CLT Wound Healing & Tissue Repair 3

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

Using exclusively UV light to sterilize the wound

Answer

Increasing the dose above standard ranges to overcome poor circulation

Answer

Avoiding any perilesional treatment to prevent spreading infection

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

Maximum irradiance to accelerate healing

Answer

Exclusive UVB application to prevent bacterial colonization

Answer

Treatment limited to once per week to prevent tissue overstimulation

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

The brand name of the light therapy device used

Answer

Patient's subjective comfort level only

Answer

The therapist's license number applied to each treatment note

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

The wound is infected and requires antibiotics

Answer

Entry into the maturation phase requiring cessation of light therapy

Answer

Excessive UV exposure that must be reduced

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

Stimulating maximum collagen production immediately

Answer

Inducing epithelialization as quickly as possible

Answer

Applying high-dose NIR to prevent scar formation

Question 6

A wound treated with light therapy for 4 weeks shows no measurable progress. The MOST appropriate next step is:

Accepted Answer

Reassess the treatment protocol, patient factors, and refer to the appropriate healthcare provider

Answer

Double the treatment dose to accelerate healing

Answer

Discontinue light therapy permanently

Answer

Switch to UV therapy without medical consultation

Question 7

Which finding best indicates that a wound has successfully entered the remodeling phase?

Accepted Answer

Wound contraction, decreased depth, and early scar tissue formation

Answer

Increased wound exudate and erythema

Answer

Formation of a fibrin cap over the wound

Answer

Re-emergence of inflammatory cells in wound cultures
