which of the following devices should a pharmacy technician use to transfer a large amount of fluid from one container to another?
○ syringe
○ pump

Explanation:

First Question (Air in Compounding Area)

In a compounding hood (like a laminar flow hood), the HEPA filter is responsible for filtering air to remove particles. Air near the HEPA filter (usually at the top/back, and the filtered air moves down) is the cleanest as it's freshly filtered. The other options (near sides, front, or just top without filter context) are incorrect—sides/front have more turbulence or unfiltered air interaction, and "near top" is vague (the HEPA filter is typically at the top to supply clean air downward).

A syringe is good for small, precise fluid transfers. A pump (like a peristaltic pump or transfer pump) is designed to move large volumes of fluid efficiently from one container to another. So for a large amount, a pump is the appropriate device.

Answer:

The cleanest air is near the HEPA filter.
