Question

multiple choice question which of the following would cause trapped air in the chamber of the autoclave, rendering the load unsterile? deposits that form on the inner surfaces blocked lines or valves use of tap water solutions that have boiled over

Explanation:

To determine what causes trapped air in an autoclave (making the load unsterile), we analyze each option:

• "Deposits that form on the inner surfaces" usually affect heat transfer or cleaning, not air trapping.
• "Blocked lines or valves" can disrupt steam flow, leading to air not being properly displaced (trapped air).
• "Use of tap water" relates to mineral deposits, not direct air trapping.
• "Solutions that have boiled over" cause contamination or mess, not air trapping.

Blocked lines/valves hinder steam from reaching all areas, leaving air trapped.

Answer:

B. Blocked lines or valves
