Final answer:
The item not required on the donor tag after compatibility testing is the Recipient's name, as this tag needs to include information relevant to the blood unit's safety and compatibility, such as the donor's blood type, expiry date, and collection date. The option (A) is correct.
Step-by-step explanation:
The item that is not a requirement to be included on the donor tag once the appropriate compatibility testing has been completed and the unit is deemed suitable for transfusion is the Recipient's name. This is because the donor tag is associated with the unit of blood and needs to display information that ensures its safety and compatibility for any recipient, not just an individual recipient. Necessary information typically includes the donor's blood type (A, B, AB, O, and Rh factor), the expiry date of the blood unit to indicate when it can be used, and the collection date to track the age of the blood unit.
The pretransfusion testing involves confirming that both the donor and recipient have compatible blood types, and if necessary, performing cross-match assays to ensure there are no antibodies in the recipient's serum that could react against the donor's red blood cells. Therefore, option (A) is correct.
