CBM Burn Classification & Assessment 3

Question 1

Which burn wound characteristic is associated with POOR prognosis for spontaneous healing without grafting?

Accepted Answer

Depth extending beyond 3 weeks to re-epithelialize

Answer

Burns that are unlikely to re-epithelialize within 3 weeks typically require skin grafting to prevent hypertrophic scarring and functional loss.

Question 2

When assessing burn severity, which factor contributes MOST to increasing mortality risk in elderly patients?

Accepted Answer

Diminished physiologic reserve and comorbidities

Answer

Elderly patients have reduced physiologic reserve, pre-existing comorbidities, and impaired immune response, all of which significantly worsen burn outcomes.

Question 3

A firefighter sustains burns to the entire right arm and the anterior surface of the right leg. Using the Rule of Nines, what is the estimated TBSA?

Accepted Answer

13.5%

Answer

The entire arm equals 9% TBSA and the anterior leg equals 4.5% TBSA, totaling 13.5% according to the Rule of Nines.

Question 4

Which type of burn is MOST likely to cause systemic toxicity through transdermal absorption of the causative agent?

Accepted Answer

Hydrofluoric acid chemical burn

Answer

Hydrofluoric acid penetrates the skin and releases fluoride ions that bind calcium systemically, causing life-threatening hypocalcemia and cardiac dysrhythmias.

Question 5

In electrical burn assessment, why is surface wound size a poor predictor of injury severity?

Accepted Answer

Current travels internally causing deep tissue necrosis not visible externally

Answer

Electrical current travels through the body along the path of least resistance, causing extensive internal muscle and nerve injury disproportionate to the small entry and exit wounds.
