Which topical antimicrobial is most appropriate for MRSA-infected wounds?
Answer: Silver-containing dressings
Silver-containing dressings have broad-spectrum antimicrobial activity effective against MRSA and are widely used for infected chronic wounds.
What is the primary mechanism of action of cadexomer iodine in wound care?
Answer: Absorbs exudate and releases iodine slowly
Cadexomer iodine absorbs exudate through its microsphere structure while releasing iodine slowly for sustained antimicrobial activity.
Which concentration of povidone-iodine is considered safe for chronic wound use?
Answer: 0.5% or lower
Concentrations of 0.5% or lower are considered safe for chronic wounds, as higher concentrations are cytotoxic to healing cells.
Honey-based wound dressings exert antimicrobial effects primarily through which mechanism?
Answer: High osmotic pressure and hydrogen peroxide production
Medical-grade honey creates high osmotic pressure and generates hydrogen peroxide through glucose oxidase activity, providing antimicrobial effects.
Which topical agent should be AVOIDED in wounds with exposed cartilage or bone due to cytotoxicity?
Answer: Full-strength Dakin's solution
Full-strength Dakin's solution (0.5% sodium hypochlorite) is highly cytotoxic and should be avoided on viable tissue, exposed bone, or cartilage.
How long should topical antimicrobial therapy typically continue before reassessing effectiveness?
Answer: 2 weeks
Topical antimicrobial therapy should be reassessed after 2 weeks to determine if wound bioburden is improving and whether therapy should continue or change.
