Instruments contaminated with blood must be

  • A.left to dry in air
  • B.sterilized before reuse
  • C.rinsed in warm water only
  • D.wiped with a dry cloth

Answer: B

Hepatitis B survives on surfaces for at least a week and is transmitted very efficiently by inoculation, so nothing short of sterilization is adequate for an instrument that will penetrate tissue. Cleaning alone leaves infectious virus behind.
