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 - 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 - 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 - ANSWER- C. TUR syndrome
The patient is most likely experiencing TUR syndrome associated

There are three different levels of preoperative teaching:
information, psychosocial support, and skill training. Information
should include explanations of procedure and what to expect
throughout the phases of perioperative care. Psychosocial support
includes encouraging the patient to share anxiety and supporting
coping mechanisms. Skill training allows the patient to learn the
skills required to function after the procedure and provides
confidence and understanding.
When caring for a patient with sickle cell anemia, the perioperative
nurse should:
A. Raise the temperature in the operating room to between 26.7*C and
29.4*C (80*F and 85*F).
B. Have relaxing music playing in the operating room to avoid
overstimulation
C. Administer a liter of normal saline prior to surgery to ensure that the
patient is well hydrated
D. Allow a family member or friend to sit with the patient in the
preoperative area and in the post anesthesia care unit. - ANSWER- A.
Raise the temperature in the operating room to between 26.7*C and
29.4*C (80*F and 85*F).

The sickle cell patient must be kept warm to prevent hypothermia
and meet increased demands for oxygen.
A _______ type of fire extinguisher should be used in an operating or
procedure room.
A. Wet chemical
B. Carbon dioxide
C. Halogen
D. Dry powder - ANSWER- B. Carbon dioxide
The National Fire Protection Association recommends using either a
water mist or carbon dioxide extinguisher for extinguishing fires in
the operating room.
_______ requires purposeful, outcomes-directed thought and is driven
by patient need.
A. Critical thinking
B. Assessment
C. Diagnosis
D. Planning - ANSWER- A. Critical thinking
Scientific nursing interventions, critical thinking and clinical
