Which organism is MOST commonly associated with biofilm formation in chronic wounds?
Answer: Staphylococcus aureus
Staphylococcus aureus is the most frequently identified organism in chronic wound biofilms, contributing to persistent inflammation and healing failure.
What is the PRIMARY mechanism of action of hyperbaric oxygen therapy (HBOT) in wound healing?
Answer: Increases tissue oxygen tension to stimulate angiogenesis and immune function
HBOT delivers 100% oxygen at increased atmospheric pressure, dramatically raising tissue pO2, which stimulates angiogenesis, enhances leukocyte bactericidal activity, and promotes collagen synthesis.
A patient with a sacral pressure injury has black, hard, dry eschar with no fluctuance or drainage. Per NPUAP guidelines, what is the MOST appropriate initial management?
Answer: Leave intact and monitor unless signs of infection develop
Stable, dry eschar on heels and in some sacral locations can serve as a protective biological cover and should not be debrided unless infection signs appear.
Which nutritional marker BEST reflects a patient's acute protein status over the previous 2–3 days?
Answer: Prealbumin (transthyretin)
Prealbumin has a half-life of 2–3 days, making it the most sensitive short-term indicator of acute protein nutritional status compared to albumin's 20-day half-life.
In the context of venous insufficiency wounds, the term 'lipodermatosclerosis' refers to:
Answer: Chronic skin and subcutaneous tissue fibrosis from venous hypertension
Lipodermatosclerosis is fibrosis and induration of the skin and subcutaneous tissue caused by chronic venous hypertension, often presenting with an inverted champagne bottle appearance.
Which cell type is PRIMARILY responsible for wound contraction during the proliferative phase?
Answer: Myofibroblasts
Myofibroblasts, which have contractile properties, are the primary cells driving wound contraction by pulling wound edges together during the proliferative phase.
A patient has a fistula connecting the bowel to the skin surface. Which type of wound management system is MOST appropriate?
Answer: Pouching system with skin barrier wafer
Enterocutaneous fistulas produce enzymatic, high-volume output requiring a pouching system with a skin barrier wafer to protect periwound skin and accurately measure output.
