Questions & Step-by-Step Solutions

In a case study, a surgical instrument was found to be contaminated with Staphylococcus aureus. Which sterilization method would be most effective?
Correct Answer: Ethylene oxide gas
  • Step 1: Identify the problem - A surgical instrument is contaminated with Staphylococcus aureus, a type of bacteria.
  • Step 2: Understand sterilization - Sterilization is a process that kills all microorganisms, including bacteria.
  • Step 3: Consider the type of instrument - Determine if the instrument is heat-sensitive, meaning it cannot be exposed to high temperatures.
  • Step 4: Choose a sterilization method - For heat-sensitive instruments, ethylene oxide gas is a suitable option because it can effectively sterilize without heat.
  • Step 5: Confirm effectiveness - Ethylene oxide gas is known to eliminate Staphylococcus aureus and other harmful microorganisms.
  • Sterilization Methods – Understanding different sterilization techniques and their effectiveness against specific pathogens.
  • Microbial Contamination – Knowledge of common pathogens like Staphylococcus aureus and their resistance to various sterilization methods.
  • Heat-Sensitive Instruments – Recognizing which surgical instruments cannot withstand high temperatures and require alternative sterilization methods.
