Platelet deficiency resulting in spontaneous bleeding from small blood vessels.
Which of the following is FALSE regarding the role of platelets in hemostatic reactions?

Type O blood can safely be given to recipients with type B blood.
Why was Mr. Watkins given PRBCs in addition to normal saline solution? What problem does the infusion of PRBCs address that the saline solution could not?

agglutination
Which of the following is NOT a formed element in whole blood?
albunim
During erythroblastosis fetalis, a Rh− mother's anti-Rh antibodies that have crossed the placenta will cause agglutination of the fetus's Rh+ RBCs. However, the reverse problem never happens when a Rh+ mother is pregnant with a Rh− fetus; that is, antibodies produced by the fetus cannot cause agglutination of the mother's Rh+ RBCs. This is true because ______.
antibodies that can cause this agglutination are not produced by a fetus

eosinophil
which blood cell is higlighted
eosinophil
People with Type AB blood are considered "universal recipients" because they lack agglutinogens on their RBCs.
