not restore her blood volume promptly and adequately. Clyde is adamant you take his blood and give it to Josie; he would do anything to save her. You will need to explain to him whether his blood type (AB) is a match for her blood type (O).
a. What will you tell Clyde? Be specific with your explanation why he can or cannot donate his blood to Josie.
b. Describe the role B-cells have during an immune response when an incompatible blood type is donated.
c. Which blood type is considered the universal recipient? Briefly explain.
d. Considering the blood loss Josie is experiencing, will vasopressin (AKA anti-diuretic hormone) be released in this situation? Briefly explain your response.
