CST Wound Closure & Healing 3

Question 1

Which suture technique produces the most cosmetically acceptable scar with minimal cross-hatch marks?

Accepted Answer

Subcuticular (intradermal) suture

Answer

The subcuticular suture runs beneath the skin surface, avoiding percutaneous punctures and eliminating cross-hatch scarring.

Question 2

A patient develops a keloid after surgery. This is BEST described as:

Accepted Answer

Excessive collagen deposition extending beyond wound margins

Answer

Keloids result from overproduction of collagen that grows beyond the original wound boundaries, unlike hypertrophic scars which stay within the wound margins.

Question 3

When passing a needle holder loaded with suture to the surgeon, the scrub technologist should:

Accepted Answer

Pass it handle-first with the needle pointing away

Answer

Suture is passed handle-first with the needle pointing away from both the surgeon's and technologist's hands to prevent needlestick injury.

Question 4

Which type of wound closure material works by using tissue adhesive (cyanoacrylate) to bond wound edges?

Accepted Answer

Dermabond

Answer

Dermabond is a topical skin adhesive made of cyanoacrylate that polymerizes on contact with tissue to close superficial wounds.

Question 5

The MOST important factor that delays wound healing in a diabetic patient is:

Accepted Answer

Impaired microvascular circulation and neuropathy

Answer

Diabetes impairs microvascular function and neuropathy reduces sensation, both of which compromise oxygen and nutrient delivery to healing tissue.
