Final answer:
The correct ICD-10-PCS root operation term for administering a transfusion of whole blood is 'transfusion'. This is used when a substance is provided to the patient through an orifice, as in the administration of blood or blood products.
Step-by-step explanation:
The correct root operation term used in ICD-10-PCS for 'A transfusion of whole blood was administered to the patient' is B) transfusion. In ICD-10-PCS, the root operation 'transfusion' refers to putting in or on a substance that provides nutrition, fluids, or other substances through a natural or artificial orifice, typically in the cases where blood or blood products must be administered to the patient.
For instance, following a motor vehicle accident with multiple traumatic injuries causing severe bleeding, where the patient's condition is critical, the type of blood often transfused is O negative. This is because O negative blood is considered the universal donor type and can be given to patients of any blood type when there's no time for determining their blood type. As for the patient's blood draw for surgery, if anti-A antibody and anti-B antibody are added to the blood and both wells show agglutination, this indicates blood type AB, which is a normal response for individuals with this blood type.
