Questions and CORRECT Answers
1. What are the 3 phases of wound Lag phase (haemostasis and inflammation), prolifer-
healing? ation phase, and maturation phase
2. What occurs during the lag phase? Haemostasis and inflammation
3. What occurs first during the lag Vasoconstriction
phase, vasoconstriction or vasodila-
tion?
4. How are compromised blood vessels Blood vessels constrict
resolved during the lag phase? Intrinsic and extrinsic clotting cascades activated
leading to platelet aggregation
Platelet plug stabilised by fibrin
5. What does vasodilation enable dur- Chemotaxis of inflammatory cells to the site of injury
ing the lag phase?
6. How long should the lag phase last 3-5 days
without complications?
7. How long should it take for 5-10 minutes
haemostasis to occur in the lag
phase?
8. What are the 5 signs of inflamma- Pain
tion? Swelling
Redness
Heat
Impaired function
9. What occurs during inflammation Vasodilation and increased vascular permeability al-
during the lag phase? lows chemotaxis of inflammatory cells > natural de-
, bridement
Slough and exudate produced
10. Which stage of wound healing do Inflammation (lag pahse)
clinicians have the most influence
during?
11. How can you influence the lag By providing good haemostasis, irrigation and de-
phase? bridement, and adequate drainage
12. What occurs during the proliferation Angiogenesis
phase? Formation of granulation tissue (fibroplasia)
Epithelialisation and wound contraction
13. What does the formation of granula- Some wound strength and increased resistance to
tion tissue provide? infection
14. What is the proliferation phase char- Pale pink ephithelialisation at the edges of the wound
acterised by? and bright red granulation tissue at the centre
15. Which is the predominant cell type in Fibroblasts
the formation of granulation tissue?
16. What do fibroblasts produce during Collagen, elastin, and extracellular matrix
the proliferation phase?
17. What does epithelialisation lead to? Wound contraction
18. What stage of wound healing is this? Proliferation/repair phase
