Correct answer is: Lower cost of equipment

Q.8 Which position is commonly used in laparoscopic pelvic surgery?

Supine
Prone
Trendelenburg
Lateral decubitus
Explanation - The Trendelenburg position improves visualization of pelvic structures by shifting abdominal contents upward.
Correct answer is: Trendelenburg

Q.9 What is the role of trocars in minimally invasive surgery?

Drain fluids
Provide instrument access
Deliver anesthesia
Suture tissues
Explanation - Trocars are ports inserted into the abdomen to allow passage of laparoscopic instruments.
Correct answer is: Provide instrument access

Q.10 What is the main risk associated with CO2 insufflation?

Hypercapnia
Hypoglycemia
Hypokalemia
Hyponatremia
Explanation - Absorption of CO2 during insufflation may lead to elevated CO2 levels in the blood, causing hypercapnia.
Correct answer is: Hypercapnia

Q.11 Which of the following is a common minimally invasive approach for appendectomy?

Endoscopic retrograde cholangiopancreatography
Thoracoscopic appendectomy
Laparoscopic appendectomy
Robotic nephrectomy
Explanation - Laparoscopic appendectomy is the standard minimally invasive method for appendicitis treatment.
Correct answer is: Laparoscopic appendectomy

Q.12 What is the purpose of using insufflators in laparoscopic surgery?

To deliver anesthesia
To create pneumoperitoneum
To sterilize instruments
To suction fluids
Explanation - Insufflators introduce CO2 gas to create pneumoperitoneum, providing working space for laparoscopic surgery.
Correct answer is: To create pneumoperitoneum

Q.13 Which minimally invasive technique is used for joint surgeries?

Endoscopy
Arthroscopy
Thoracoscopy
Colonoscopy
Explanation - Arthroscopy is a minimally invasive surgical procedure used for diagnosing and treating joint problems.
Correct answer is: Arthroscopy

Q.14 Which of the following is a disadvantage of robotic surgery?

3D visualization
Enhanced precision
High cost
Reduced tremor
Explanation - Despite its benefits, robotic surgery is limited by the very high cost of equipment and maintenance.
Correct answer is: High cost

Q.15 What is the average size of a laparoscopic incision?

1–2 cm
5–6 cm
10–12 cm
15 cm
Explanation - Laparoscopic incisions are small, typically around 1–2 cm, compared to larger open surgery incisions.
Correct answer is: 1–2 cm

Q.16 Which energy source is commonly used for tissue dissection in laparoscopic surgery?

Cryotherapy
Electrocautery
