Following high-level disinfection of an endoscope, which of the following methods is acceptable to eliminate accumulation of the disinfectant within the scope?
  1. Check the endoscope for the appearance of moisture.
  2. Rinse the endoscope with tap water.
  3. Flush the endoscope with sterile water.
  4. Use a chemical drying agent, such as acetone, to remove excess disinfectant.
Explanation
Answer: C-To eliminate the accumulation of disinfectant within the endoscope, the nurse can flush the endoscope with sterile water. After high-level disinfecting, an endoscope may retain some of the disinfectant solution, because of its design. This can lead to chemical irritation for the patient when the scope is used during the surgical procedure. Flushing the endoscope with sterile water eliminates excess disinfection and does not expose the scope to potential organisms found in tap water.
