Question 1

A retention (tension) suture is placed to prevent wound dehiscence primarily in which type of patient?

Accepted Answer

Patients with compromised wound healing such as obese, malnourished, or immunosuppressed patients

Answer

Retention sutures provide supplemental full-thickness support in high-risk patients whose primary closure may fail due to poor healing factors.

Question 2

What is the purpose of applying a bolster or bumper over a tie-over dressing in skin graft surgery?

Accepted Answer

To immobilize the graft against the recipient bed, preventing hematoma and shear that disrupts neovascularization

Answer

The bolster dressing maintains uniform pressure on the graft, preventing fluid accumulation and movement that would disrupt the new blood supply.

Question 3

Which clamp is most commonly used to temporarily occlude a vessel for hemostasis during vascular anastomosis?

Accepted Answer

Bulldog clamp

Answer

Bulldog clamps (and similar atraumatic vascular clamps) apply controlled, gentle pressure to occlude vessels without crushing the vessel wall.

Question 4

When tying a surgeon's knot, how does the first throw differ from a standard square knot?

Accepted Answer

The first throw wraps twice around the needle holder (double throw) for added friction to prevent slipping

Answer

A surgeon's knot starts with a double throw (two wraps) on the first pass, creating extra friction that holds the loop in place while the second throw is placed.

Question 5

Which hemostatic clamp is used to control bleeding from medium-to-large vessels and has transverse serrations along its full jaw length?

Accepted Answer

Rochester-Pean clamp

Answer

The Rochester-Pean clamp is a large hemostat with full-length transverse serrations, designed for clamping larger tissue bundles and vessels.
