Question

which of the following are causes of low temperature in an autoclave?

□ opening the unit too wide during drying

□ not running a sufficient amount of items in the load

□ overfilling the water reservoir

□ underfilling the water reservoir

□ failure to preheat the autoclave chamber

Explanation:

• Not running a sufficient amount of items in the load: Less items mean less heat retention and distribution issues, leading to lower temperature.
• Underfilling the water reservoir: Insufficient water means less steam production, which is needed for high temperature in autoclave, so temperature stays low.
• Failure to preheat the autoclave chamber: If the chamber isn't preheated, it starts from a lower temperature, affecting the overall temperature during operation.
• Opening the unit too wide during drying affects drying, not temperature during sterilization (autoclave's main temp - related phase is sterilization, not drying for temp drop here).
• Overfilling the water reservoir would not cause low temp; excess water might not reduce temp production (steam - related), so it's not a cause.

Answer:

B. Not running a sufficient amount of items in the load, D. Underfilling the water reservoir, E. Failure to preheat the autoclave chamber
