TNCC Burn and Thermal Trauma 2

Question 1

Electrical burns are often more severe than they appear externally because:

Accepted Answer

Current travels through the body causing extensive internal tissue destruction along its path

Answer

Electrical burns cause extensive internal tissue destruction along the current path through the body, while external entry and exit wounds may appear deceptively small.

Question 2

Which finding is most directly indicative of inhalation injury in a burn patient?

Accepted Answer

Carbonaceous (soot-tinged) sputum

Answer

Carbonaceous sputum containing sooty particles is direct evidence that combustion byproducts were inhaled into the airway, confirming inhalation injury.

Question 3

When monitoring fluid resuscitation in a burn patient, which parameter best indicates adequate tissue perfusion?

Accepted Answer

Urine output of 0.5–1 mL/kg/hour

Answer

Urine output of 0.5–1 mL/kg/hour reflects adequate renal perfusion and is the primary endpoint for titrating fluid resuscitation in burn patients.

Question 4

What is the preferred route for opioid analgesic administration during the acute phase of major burn injury?

Accepted Answer

Intravenous administration

Answer

IV administration is essential in burn patients because impaired peripheral circulation makes subcutaneous and intramuscular routes unreliable for medication absorption.

Question 5

According to American Burn Association guidelines, which patient should be referred to a burn center?

Accepted Answer

Patient with partial-thickness burns greater than 10% TBSA

Answer

The American Burn Association criteria for burn center referral include partial-thickness burns exceeding 10% TBSA due to the complexity of care required.
