MULTIPLE CHOICE
1. All of the following situations would require aseptic techniques EXCEPT .
a. barium enema examination.
the following situations would require aseptic techniques are .
b. insertion of central venous line.
c. insertion of an indwelling Foley catheter.
d. insertion of an angiographic catheter.
Among the numerous imaging procedures that require sterile technique are angiography and
line placements, indwelling urinary catheters, arthrography, hysterosalpingography, and
biopsies. Barium enema examinations are not considered sterile procedures.
2. The goal of aseptic technique is to.
b. protect the patient from pathogenic microbes.
The goal of aseptic technique is to protect the patient from pathogenic microbes.
The goals of aseptic technique are to protect the patient from infection and to prevent the
spread of pathogenic microorganisms.
3. When creating a sterile field, it is important for the imaging professional to .
c. keep sterile gloves in sight and above the waist level.
When creating a sterile field, it is important for the imaging professional to keep
sterile gloves in sight and above the waist level.
A sterile field is a specified area that is considered free of viable microorganisms. It is
regarded to be everything above waist level.
4. When establishing a sterile field using a sterile drape, .
b. all drape items must be clean and dry.
When establishing a sterile field using a sterile drape, all drape items must be clean
and dry.
, In most instances, a sterile field is established using a sterile drape. The first step in using a
sterile drape is confirming that the package is sterile. If a package is not clean and dry, it is
considered unsterile. If it appears to have been previously opened or if the expiration date
has passed, it is also considered unsterile. It is not acceptable to reach over any sterile field.
5. When opening and pouring sterile solutions .
d. hold the bottle with the label facing up to prevent fluids from staining the label.
When opening and pouring sterile solutions, hold the bottle with the label facing up
to prevent fluids from staining the label.
Sterile solutions are frequently poured into a metal or other container within the sterile field.
Begin with verifying the contents and expiration date on the solution. When possible, show
the name to another health care person for verification. Remove the lid or cap from the
bottle and place it on an unsterile surface. Hold the bottle with the label uppermost so that
poured solution cannot stain and obscure the label. With as little of the bottle as possible
over the field, hold it at a height of approximately 1 to 2 inches over the bowl so that no
splashing occurs.
6. The inflatable balloon portion of the Foley catheter is typically filled with .
c. sterile water.
The inflatable balloon portion of the Foley catheter is typically filled with
sterile water.
On insertion of the Foley catheter, the balloon is filled with sterile water to hold the catheter
in place.
7. Which of the following statements are true ? all of these .
a. A sterile person may touch only what is sterile.
c. A sterile field must be watched continually to be considered sterile.
d. If a solution soaks through a sterile field to a nonsterile field, the wet area must be
redraped.
The goals of aseptic technique are to protect the patient from infection and to prevent the
spread of pathogens and harmful microorganisms. Sterile fields should be created no sooner
than the needed procedure time to prevent transient contamination as a function of time
delays.
