Which growth factor is most critical for stimulating fibroblast proliferation during the proliferative phase of wound healing?
Answer: Platelet-derived growth factor (PDGF)
PDGF is released from platelets and macrophages and is a primary chemotactic and mitogenic signal for fibroblasts during the proliferative phase.
A wound with yellow, stringy tissue adhering to the wound bed is described as containing which type of tissue?
Answer: Slough
Slough is devitalized, moist, yellow or tan stringy tissue that must be debrided to facilitate wound healing.
Which dressing type creates a moist wound environment while being appropriate for a heavily exudating wound?
Answer: Alginate
Alginate dressings are highly absorbent and derived from seaweed, making them ideal for heavily exudating wounds.
In which phase of wound healing does angiogenesis primarily occur?
Answer: Proliferative
Angiogenesis, the formation of new blood vessels, occurs primarily during the proliferative phase to support the growing granulation tissue.
A patient has a wound that has been open for 10 weeks with no signs of healing progression. This is classified as:
Answer: Chronic wound
A wound that fails to progress through normal healing stages within 4–6 weeks is classified as a chronic wound.
Which bacteria is most commonly associated with biofilm formation that impedes chronic wound healing?
Answer: Staphylococcus aureus
Staphylococcus aureus, including MRSA strains, is the most prevalent organism found in chronic wound biofilms.
The TIME wound bed preparation framework stands for Tissue, Infection/Inflammation, Moisture imbalance, and:
Answer: Edge of wound/Epithelial advancement
The 'E' in TIME refers to Edge of wound/Epithelial advancement, assessing whether wound edges are progressing and epithelializing.
