CBRN CBRN Rehabilitation & Scar Management 1 — Questions and Answers
Question 1: What type of scar is characterized by raised, firm, erythematous tissue that remains within the original wound boundaries?
- Keloid scar
- Atrophic scar
- Contracture
- Hypertrophic scar (Correct answer)
Correct answer: Hypertrophic scar
Hypertrophic scars are raised, firm, and erythematous but stay confined within the original wound margins, unlike keloids which extend beyond them.
Question 2: What is the primary purpose of custom-fitted compression garments in burn scar rehabilitation?
- To prevent wound infection
- To reduce acute pain
- To minimize hypertrophic scar formation (Correct answer)
- To prevent fluid shifts
Correct answer: To minimize hypertrophic scar formation
Compression garments apply 20–25 mmHg of continuous pressure to maturing scars, reducing hypertrophic scar formation by limiting collagen deposition.
Question 3: When should compression garment therapy typically begin in burn patients?
- Immediately post-injury
- Six months post-injury
- Only when hypertrophic scarring is already visible
- After complete wound closure (Correct answer)
Correct answer: After complete wound closure
Compression garment therapy begins after complete wound closure to apply pressure during the active scar maturation phase.
Question 4: What is a burn contracture, and which anatomical areas are most commonly affected?
- Infected wound tissue; the feet
- Excessive granulation; the back
- Fluid accumulation; the chest
- Scar tissue limiting joint movement; neck and axilla are common sites (Correct answer)
Correct answer: Scar tissue limiting joint movement; neck and axilla are common sites
A burn contracture is scar tissue that restricts joint movement; the neck and axilla are frequently affected because scars cross flexion points and pull.
Question 5: What is the primary physical therapy intervention for preventing burn contractures during rehabilitation?
- Bed rest and immobilization
- Heat application only
- Massage only
- Range-of-motion exercises and splinting (Correct answer)
Correct answer: Range-of-motion exercises and splinting
Active and passive range-of-motion exercises combined with splinting maintain joint mobility and prevent contracture formation in burn rehabilitation.
Question 6: How long does the burn scar maturation process typically take?
- 2–4 weeks
- 1–2 months
- 5–7 years
- 1–2 years (Correct answer)
Correct answer: 1–2 years
Burn scar maturation is prolonged, typically taking 1–2 years, during which compression, physical therapy, and scar management are needed.
