Question: A client presents to the emergency department with flu-like symptoms. During data collection, the nurses note the client returned from vacation 3 weeks ago, had a blood transfusion 3 years ago, and the sclera appears yellow in color. After being diagnosed with Hepatitis A virus (HAV), the client states, "How could I have gotten hepatitis?" Which nursing response given is most accurate? "It may have happened if you were engaging in unprotected vaginal sex." "It may have happened when you received the blood transfusion 3 years ago." "It may have happened if the food handler in a restaurant had the virus." "It may have happened if you were exposed to toxic chemicals in your workplace."
