    Correct

    • What is the maximum strength of a scar versus unwounded skin:

      Your Answer: 0.8

      Explanation:

      Basic healing is complete by 5-10 days but maximal wound strength (80% of normal) may take 12 weeks.

    Correct

    • By the third day of wound healing, which sort of inflammatory cell has predominated:

      Your Answer: Macrophages

      Explanation:

      The inflammatory phase of healing is sometimes called the lag phase because wound strength does not begin to return immediately. The inflammatory phase is completed within three days except in the presence of infection or other factors associated with impaired wound healing. Mononuclear leukocytes accumulate and are transformed into macrophages. The maturation of blood-derived monocytes into macrophages is heralded by several events, including secretion of vimentin, which is a structural filament protein involved in wound healing.

  • Question 3 - Which type of collagen is initially laid down in early wound healing: ...

    Correct

    • Which type of collagen is initially laid down in early wound healing:

      Your Answer: III

      Explanation:

      Fibroblasts migrate to the wound (about 2 – 5 days after wounding), proliferate and secrete extracellular matrix comprising mainly collagen (type III) and fibronectin to plug the gap.

    Correct

    • Which of the following is the correct sequential order of the phases of healing:

      Your Answer: Haemostasis, inflammation, proliferation, remodelling

      Explanation:

      Acute wound healing has four main stages: haemostasis, inflammation, proliferation and remodelling.

    Correct

    • One of the benefits of wound healing through first intention is:

      Your Answer: Minimisation of scar tissue formation

      Explanation:

      Primary wound healing, or healing by first intention, occurs within hours of repairing a full-thickness surgical incision. This surgical insult results in the mortality of a minimal number of cellular constituents. Healing by first intention can occur when the wound edges are opposed, the wound is clean and uninfected and there is minimal loss of cells and tissue i.e. surgical incision wound. The wound margins are joined by fibrin deposition, which is subsequently replaced by collagen and covered by epidermal growth.

    Incorrect

    • What is the primary function of collagen in wound healing?

      Your Answer: Expansion and contraction

      Correct Answer: Strength and support

      Explanation:

      Key elements of the maturation stage include collagen cross-linking, collagen remodelling, wound contraction, and repigmentation. The tensile strength of the wound is directly proportional to the amount of collagen present. Numerous types of collagen have been identified; types I and III predominate in the skin and aponeurotic layers. Initially, a triple helix (tropocollagen) is formed by three protein chains; two are identical alpha-1 protein chains, and the third is an alpha-2 protein.
