What is the most common reason for steam sterilization failure?

  1. Lack of steam contact with the instrument

  2. Excessive exposure to steam

  3. Use of a biological indicator

  4. Presence of external chemical indicators

The correct answer is: Lack of steam contact with the instrument

The most common reason for steam sterilization failure is the lack of steam contact with the instrument. This can occur if the instruments are not properly arranged or if there are obstructions that prevent steam from reaching all surfaces of the instruments. Without adequate steam contact, sterilization cannot occur effectively, leading to failure. Options B, C, and D are not the most common reasons for steam sterilization failure.
