Final answer:
Recombinant factor IX practically eliminates the risk of infectious diseases when compared to plasma-derived factor IX, as it is created in a lab setting using DNA technology and minimizes the risk of viral contamination.
Step-by-step explanation:
The nurse should explain that recombinant factor IX practically eliminates the risk for infectious diseases, such as HIV and hepatitis, as compared to plasma-derived factor IX. Unlike plasma-derived products, which are obtained from human blood and carry a risk of transmitting diseases found in blood, recombinant factor IX is produced using DNA technology in a laboratory setting, significantly reducing the risk of contamination from human viruses. Patients using recombinant therapies therefore have a much lower risk of contracting diseases through their treatment.
