Deck 32: Endoscopy and Robotic-Assisted Surgery

Question 1

When would a sterile endoscope and accessories be used for performing an endoscopy procedure that is normally aseptic,such as a colonoscopy?

A)If the patient has HIV or has received chemotherapy
B)If the scope has been accidentally sterilized
C)If the scope were contaminated and sterility is compromised
D)If the procedure room has not been properly decontaminated before use

Answer 1

A
Only sterile endoscopes and accessories should be used on patients with suppressed immune systems,such as those who have received chemotherapy or steroid therapy or who have human immunodeficiency virus (HIV)-related diseases.

Question 2

Which endoscopy procedure is usually not performed sterile?

A)Colonoscopy
B)Cystoscopy
C)Hysteroscopy
D)Laparoscopy

Answer 2

A
A colonoscopy is generally performed as an aseptic procedure and is not sterile.The anus normally harbors resident and transient microorganisms.Patients and personnel are protected from cross-contamination by wearing recommended PPE.

Question 3

A Veress needle is used to create access into the peritoneal cavity with the closed method.

Answer 3

True
When using the closed method,a tiny nick is incised into the skin and a Veress spring-loaded needle is placed through the skin into the peritoneal cavity.The delivery of an expansion medium such as gas creates a working space.

Question 4

What type of laparoscope has a single telescopic rod-lens with no accessory port?

A)Operative
B)Diagnostic
C)Bronchoscope
D)Veress

Question 5

One disadvantage of robotic-assisted surgery is the expensive equipment and startup cost needed to perform the procedures.

Question 6

What is the intraoperative peritoneal pressure of an adult during a laparoscopic procedure when using CO₂?

A)5 to 7 mm Hg
B)7 to 10 mm Hg
C)12 to 15 mm Hg
D)Greater than 18 mm Hg

Question 7

What type of gas medium is used to insufflate the peritoneal cavity?

A)Nitrous oxide
B)Oxygen
C)Carbon dioxide
D)Argon

Question 8

When using a robotic system to perform a surgical procedure,the surgeon is required to give the robot commands to activate its actions.

Question 9

Which is a hazard associated with endoscopic procedures?

A)Increased pain
B)Increased incision healing time
C)Increased risk of gas embolism
D)Increased infection rate

Question 10

Incisions of 5 mm made in adults for endoscopic procedures do not need to be sutured closed because they are so small.

Question 11

The surgeon may place more than one trocar during puncture endoscopy.

Question 12

After an endoscopic procedure,it is acceptable to evacuate the CO₂ into the room air because the OR staff are wearing masks.

Question 13

A patient may be at risk for hypothermia if the carbon dioxide gas is not passed through a heating and humidifying element.

Question 14

What can be attached to the endoscope that enables the surgical team to view the anatomy at the same time?

A)Monitor
B)Computer
C)Microscope
D)Camera

Question 15

Lasers are not able to be used with endoscopic or laparoscopic procedures because of the limited vision endoscopy allows.

Question 16

Which trocar has an exposed tip shaped like a pyramid or cone?

A)Blunt
B)Sharp
C)Shielded
D)Initial

Question 17

Fiberoptic lighting is nonglaring and cool inside the patient.This makes it safe to lay the light source on the drapes.

Question 18

Fluid can be used as an expansion media for creating working space while using a scope.

Question 19

For what reason may a hand-assisted access sleeve be used in a laparoscopic procedure?

A)To keep the surgeon's hands warm during the procedure
B)To allow insertion of the surgeon's hand to palpate or grasp an organ
C)To place pressure on a vessel that is bleeding
D)To lose the peritoneum and convert to an open procedure

Question 20

The open method of gaining access into the body is by placing a trocar and sheath so that the expansion medium may be placed through the port.

Question 21

Natural Orifice Transluminal Endoscopic Surgery (NOTES)is a newer form of endoscopic surgery in which only two incisions are made on the patient's abdomen to remove an appendix or a gallbladder.

Question 22

Endoscopes must be cleaned according to manufacturer's recommendations to prevent damaging them and proper removal of debris.
