A clinical medical assistant discovers a fire in the facility and is attempting to put out the fire using a fire extinguisher. Which of the following actions should the assistant take?
Aim the discharge at the top of the fire.
Move the extinguisher from side to side.
Shake the extinguisher before using.
Squeeze the handle before pulling the pin.
The Correct Answer is B
A. Aim the discharge at the top of the fire: The correct action is to aim at the base of the fire, not the top.
B. Move the extinguisher from side to side: This is the correct technique for using a fire extinguisher (PASS method: Pull, Aim, Squeeze, Sweep). Sweeping the extinguisher from side to side helps cover the area of the fire.
C. Shake the extinguisher before using: Shaking is not necessary and might not be recommended; instead, you should ensure the extinguisher is in working order.
D. Squeeze the handle before pulling the pin: The pin should be pulled first to unlock the extinguisher before squeezing the handle.

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.
