Silver-containing dressings are MOST indicated for which wound condition?
Answer: Critically colonized or locally infected wound
Silver-containing dressings release silver ions that provide broad-spectrum antimicrobial activity, making them appropriate for critically colonized or locally infected wounds.
A honey-impregnated dressing works through which PRIMARY mechanism?
Answer: Osmotic action and hydrogen peroxide generation
Medical-grade honey exerts antimicrobial effects primarily through osmotic activity and low-level hydrogen peroxide production.
Which statement about contact layer dressings is CORRECT?
Answer: They are placed directly on the wound bed and allow exudate to pass through
Contact layer dressings are low-adherent materials placed on the wound surface to allow exudate passage to a secondary absorbent dressing.
Metronidazole gel applied topically to a fungating wound primarily serves to:
Answer: Reduce malodor caused by anaerobic bacteria
Topical metronidazole gel targets anaerobic bacteria that produce volatile fatty acids responsible for wound malodor in fungating wounds.
A patient's wound shows periwound maceration. The BEST immediate intervention is to:
Answer: Switch to a more absorptive dressing and apply a skin protectant to the periwound
Maceration results from excess moisture; switching to a higher-absorbency dressing and protecting periwound skin with a moisture barrier addresses the cause.
Which of the following is a PRIMARY indication for collagen dressings?
Answer: Stalled or non-healing chronic wounds to stimulate granulation
Collagen dressings provide extracellular matrix scaffolding and growth factors that help stimulate granulation in stalled chronic wounds.
Iodosorb (cadexomer iodine) dressing changes are typically recommended at which frequency?
Answer: Every 72 hours or when saturated
Cadexomer iodine dressings are changed when they become saturated — typically every 2–3 days — or as dictated by exudate levels.
