Correct answer: C

For an exposure to HIV, post-exposure prophylaxis (PEP) needs to be instituted within 72 hours of the sharps injury. Expert medical advice from an S-100 prescriber or infectious disease specialist is required. HIV PEP should ideally be administered within 24-36 hours after exposure. (ICG p.82)
