Question 1

Biofilm in a chronic wound is best described as:

Accepted Answer

An organized bacterial community protected by a polymeric matrix

Answer

Biofilm is a structured, sessile community of bacteria encased in a self-produced extracellular polymeric matrix that confers resistance to antimicrobials and host defenses.

Question 2

Which debridement method relies on the body's own endogenous enzymes and white blood cells to liquefy necrotic tissue?

Accepted Answer

Autolytic debridement

Answer

Autolytic debridement harnesses the body's own phagocytes and proteolytic enzymes, typically facilitated by occlusive or semi-occlusive moisture-retentive dressings.

Question 3

Healthy granulation tissue ready for wound bed closure appears as:

Accepted Answer

Bright beefy red, moist, and granular

Answer

Healthy granulation tissue is bright red, moist, and has a granular cobblestone appearance due to new capillary loops; it bleeds easily when touched.

Question 4

The 'I' component of the TIME framework in wound bed preparation addresses:

Accepted Answer

Infection and inflammation control

Answer

The 'I' in TIME stands for Infection and Inflammation control, including assessment of bacterial burden and management of prolonged or excessive inflammation that impairs healing.

Question 5

Critical colonization in a wound differs from overt infection primarily because:

Accepted Answer

The bacterial load impairs healing without classic systemic infection signs

Answer

Critical colonization represents a bacterial burden high enough to stall wound healing and cause subtle local changes (e.g., increased pain, friable tissue) without frank systemic infection signs.
