Final answer:
Assigning a patient care technician with a history of hepatitis B infection (option B) would not be an appropriate patient care assignment.
Step-by-step explanation:
In a facility that dialyzes Hep + patients, an inappropriate patient care assignment would be assigning a patient care technician with a history of hepatitis B infection (option B). Hepatitis B is transmitted through blood and other body fluids, so it is essential to prevent any potential sources of infection for the safety of other patients and healthcare workers.
A nurse who has received the hepatitis B vaccine (option A) would be appropriate as they are protected against the infection. Patient care technicians who have not been vaccinated for hepatitis B (option C) should also not be assigned to care for Hep + patients, as they are at risk of contracting and spreading the infection. A nurse with no history of hepatitis B infection or vaccination (option D) would also be an appropriate assignment.
