Question 1

When calculating fluid resuscitation using the Parkland formula (4 mL × kg × %TBSA), what proportion of the total 24-hour volume should be given in the first 8 hours?

Accepted Answer

50%

Answer

The Parkland formula calls for 50% of the calculated 24-hour volume to be infused in the first 8 hours from the time of burn, with the remaining 50% over the next 16 hours.

Question 2

Which circumferential burn complication requires escharotomy and presents with absent distal pulses and a tight, pale extremity?

Accepted Answer

Compartment syndrome from eschar constriction

Answer

Circumferential full-thickness burns create rigid eschar that constricts swelling tissue, causing compartment syndrome that requires escharotomy to restore circulation.

Question 3

A patient has burns to both anterior forearms and the anterior chest. Using the Rule of Nines, what is the approximate TBSA burned?

Accepted Answer

22.5%

Answer

Anterior chest = 18%, each anterior forearm = 4.5% (half of 9% per arm); total = 18 + 4.5 + 4.5 = approximately 22.5% TBSA.

Question 4

What is the primary danger of applying ice directly to a burn wound?

Accepted Answer

It causes frostbite and worsens tissue injury while accelerating hypothermia

Answer

Ice causes vasoconstriction that worsens burn depth, can cause frostbite of injured tissue, and significantly contributes to systemic hypothermia.

Question 5

Which burn characteristic classifies a burn as a 'critical burn' requiring transfer to a burn center per ABA guidelines?

Accepted Answer

Partial thickness burns greater than 10% TBSA in a healthy adult

Answer

The American Burn Association criteria for burn center referral include partial thickness burns >10% TBSA, burns involving face/hands/feet/genitalia/perineum, full thickness burns, and chemical or electrical burns.
