The accurate grouping of blood is very important when it comes to having a blood transfusion. If blood is given to a patient that has a blood type that is incompatible with the blood type of the blood that the patient receives, it can cause intravenous clumping in the patient's blood which can be fatal. The patient’s body can start producing antibodies that attack the antigens on the blood cells in the blood that was given to the patient, causing reaction and rejection.
For example, a patient who is blood group B has naturally occurring Anti-A antibodies in their blood plasma. If this (blood group B) patient receives blood group A red cells, the Anti-A antibodies in the plasma of the patient will cause the blood group A red cells to clump intravenously (within the veins), which is life threatening.
A. Age
Age is the best answer because it is easily determined and since there are stages of development, age can tell staff other things such as coordination level, ability and risk of getting hurt.
I'll go through the other answers briefly.
B. Intelligence. Intelligence is a fair enough answer, save for the fact that it is something that is not easy to determine quickly and hence, it would be difficult to determine each child's intelligence before they came into the daycare. Furthermore, intelligence or lack thereof does not necessarily mean that the child does not need as much supervision.
C. Previous training. This is not the correct answer because it is the previous training "of the children cared for." The children do not need to have previous training. It could work as an answer if it were in relation to the workers, not the children.
D. Coordination. Somewhat of a good answer. However, once again, coordination is not an easy determinant, and cannot always reliably predict how many staff should be with how many children.
The answer is A because when they are a adult
