Question 1

For a patient with a diabetic foot ulcer, what is the most important modification to a standard light therapy protocol?

Accepted Answer

Monitoring closely due to impaired sensation and risk of undetected adverse effects

Answer

Diabetic patients often have peripheral neuropathy and impaired sensation, requiring close monitoring during treatment since they may not reliably report pain or heat from adverse reactions.

Question 2

When treating a Stage II pressure ulcer with photobiomodulation, which parameter selection is most appropriate?

Accepted Answer

Red/NIR light at evidence-based fluence (2–6 J/cm²) to wound bed and perilesional tissue

Answer

Evidence-based protocols recommend red/NIR photobiomodulation at 2–6 J/cm² fluence applied to both the wound bed and surrounding tissue, balancing efficacy with safety.

Question 3

Which documentation element is most critical when tracking light therapy outcomes for wound healing over time?

Accepted Answer

Sequential wound measurements, photographs, and tissue quality descriptions

Answer

Objective wound assessment requires sequential measurements (length, width, depth), photographic documentation, and tissue quality descriptions to accurately track healing progress over time.

Question 4

What does the presence of healthy granulation tissue in the wound bed indicate?

Accepted Answer

Active proliferative phase healing with positive response to treatment

Answer

Granulation tissue (red, moist, granular-appearing tissue) is a positive indicator of the proliferative phase, showing active fibroblast activity, collagen deposition, and angiogenesis.

Question 5

When treating a post-surgical wound with light therapy in the first 72 hours, what is the primary treatment goal?

Accepted Answer

Modulating inflammation and reducing pain and edema

Answer

In the first 72 hours post-surgery, the priority is modulating the inflammatory response to reduce excessive swelling, pain, and edema while supporting the normal healing process.
