Wound Care Certification Exam Wound Care Certification Infection Management and Antimicrobials 3

Question 1

What characteristic of biofilm makes it resistant to antibiotics?

Accepted Answer

Extracellular matrix protects bacteria from antibiotics and immune cells

Answer

The extracellular polymeric substance (EPS) matrix of biofilm acts as a physical barrier protecting bacteria from antibiotics and the host immune response.

Question 2

Which intervention is MOST effective for disrupting wound biofilm?

Accepted Answer

Mechanical debridement combined with antimicrobial therapy

Answer

Mechanical debridement physically disrupts the biofilm structure, and combined with antimicrobial therapy provides the most effective biofilm management.

Question 3

How quickly can biofilm reform on a wound after debridement?

Accepted Answer

24-72 hours

Answer

Biofilm can begin reforming within 24-72 hours after debridement, necessitating consistent wound maintenance and antimicrobial strategies.

Question 4

Which clinical sign is MOST suggestive of biofilm presence in a chronic wound?

Accepted Answer

Wound that fails to progress despite appropriate care

Answer

Failure to progress (wound stagnation) despite appropriate care is the most common clinical indicator of biofilm presence in chronic wounds.

Question 5

Which statement about MRSA wound infections is correct?

Accepted Answer

MRSA requires vancomycin or alternative antibiotics for systemic treatment

Answer

MRSA is resistant to beta-lactam antibiotics and typically requires vancomycin, daptomycin, or linezolid for systemic treatment.
