Community Health Nursing Practice Exam

The major mode of transmission for hepatitis B is through exposure to contaminated blood. Hepatitis B virus (HBV) is primarily spread through contact with infectious body fluids, particularly blood, which can occur through various means such as sharing needles, receiving infected blood products, or through sexual contact with an infected partner.

Understanding this transmission method is crucial for community health nursing, as it emphasizes the need for education on safe practices, such as avoiding needle sharing and promoting the use of barrier methods during sexual activity. This focus on blood exposure distinguishes hepatitis B transmission from other infectious diseases, like those transmitted via the oral-fecal route, airborne droplets, or contact with rodents, which are not associated with HBV transmission.

Recognizing these distinct transmission pathways helps in creating effective prevention strategies and community health initiatives to reduce the incidence of hepatitis B.
