Which of the following is reshaped during a total hip arthroplasty?
A. fibula
B. acetabulum
C. iliac crest
D. tibia - correct answer B. The acetabulum is deepened during a total hip
arthroplasty.
An organization that regulates the production of biological sterilization test
packs in-house is
A. CDC.
B. ANSI.
C. AAMI.
D. SDS. - correct answer C. Association for the Advancement of Medical
Instrumentation (AAMI) controls regulation of sterile processing.
Rod-shaped bacteria are called
A. bacilli.
B. cocci.
C. vibrio.
D. spirals. - correct answer A. Rod-shaped bacteria are called bacilli. They
can be slightly curved or straight. Bacillus is Latin for "stick."
,A type of passive transport when salt crystals dissolve in water is known as
A. phagocytosis.
B. endocytosis.
C. osmosis.
D. diffusion. - correct answer D. Diffusion is simple movement of particles
within a solution. When the salt is added to water, the molecules simply
disperse within the solution.
Utilization of lasers in the operating room requires the use of
A. a HEPA filter mask.
B. a lead apron.
C. double gloves.
D. eye protection. - correct answer D. The eye is the organ most
susceptible to laser injury. A specific type of safety glasses is required for
each type of laser unless amber lenses are worn.
During application of a Volar splint, the surgical technologist notices that the
splint was not completely dried and has caused a pressure point on the
patient. Which of the following should be the surgical technologist's NEXT
step?
A. Allow the splint to remain as-is and allow more time to dry.
B. Notify the nurse and let the nurse handle it.
C. Bring it to the surgeon's attention and assist in putting on a new splint.
D. Apply a new splint and notify the surgeon when finished. - correct answer
C. The surgeon is responsible for the splint that he just custom-made for the
,patient. Pressure points can cause blistering and pain and sometimes impede
wound healing if ignored.
Sponges that have been added to the sterile field after a procedure has begun
should be counted by the
A. circulator and surgeon.
B. surgical technologist and surgical first assistant.
C. surgeon and surgical first assistant.
D. surgical technologist and the circulator. - correct answer D. Both the
surgical technologist in the scrub role and the circulator must participate in the
count according to typical hospital policy.
Which of the following spore-forming microorganisms are used as biological
monitors for checking steam sterilization effectiveness for a load of
instruments in a rigid container?
A. Bacillus stearothermophilus
B. Bacillus atrophaeus
C. Mycobacterium tuberculosis
D. Streptococcus pyogenes - correct answer A. Bacillus
stearothermophilus, a highly heat-resistant, spore-forming microorganism that
does not produce toxins and is non-pathogenic, is used as the biological
monitor for steam sterilization.
After surgery, the scrub tech takes the instruments used in surgery to the
decontamination area. How soon should these instruments be washed?
A. within 20 minutes
, B. within 10 minutes
C. as soon as they arrive to the decontamination area
D. any time the technologist is available - correct answer A. Ideally,
instruments should be washed within 20 minutes to prevent blood, tissue, and
biofilm from drying on the surfaces, as it can be difficult to remove and can
impede sterilization.
Which of the following types of laser is typically used for stone fragmentation
in the ureter?
A. argon
B. krypton
C. carbon dioxide
D. holmium: YAG - correct answer D. Holmium: YAG is used to fragment
stones in the ureter.
If a patient is undergoing a mastectomy immediately followed by
reconstruction, how many surgical setups should be obtained?
A. One; the reconstruction will immediately follow the mastectomy, so the
same instruments can be used without additional interventions.
B. One; the reconstruction will immediately follow the mastectomy, so the
same instruments can be used after they are cleaned with sterile water.
C. Two; the reconstruction will immediately follow the mastectomy, but a
second set of instruments should be used to prevent seeding.
D. Two; the reconstruction will immediately follow the mastectomy, but it will
be done in a different OR so two sets are needed. - correct answer C. Even
though the reconstruction will follow immediately behind the mastectomy, a
second set of instruments should be used to prevent seeding (spread of
cancer cells).
