CSFA Intraoperative Surgical Procedures 4 — Questions and Answers
Question 1: During a robotic-assisted prostatectomy, the surgical first assistant's primary role at the bedside includes:
- Controlling the robotic arms from the console
- Exchanging instruments, managing specimen extraction, and assisting with stapling (Correct answer)
- Programming the robotic system for each step
- Monitoring anesthesia parameters
Correct answer: Exchanging instruments, managing specimen extraction, and assisting with stapling
The bedside assistant in robotic surgery exchanges instruments, manages suction/irrigation, and performs tasks the robot cannot do autonomously.
Question 2: Which tissue layer must be closed separately during a Pfannenstiel incision closure to prevent hernia formation?
- Skin only
- Rectus abdominis muscle
- Anterior rectus sheath (fascia) (Correct answer)
- Subcutaneous fat
Correct answer: Anterior rectus sheath (fascia)
The anterior rectus sheath is the primary load-bearing layer; failure to close it properly leads to incisional hernia.
Question 3: A patient under general anesthesia has a sudden rise in end-tidal CO2 and body temperature during orthopedic surgery. The surgical first assistant should:
- Continue operating and monitor
- Immediately notify the anesthesia team and surgeon of possible malignant hyperthermia (Correct answer)
- Apply ice packs to the surgical field
- Increase retraction pressure to speed up the case
Correct answer: Immediately notify the anesthesia team and surgeon of possible malignant hyperthermia
Rising ETCO2 with hyperthermia during anesthesia is a classic early sign of malignant hyperthermia, requiring immediate team notification and dantrolene administration.
Question 4: When using a harmonic scalpel (ultrasonic energy device), the surgical first assistant should avoid:
- Using it near vascular pedicles
- Activating it while the blade is in contact with metal clips or other instruments (Correct answer)
- Using it for soft tissue dissection
- Applying it to fatty tissue
Correct answer: Activating it while the blade is in contact with metal clips or other instruments
Activating an ultrasonic device while touching metal can transfer energy to unintended structures, causing burns or device damage.
Question 5: During a hepatic resection, the Pringle maneuver is used to control inflow. This maneuver involves clamping the:
- Inferior vena cava
- Hepatic veins only
- Portal triad (hepatoduodenal ligament containing portal vein, hepatic artery, and bile duct) (Correct answer)
- Splenic artery
Correct answer: Portal triad (hepatoduodenal ligament containing portal vein, hepatic artery, and bile duct)
The Pringle maneuver clamps the hepatoduodenal ligament to occlude portal vein and hepatic artery inflow, reducing hepatic hemorrhage.
Question 6: When passing a suture loaded on a needle holder to the surgeon, the surgical first assistant should present it in which orientation?
- Needle tip pointing toward the surgical first assistant
- Needle in supinated position with the curve oriented for immediate use by the surgeon's dominant hand (Correct answer)
- Needle unloaded from the holder for safety
- Needle loaded backward on the holder
Correct answer: Needle in supinated position with the curve oriented for immediate use by the surgeon's dominant hand
Presenting the needle with the curve properly oriented for the surgeon's dominant hand allows immediate use without repositioning.
Question 7: In vascular surgery, which action by the surgical first assistant best prevents intimal injury when handling a vessel graft?
- Grasping the graft firmly with non-atraumatic clamps
- Handling only the adventitial surface and avoiding forceps on the intimal surface (Correct answer)
- Stretching the graft to its full length before placement
- Immersing the graft in dry gauze
Correct answer: Handling only the adventitial surface and avoiding forceps on the intimal surface
Intimal injury promotes thrombosis; grafts should be handled by the outer adventitia only to preserve the inner lining.
