A nurse is caring for a client with acute hepatitis B. Which nursing intervention should be the priority to prevent transmission of the virus to others?

Standard precautions and proper hand hygiene are essential for preventing transmission of hepatitis B virus to healthcare workers and other patients. Hepatitis B is a bloodborne pathogen that poses a serious transmission risk in healthcare settings. The priority nursing intervention to prevent transmission is implementing standard precautions and maintaining proper hand hygiene protocols. Standard precautions are the foundation of infection control and involve treating all body fluids, blood, and potentially infectious materials as if they contain bloodborne pathogens. For patients with hepatitis B, this requires wearing appropriate personal protective equipment (PPE) including gloves when handling body fluids, proper disposal of contaminated materials in biohazard containers, and meticulous hand hygiene before and after patient contact. The hepatitis B virus (HBV) is highly contagious and can survive outside the body for up to 7 days. It is transmitted through contact with infected blood and body fluids, making healthcare workers particularly vulnerable during procedures such as blood draws, intravenous line insertions, and wound care. A positive HBsAg (hepatitis B surface antigen) indicates active infection and high infectivity. Proper hand hygiene using alcohol-based hand sanitizer or soap and water for at least 20 seconds is crucial after patient contact. Healthcare facilities must also ensure proper cleaning and disinfection of equipment and surfaces using EPA-approved disinfectants effective against HBV. Antiviral medications (option 1) are important for treatment but focus on symptom management rather than preventing transmission. Fluid management (option 2) helps prevent dehydration but is not directly related to preventing transmission. Nutritional counseling (option 4) supports recovery but is not a priority in infection control. Therefore, preventing transmission through infection control measures is the priority to protect healthcare workers and other patients from this serious bloodborne infection.
