CNOR Practice Exam 100 Questions with Verified
Answers.
Aseptic technique is also known as:
A. Clean technique
B. Sterile technique
C. Sterilization
D. Decontamination - Correct Answer 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 - Correct Answer 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 - Correct Answer 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 - Correct Answer 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) - 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.
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 - Correct Answer 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 - Correct Answer
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 -
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.
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 - Correct Answer 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?
A. Reciprocating
B. Oscillating
C. Alternating
D. Rotating - Correct Answer D. Rotating
Rotary movement is used to drill holes or to insert screws, wires, or pins. Reciprocating
and oscillating movements are used to cut or remove bone. Alternating movement should
not be sued.
What is the most likely cause of a rapid decrease in blood pressure and heart rate for a
patient being infused when 1.5% glycine is used for irrigation?
A. Anaphylactic reaction
B. Myocardial infarction
C. TUR syndrome
D. Pulmonary embolus - Correct Answer C. TUR syndrome
The patient is most likely experiencing TUR syndrome associated excessive glycine
absorption.
Preoperative teaching is most effective when patients have a readiness to learn and the
perioperative nurse teaches from ________ different levels.
A. Two
B. Three
C. Four
