- Mixter clamp
- Hartmann clamp (Correct answer)
- Kelly clamp
- Allis clamp
Correct answer: Hartmann clamp

Question 2: A self-retaining retractor that uses a ratchet mechanism to maintain exposure without manual assistance is called a:
- Army-Navy retractor
- Richardson retractor
- Weitlaner retractor (Correct answer)
- Deaver retractor

Question 3: Which suture needle point is most appropriate for suturing delicate vascular tissue?
- Cutting needle
- Reverse cutting needle
- Taper needle (Correct answer)
- Blunt needle
Correct answer: Taper needle
Taper (round) needles are used for vascular tissue because they push tissue aside rather than cutting, reducing the risk of vessel tearing.
Question 4: The electrosurgical unit (ESU) dispersive electrode should be placed:
- Over a bony prominence
- On the patient's back near the spine
- On a large muscle mass close to the operative site (Correct answer)
- Over a scar or skin lesion
Correct answer: On a large muscle mass close to the operative site
The dispersive electrode should be placed on a large, well-vascularized muscle mass near the operative site to ensure safe current return.
Question 5: Which instrument is used to grasp and manipulate the intestine without crushing the tissue?
- Kocher clamp
- Babcock forceps (Correct answer)
- Allis forceps
- Ochsner clamp
Correct answer: Babcock forceps
Babcock forceps have a fenestrated, atraumatic tip designed to grasp delicate structures like the bowel without crushing them.
Question 6: What is the primary purpose of a trocar in laparoscopic surgery?
- To cut tissue during insufflation
- To provide a port of entry for instruments through the abdominal wall (Correct answer)
- To measure intraabdominal pressure
- To aspirate blood from the peritoneal cavity
Correct answer: To provide a port of entry for instruments through the abdominal wall
A trocar creates and maintains a port of entry through the abdominal wall for laparoscopic instruments and the camera.
