CST Wound Closure & Healing 2

Question 1

Which layer of the abdominal wall is typically closed with a continuous (running) suture to prevent evisceration?

Accepted Answer

Fascia

Answer

The fascial layer provides the primary structural strength of the abdominal wall closure and is sutured with a continuous technique to distribute tension evenly.

Question 2

A wound that is intentionally left open to heal from the bottom up is classified as healing by:

Accepted Answer

Secondary intention

Answer

Secondary intention healing occurs when wound edges are not approximated and the wound fills in with granulation tissue from the base upward.

Question 3

Which suture material is MOST appropriate for closing skin in a patient with a known latex allergy?

Accepted Answer

Nylon monofilament

Answer

Nylon monofilament (e.g., Ethilon) is a synthetic suture with no latex components and is safe for patients with latex allergies.

Question 4

The surgical technologist notices the surgeon is using a retention suture. What is the PRIMARY purpose of retention sutures?

Accepted Answer

To provide additional support in high-tension closures

Answer

Retention (stay) sutures provide additional mechanical support across a wound under high tension, reducing the risk of dehiscence.

Question 5

Which phase of wound healing is characterized by the formation of new blood vessels (angiogenesis)?

Accepted Answer

Proliferative phase

Answer

Angiogenesis occurs during the proliferative phase as new capillaries grow into the wound bed to support granulation tissue formation.
