TNCC Burn Management 2

Question 1

A burn patient arrives with singed nasal hairs, hoarseness, and carbonaceous sputum. What is the priority intervention?

Accepted Answer

Prepare for immediate endotracheal intubation

Answer

Signs of inhalation injury with impending airway compromise require immediate intubation before progressive edema makes the airway inaccessible.

Question 2

Using the Parkland formula, how much lactated Ringer's should be given in the first 8 hours to a 70 kg patient with 40% TBSA burns?

Accepted Answer

5,600 mL

Answer

Parkland formula: 4 mL × kg × %TBSA = 4 × 70 × 40 = 11,200 mL total, with half (5,600 mL) given in the first 8 hours.

Question 3

Which burn depth classification is characterized by blisters, moist wound surface, extreme pain, and blanching with pressure?

Accepted Answer

Superficial partial-thickness (second-degree)

Answer

Superficial partial-thickness burns involve the epidermis and superficial dermis, causing blisters, moisture, intense pain, and preserved capillary refill.

Question 4

A patient with circumferential full-thickness burns to the right arm has absent radial pulse and paresthesias. The priority intervention is:

Accepted Answer

Emergent escharotomy

Answer

Circumferential eschar causes compartment syndrome; escharotomy releases constricting eschar to restore perfusion before nerve and muscle damage occur.

Question 5

Carbon monoxide poisoning should be suspected in a burn patient found in an enclosed space. Which finding is most consistent with CO poisoning?

Accepted Answer

Normal SpO2 with altered mental status

Answer

Pulse oximetry cannot distinguish carboxyhemoglobin from oxyhemoglobin, so SpO2 may appear normal despite significant CO poisoning causing AMS.
