AORN PERIOP 101 COMPREHENSIVE TEST QUESTIONS AND SOLUTIONS
SET TWO
⩥ Gas that is blown into a body cavity for visualization. Answer:
Insufflation
⩥ No-fly zone. Answer: • Restricted area reserved for imaging
equipment
• Other necessary equipment is positioned outside of this area or moved
to allow for imaging equipment use
⩥ Practices to reduce the risk for patient injures and complications
associated with gas insufflation are:. Answer: • Placing the insufflator
above the level of the surgical cavity
• Checking that the alarms are on and audible
• Ensuring that a hydrophobic filter is between the insufflator and the
insufflation tubing
• Flushing the insufflator tubing with the gas that will be used for the
surgery before the tubing is connected to the cannula
• Setting the flow rate according to the manufacturer's instructions for
use and surgeon's preference
o Maintain the pneumoperitoneum at a pressure less than 15 mm/Hg
,• Maintaining insufflation pressure at the lowest level necessary for the
pneumoperitoneum and surgical site visualization
⩥ Clinical signs of a gas embolism include:. Answer: • Dyspnea
• Systemic hypotension
• Cardiac anomalies
• Hypoxemia
• End-tidal CO2 changes
⩥ Intra-abdominal gas embolism is a rare but potentially serious
complication of insufflation because it:. Answer: • Gas increases
abdominal pressures.
• Open blood vessels allow the gas to enter the circulatory system.
• The gas embolism enters the vascular system.
• The embolism travels to the right ventricle or pulmonary artery.
⩥ Gas cylinder safety include:. Answer: • Verify that the correct gas is
being used by checking the cylinder's label, connector, and color coding.
• Make sure there is enough gas in the cylinder.
• Check that the key can open the cylinder.
• Ensure that the cylinder is opened before use.
• Have a second, full cylinder of the same gas being used immediately
available.
,⩥ Fluids can be used to create a surgical working space either by gravity
or pump infusion. The fluid selected is based on the:. Answer: • Surgical
procedure
• Patient assessment
• Instruments used during the surgical procedure
⩥ Low viscosity non-electrolyte fluid is used for:. Answer: •
Gynecological and urological procedures
• Used with monopolar instruments
• Hypotonic
• Can cause transurethral resection syndrome if large quantities are
absorbed
⩥ Examples of Low viscosity non-electrolyte fluids include:. Answer: o
1.5%glycine
o 5% mannitol
o 3% sorbitol
⩥ Normal saline is used:. Answer: • bipolar instruments
• Isotonic
• Contains electrolytes
• Safer than non-electrolyte fluids if large amounts are absorbed
, ⩥ High-viscosity fluid used as:. Answer: • Plasma volume expander
• Can draw six times its own volume into the bloodstream
• Has a high glucose content
⩥ High-viscosity fluid can cause significant complications such as:.
Answer: o Fluid overload
o Heart failure
o Pulmonary edema
⩥ Type(s) of High-viscosity fluid include:. Answer: Dextran
⩥ Benefits of robotic surgery include:. Answer: • Precision o Surgeon
hand, wrist, and finger movements control the movements of the scope
and the thin, lightweight robotic instruments within the patient's body.
• Flexibility
o Robotic instrumentation may have more flexibility and range of
motion than the human wrist.
o Each instrument performs a specific task (eg, coagulation, cutting,
retraction).
• Efficiency o The instrument's quick release from the robotic arm
allows for faster instrument changes during surgery.
• Safety
