Which set of pathogens are listed as the three main bloodborne pathogens?

• A. HIV, HBV, HCV
• B. HIV, HBV, HPV
• C. HIV, HCV, TB
• D. HBV, HCV, MRSA

Answer: (A)

The main idea is identifying the primary bloodborne pathogens you must guard against in settings where exposure to blood or body fluids can occur. The three key pathogens are HIV, hepatitis B virus, and hepatitis C virus. They’re emphasized because transmission can occur through infected blood and certain body fluids, making occupational safety measures essential. HBV is especially notable as it is highly infectious and vaccine-preventable, while HIV and HCV can lead to long-term health problems and require prompt exposure response and treatment. The other options don’t fit because HPV is not primarily transmitted through blood (it's usually sexually transmitted or through skin contact) and TB is spread through airborne droplets, not blood; MRSA is a skin and wound infection spread mainly by direct contact, not through blood.
