Which of the following is listed as a method of reducing exposure?

• A. Keep evidence in plastic bags
• B. Vaccine for Hep B
• C. Inspect personal bags with gloves
• D. TB precaution

Answer: (B)

Vaccination is a proactive way to reduce exposure risk by preventing infection before it can happen. Getting the Hepatitis B vaccine gives the body immunity to HBV, so even if an exposure occurs, the chance of becoming infected is greatly lowered. The other items address handling or protective practices but don't reduce the risk of infection as directly or effectively as immunization does: storing evidence in plastic bags is about containment and preservation, inspecting personal bags with gloves is a protective procedure, and TB precautions are important safety measures but do not provide immunity. Vaccination directly lowers the likelihood of disease, making it the best choice.
