Answer :
Final answer:
The determination for administering adult or pediatric CPR is based on the victim's age, with adult CPR given to those roughly 12 years or older and pediatric CPR to younger children. In emergency situations with no time to test for blood type, O negative blood is transfused as it is the universal donor. A normal agglutination reaction with both anti-A and anti-B antibodies indicates a patient has type AB blood.
Explanation:
What determines whether a victim should receive adult or pediatric CPR is primarily determined by the age of the victim. For individuals who are considered adults, usually those who are adolescents (about 12 years or older) or older, adult CPR is administered. For children younger than roughly 12 years of age and infants, pediatric CPR, which involves different techniques, is used.
In the scenario where a patient following a motor vehicle accident is rushed to the emergency department with severe bleeding and in critical condition, there is no time to determine their blood type. In such urgent situations, O negative blood is usually transfused because it is considered the universal donor type and is compatible with all other blood types, minimizing the risk of a transfusion reaction.
Regarding the blood typing procedure, if both the anti-A and anti-B antibodies cause agglutination in the patient's blood, this indicates that the patient has type AB blood, which is a normal response. Therefore, no error has been made by the technician. Type AB blood contains both A and B antigens on the surface of the red cells; hence it reacts with both types of antibodies.
