    • 7-9

    • 9-10

    Correct Answer
    A. 7-9
    Explanation
    The pH of a cleaning solution should be between 7-9. This range is considered optimal for cleaning because it allows for effective removal of dirt and stains without causing damage to the surfaces being cleaned. Solutions with a pH below 7 are acidic and may be too harsh, while solutions with a pH above 9 are alkaline and may leave residue or cause discoloration. Therefore, a pH range of 7-9 strikes a balance between effectiveness and safety for most cleaning applications.

    What is the policy regarding the use of saline on surgical instruments for soaking?

    • The use of saline is acceptable as long as instrumentation is removed from the solution and rinsed within 10 minutes.

    • The use of saline is acceptable because the sodium will make it easier to remove blood, film, and proteins from the surface of the instrument. 

    • The use of saline is not acceptable because the sodium will cause blood and tissue to harden on the instruments.

    • The use of saline is not acceptable because it can damage the surface of the instrument. 

    Correct Answer
    A. The use of saline is not acceptable because it can damage the surface of the instrument. 
    Explanation
    The correct answer is that the use of saline is not acceptable because it can damage the surface of the instrument. Saline is a solution of sodium chloride, and the sodium can cause corrosion or pitting on the surface of the instrument. This can compromise the integrity of the instrument and make it less effective or even unsafe to use during surgery. It is important to use appropriate cleaning and sterilization methods for surgical instruments to ensure their safety and effectiveness.
