Sample interview questions: Can you explain your knowledge of different types of wound healing and factors influencing wound closure?

Sample answer:

Types of Wound Healing

• Primary intention healing: Occurs when wound edges are approximated and closed with minimal tissue loss. Healing progresses by direct apposition of cells across the wound bed.

• Secondary intention healing: Occurs when wound edges are not approximated and the wound bed fills with granulation tissue before epithelialization. Requires more time and resources.

• Tertiary intention healing: Also known as delayed primary closure, involves approximating wound edges after a period of time, allowing for the removal of devitalized tissue and debris.

Factors Influencing Wound Closure

• Intrinsic factors:

  • Tissue type: Vascularization, presence of collagen and growth factors
  • Age: Older adults have slower healing rates
  • Nutritional status: Protein and vitamin deficiencies impair healing
  • Systemic diseases: Diabetes, hypertension, and immunosuppression delay wound closure

• Extrinsic factors:

  • Infection: Delays healing and increases risk of complications
  • Wound size and location: Larger and deeper wounds take longer to heal
