Compounding Exam -Solved
_____________ is the air exiting the HEPA filter in a unidirectional air stream that is
virtually free of contamination. - ANSWER-ANY OF THESE RESPONSES:
First air
1st air
_________________ pressure is used to separate the ISO Class 5 space in a primary
engineering control when the space is designed for nonhazardous compounding. The
answer is not case sensitive. - ANSWER-Positive
All of the following considerations specific to PECs used for compounding hazardous
drugs are valid EXCEPT which? - ANSWER-ISO Class 5 BSCs/CACIs do not have to
be vented to the outside.
All the following statements about using unidirectional airflow are correct EXCEPT for
which? - ANSWER-For first air to be used properly, only one item can be placed
between the HEPA filter and critical site.
From the list below, select the test that is NOT required during certification of PECs. -
ANSWER-Electrical conductivity
HEPA filters must be leak tested at which of the following occasions? More than one
answer is correct, so select all that apply. - ANSWER-Every six months for the life of its
use
At the factory
When it is placed (either in a PEC or room)
HEPA filters used in sterile compounding application must be at least ______________
efficient at the most penetrating particle size (MPPS) of ______________ microns. -
ANSWER-99.99%, 0.3
HEPA filters work to filter which of the following? - ANSWER-Particulates
In horizontal laminar airflow workbench (LAFW), materials need to be placed across the
work surface (from left to right) with nothing between the HEPA filter and the
components to make sure first air is not blocked. - ANSWER-True
Match the description of the direction of the airflow to the type of airflow. - ANSWER-Air
from the HEPA filter is blowing toward you - Horizontal Flow
