Correct answer: B

After a sharps injury with HIV-infected blood: 0.3% risk of seroconversion. After a mucous membrane exposure to HIV-infected blood: 0.09%. The mucous membrane exposure risk is lower than the percutaneous (sharps) risk. Only a very small proportion of occupational exposures to HIV result in transmission. (ICG p.84)

Remy's study tip — The differentiator is usually the Spaulding classification level or the step order in a protocol.
