Explanation below
Step-by-step explanation:
There are different form or type of blood group. These include blood group A, B, AB and O.
The blood group AB is usually known as the universal recipient while the blood group O is the universal donor.
A universal donor can donate blood to all other blood groups, while the Universal recipient can receive blood from all other blood groups.
In this case, two patients, one with blood group A and the other with blood group AB, with only one available group A type pint for transfusion. The best thing to do in this case is to give the blood to group A patient and get any other blood group pint of blood for the group AB patient. This is because the blood group AB patient can receive blood from any of the blood groups.
