Final answer:
The hospital can prevent transfusion errors by requiring two-person verification processes to confirm the correct patient's identity before transfusion.
Step-by-step explanation:
The hospital must prevent transfusion errors by requiring verification of the correct patient using a two-person process when the order for the blood or blood product is confirmed. This means that two different individuals are involved in confirming the patient's identity before the transfusion takes place, reducing the risk of errors. By having two different people verify the patient's identity, the likelihood of mistaken identity is minimized.
