B. 32*F (0*C)
C. -4*F (-20*C)
D. -112*F (-80*C) - CORRECT ANSWER-C. -4*F (-20*C)
Maintaining storage temperatures within recommended
parameters of -4*F (-20*C) helps ensure that autografts are
maintained in optimal conditions for successful replantation.

exposure during fluoroscopy procedures?
A. Positioning the patient as close to the tube as possible
B. Positioning the patient as far from the image intensifier as
possible
C. Positioning the patient as far from the monitor as possible
D. Positioning the patient as close to the image intensifier as
possible - CORRECT ANSWER-D. Positioning the patient as

the image intensifier. Multiple studies have demonstrated that
positioning the patient closer to the image intensifier results in a
significantly decreased dose of radiation.
A perioperative nurse is assisting an anesthesia professional
with a rapid-sequence induction by providing cricoid pressure
using the Sellick maneuver. Which of the following is the most
appropriate description of this technique?
A. Exerting down-and-up pressure on the cricoid cartilage to
compress the trachea
B. Palpating for the thyroid cartilage and exerting pressure on it
with a dominant index finger and thumb to occlude the
esophagus
C. Applying pressure on the cricoid cartilage to occlude the
esophagus
, D. Maintaining pressure on the thyroid cartilage until anesthesia
verifies placement - CORRECT ANSWER-C. Applying pressure
on the cricoid cartilage to occlude the esophagus
The Sellick maneuver, more commonly known as cricoid
pressure application, involves exerting downward pressure on
the cricoid cartilage with the thumb and index finger of one
hand to compress the esophagus. The Sellick maneuver is
used to prevent potential aspiration during induction of
anesthesia.

to reproduce cross-sectional images of the body without
exposing the patient to ionizing radiation is:
A. Ultrasonography
B. Position emission tomography
C. Computed tomography
D. Magnetic resonance imaging - CORRECT ANSWER-D.
Magnetic resonance imaging
Magnetic resonance imaging stimulates disequilibrium in the
