Wound Closure & Healing Flashcards

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

Answer: Fascia

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

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

Answer: Secondary intention

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

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

Answer: Nylon monofilament

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

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

Answer: To provide additional support in high-tension closures

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

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

Answer: Proliferative phase

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

A 3-0 absorbable suture is being used to close subcutaneous tissue. Which of the following is an example of a synthetic absorbable suture?

Answer: Polyglycolic acid (Dexon)

Polyglycolic acid (Dexon) is a synthetic absorbable suture that is broken down by hydrolysis over time.

During wound closure, the scrub technologist should count instruments, sharps, and sponges:

Answer: Before closure of any cavity and at skin closure

Counts must be performed before closure of any body cavity and again at skin closure to ensure no items are retained.
