Question 1

Which feature best distinguishes a hypertrophic scar from a keloid?

Accepted Answer

A hypertrophic scar stays within the borders of the original wound

Answer

Hypertrophic scars stay within the original wound margins and often regress, while keloids grow beyond them.

Question 2

A patient with a mature hypertrophic burn scar is referred for fractional ablative CO2 laser therapy. What is the main expected benefit?

Accepted Answer

Better scar pliability, texture, and range of motion

Answer

Fractional CO2 laser remodels scar collagen, improving pliability, thickness, texture, and often mobility.

Question 3

A burn patient develops pain and progressive loss of range of motion in one joint weeks after injury, and heterotopic ossification is suspected. Which joint is most commonly affected?

Accepted Answer

Elbow

Answer

The elbow is the most common site of heterotopic ossification in burn patients.

Question 4

A patient with healed burns has intense pruritus that disturbs sleep. Which approach is most appropriate?

Accepted Answer

Frequent fragrance-free moisturizers plus antihistamines or gabapentin as ordered

Answer

Burn pruritus is managed with emollients plus antihistamines or neuromodulators such as gabapentin or pregabalin.

Question 5

Which discharge teaching about sun exposure is correct for a patient with newly healed grafts?

Accepted Answer

Use broad-spectrum SPF 30 or higher and protective clothing for at least the first year

Answer

Immature healed skin is prone to hyperpigmentation and sunburn, so strict sun protection is needed until the scar matures.
