Explanation
A. Reservoir: The reservoir is the place where a pathogen lives and multiplies, such as a human, animal, or environment. It is not how the pathogen enters a new host.
B. Susceptible host: The susceptible host is the individual who can potentially be infected by the pathogen. However, this term does not describe how the pathogen enters the host.
C. Portal of entry: The portal of entry is the correct term for the route by which a pathogen enters a new host, such as through the respiratory tract, gastrointestinal tract, or broken skin.
D. Mode of transmission: The mode of transmission refers to how the pathogen is spread from one host to another, such as through direct contact, airborne particles, or vectors. It does not describe how the pathogen enters the host.
Correct Answer is A
Explanation
A. Wrapping hinged instruments in the open, unlocked position: Hinged instruments should be wrapped in the open, unlocked position to ensure that steam can penetrate all surfaces for effective sterilization.
B. Allowing the temperature of the autoclave to reach 200° F before timing: The autoclave should reach the required temperature (typically 250°F or 121°C) for the appropriate amount of time for sterilization, not 200°F.
C. Using a ballpoint pen to label contents: It is not advisable to use a ballpoint pen for labeling sterilized items because ink might not withstand the autoclave's high temperatures. Permanent markers or labels that can endure high temperatures should be used.
D. Stacking wrapped packages tightly into the autoclave: Items should be arranged in a way that allows steam to circulate freely, so tightly stacking packages can hinder proper sterilization.
