A patient receiving negative pressure wound therapy (NPWT) develops sudden bright red blood in the drainage tubing. The FIRST action the wound care clinician should take is:
Answer: Discontinue NPWT and apply direct pressure
Sudden bright red blood signals active hemorrhage; NPWT must be stopped immediately and direct pressure applied to control bleeding before any other action.
Which statement BEST describes the role of matrix metalloproteinases (MMPs) in chronic wounds?
Answer: MMPs are elevated and cause excessive degradation of the extracellular matrix, impairing healing
Chronic wounds have elevated MMP levels that degrade growth factors, collagen, and fibronectin, creating a proteolytic environment that impedes healing.
For a venous leg ulcer, the MINIMUM ankle-brachial index (ABI) generally required before applying full compression (40 mmHg) is:
Answer: 0.8
An ABI of 0.8 or above is the accepted threshold for safe application of full therapeutic compression therapy for venous ulcers.
A wound with 100% black eschar on the heel of an immobile patient should initially be treated by:
Answer: Leaving it intact and monitoring for signs of infection
Stable, dry, non-infected heel eschar should be left intact per NPUAP/EPUAP guidelines, as it serves as the body's natural cover over an ischemic area.
Which wound bed preparation concept is captured by the acronym TIME?
Answer: Tissue, Infection/Inflammation, Moisture, Edge
TIME stands for Tissue (non-viable), Infection/Inflammation, Moisture imbalance, and Edge (non-advancing or undermined), guiding wound bed preparation.
Hyperbaric oxygen therapy (HBOT) is MOST indicated for which wound type?
Answer: Diabetic foot ulcer with compromised tissue perfusion unresponsive to standard care
HBOT is evidence-supported for Wagner Grade 3+ diabetic foot ulcers with hypoxic tissue that fails to respond to standard wound care.
When assessing wound depth using a cotton-tipped applicator, the clinician identifies that the probe contacts bone. This finding most likely indicates:
Answer: Suspected osteomyelitis requiring further evaluation
A positive probe-to-bone test is highly predictive of osteomyelitis and should prompt further workup including imaging and possible bone biopsy.
