100% Accurate Answers
1. During a laparoscopic surgery, if a patient's blood pressure drops significantly
while under CO2 pneumoperitoneum, what should be the immediate course
of action?
Immediately increase the CO2 flow rate.
Administer intravenous fluids without further assessment.
Assess the patient's cardiac rhythm and end tidal CO2 levels.
Continue the procedure without any changes.
2. The OR RN should be aware that risks for patient injury from argon-enhanced
electrocautery is _.
Cardiac arrest
VTE
Air embolism
Gas embolism
3. In which anatomical area is a zero degree laparoscope particularly
advantageous?
Neck
Abdomen
Thorax
Pelvis
,4. What is a key advantage of using nitric oxide in laparoscopic surgery
compared to traditional gases?
Lower risk of infection.
Increased visibility during surgery.
Less acid-base disturbance.
Reduced recovery time.
5. If a patient undergoing laparoscopic surgery experiences oliguria, which
physiological mechanism related to CO2 pneumoperitoneum might explain
this condition?
Decreased intrabdominal pressure causing increased urine
production
Increased CO2 levels stimulating renal function
Increased intrabdominal pressure leading to decreased renal blood
flow
Decreased pressure resulting in increased renal perfusion
6. Kidneys during pneumoperitoneum changes:
decrease renal function
decrease renal blood flow
decrease GFR/UO
all of the above
7. Describe how measuring tissue impedance is important in the process of
bipolar energy delivery.
, Measuring tissue impedance is used to determine the duration of the
surgery.
Measuring tissue impedance is irrelevant to the sealing process.
Measuring tissue impedance ensures that the energy delivered is
appropriate for effective sealing without damaging surrounding
tissues.
Measuring tissue impedance helps in identifying the type of tissue
being operated on.
8. What is the initial incision size required in the Hasson technique for
laparoscopic surgery?
3 cm skin incision
1 cm skin incision
2 cm skin incision
5 cm skin incision
9. What is the most effective way of correcting the adverse pulmonary side
effects from carbon dioxide pneumoperitoneum during laparoscopic
surgery?
Positioning the patient in reverse Trendelenburg position
Adding positive end-expiratory pressure
Decreasing the pressure of the pneumoperitoneum
Increasing minute ventilation
10. What is the relationship between current density and tissue resistance in
monopolar electrosurgery?
Constant
, Unrelated
Directly proportional
Inversely related
11. What is the primary advantage of bipolar electrosurgery over monopolar
electrosurgery in laparoscopic procedures?
Lower cost of instruments
More precise control and reduced risk of thermal injury
Increased tissue cutting speed
Faster procedure times
12. What is the primary use of peritoneal washings/scrapings in laparoscopic
surgery?
To remove excess CO2 from the abdomen.
To assess the effectiveness of electrosurgery.
To obtain prognostic information that may guide further therapy.
To facilitate the insertion of laparoscopic instruments.
13. Which of the following statements is true about capacitative coupling?
Capacitative coupling occurs when the first layer of black insulation
on an instrument fails and the energy is reflected off the yellow
insulation, causing a tissue burn.
Capacitative coupling occurs when an active electrode touches a
noninsulated instrument, allowing the energy to flow from one
instrument to another instrument.
Capacitative coupling occurs when energy is transferred through
intact insulation on an instrument to nearby conductive tissue.
