Question 1

During a laparoscopic case, the surgeon reports poor visualization due to fogging of the scope lens. What is the first corrective action?

Accepted Answer

Warm or apply anti-fog solution to the lens before reinsertion

Answer

Warming the scope (in warm saline or with anti-fog solution) before insertion equalizes the temperature differential that causes condensation on the lens.

Question 2

Which type of retractor system uses a fixed frame attached to the operating table to maintain exposure without requiring human assistance?

Accepted Answer

Bookwalter retractor system

Answer

The Bookwalter system attaches to the OR table via a post and ring, allowing multiple interchangeable blades to maintain abdominal exposure without a dedicated assistant.

Question 3

What is the primary safety concern specific to using an argon beam coagulator (ABC)?

Accepted Answer

Argon gas insufflation into the body cavity can cause gas embolism or pneumothorax if the cavity is closed

Answer

Argon gas delivered by the ABC can accumulate in body cavities, creating a risk of gas embolism or tension pneumothorax if there is no exit route for the gas.

Question 4

A powered stapling device fires but the staple line is incomplete. What is the most likely cause?

Accepted Answer

Tissue thickness exceeded the staple cartridge's range, or the cartridge was not fully seated

Answer

Misfire or incomplete staple formation occurs when tissue is thicker than the cartridge accommodates or when the cartridge is not properly locked into the device.

Question 5

When using intraoperative ultrasound, the surgical first assistant should cover the sterile ultrasound probe with:

Accepted Answer

A sterile ultrasound probe cover/sheath specifically designed for intraoperative use

Answer

A sterile probe sheath maintains sterility of the operative field and protects the probe when it contacts intraoperative tissues or fluids.
