Question 1

Which topical antimicrobial is most appropriate for MRSA-infected wounds?

Accepted Answer

Silver-containing dressings

Answer

Silver-containing dressings have broad-spectrum antimicrobial activity effective against MRSA and are widely used for infected chronic wounds.

Question 2

What is the primary mechanism of action of cadexomer iodine in wound care?

Accepted Answer

Absorbs exudate and releases iodine slowly

Answer

Cadexomer iodine absorbs exudate through its microsphere structure while releasing iodine slowly for sustained antimicrobial activity.

Question 3

Which concentration of povidone-iodine is considered safe for chronic wound use?

Accepted Answer

0.5% or lower

Answer

Concentrations of 0.5% or lower are considered safe for chronic wounds, as higher concentrations are cytotoxic to healing cells.

Question 4

Honey-based wound dressings exert antimicrobial effects primarily through which mechanism?

Accepted Answer

High osmotic pressure and hydrogen peroxide production

Answer

Medical-grade honey creates high osmotic pressure and generates hydrogen peroxide through glucose oxidase activity, providing antimicrobial effects.

Question 5

Which topical agent should be AVOIDED in wounds with exposed cartilage or bone due to cytotoxicity?

Accepted Answer

Full-strength Dakin's solution

Answer

Full-strength Dakin's solution (0.5% sodium hypochlorite) is highly cytotoxic and should be avoided on viable tissue, exposed bone, or cartilage.
