Aseptic technique is also known as:
A. Clean technique
B. Sterile technique
C. Sterilization
D. Decontamination - ANSWERS-A. Clean technique
Aseptic technique refers to clean methods of containing microbial contamination in the
environment. The environment cannot be sterilized.
An intrinsic factor that contributes to the development of a pressure injury is:
A. Pressure
B. Hypothermia
C. Diabetes mellitus
D. General anesthesia - ANSWERS-C. Diabetes mellitus
An intrinsic factor is related to the health of the patient. Diabetes mellitus is an intrinsic factor
that contributes to the development of a pressure injury.
Which of the following helps determine a patient's discharge destination?
,A. Written discharge instructions from anesthesiology and medical staff
B. Risk of postoperative complications
C. Standardized pain scoring
D. General condition and readiness for discharge - ANSWERS-B. Risk of postoperative
complications
The choice of discharge site is based on patient acuity, access to follow-up care, and the
potential for postoperative complications.
Central nervous system (CNS) signs and symptoms of local anesthetic systemic toxicity (LAST)
include:
A. Hypertension
B. Numbness of lips and tongue
C. Respiratory depression
D. Elevated temperature - ANSWERS-B. Numbness of lips and tongue
CNS symptoms of LAST include circumoral and tongue numbness. All other options are not
considered part of the CNS.
Autologous bone grafts should be stored at a temperature of:
A. 68*F (20*C)
B. 32*F (0*C)
C. -4*F (-20*C)
D. -112*F (-80*C) - ANSWERS-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.
When providing patient education for a child, it is important to understand which learning
characteristics of children?
A. Children are self-directed
B. Children use intrinsic thought processes
C. Children respond to use of activities that follow transitions of maturity.
D. Children respond to a trial-and-error approach - ANSWERS-D. Children respond to a trial-and-
error approach
When teaching children, using a trial-and-error approach is effective. Child learners are task-
oriented, use extrinsic thought processes, and value self-esteem.
Which of the following actions would decrease radiation 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 - ANSWERS-D. Positioning
the patient as close to the image intensifier as possible
The x-ray beams originate from the tube and are captured by 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 - ANSWERS-
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.
A diagnostic procedure that replies on radio-frequency waves 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 - ANSWERS-D. Magnetic resonance imaging
Magnetic resonance imaging stimulates disequilibrium in the nuclei of hydrogen atoms and the
water of body cells. As nuclei return to their original state, they emit radiofrequency signals.
Which of the following movements of a powered instrument is used to drill holes or to insert
screws, wires, and pins?
