CBM Special Populations in Burn Care 3

Question 1

To prevent myoglobin-induced acute renal failure after high-voltage electrical burns, urine output should be maintained at:

Accepted Answer

1-2 mL/kg/hour until urine clears

Answer

0.5 mL/kg/hour

Answer

0.5-1.0 mL/kg/hour

Answer

Greater than 3 mL/kg/hour continuously

Question 2

High-voltage electrical injury (>1000 volts) requires continuous cardiac monitoring because:

Accepted Answer

Current traversing the thorax can trigger cardiac arrhythmias including ventricular fibrillation

Answer

Pericarditis is the most common late complication

Answer

Aortic dissection occurs from electrical pressure waves

Answer

Mitral valve regurgitation develops from electrothermal heating

Question 3

The presence of both entry and exit wounds in an electrical burn patient indicates that:

Accepted Answer

Current traveled through internal organs and tissues along its conduction path

Answer

The patient simultaneously contacted two separate electrical sources

Answer

Current dispersed uniformly across all skin surfaces

Answer

The injury resulted from arc flash rather than direct contact

Question 4

Pregnant burn patients with burns greater than 40% TBSA face sharply increased fetal mortality primarily due to:

Accepted Answer

Maternal hypoperfusion causing uteroplacental insufficiency

Answer

Teratogenic effects of topical antimicrobial agents used in burn care

Answer

Direct thermal penetration through the abdominal wall to the uterus

Answer

Amniotic fluid evaporation from heat exposure

Question 5

Patients with diabetic peripheral neuropathy may present with delayed burn diagnosis because:

Accepted Answer

Impaired pain sensation prevents recognition of the initial thermal injury

Answer

Their burns heal faster, making them less visible at presentation

Answer

Inflammation is accelerated, masking the typical appearance of the wound

Answer

Blood glucose fluctuations mimic early burn sepsis symptoms

Question 6

Radiation burns differ from thermal burns in that they typically:

Accepted Answer

Exhibit a latent period before tissue damage becomes clinically apparent

Answer

Heal within 48 hours due to active cellular repair mechanisms

Answer

Require more aggressive early surgical debridement than thermal burns

Answer

Respond well to standard topical antimicrobial protocols as the sole treatment

Question 7

When calculating fluid resuscitation for morbidly obese burn patients, standard weight-based formulas should be adjusted because using actual body weight may:

Accepted Answer

Lead to dangerous fluid overload and abdominal compartment syndrome

Answer

Underestimate fluid needs since obese patients have higher insensible losses

Answer

Underestimate needs because adipose tissue has a larger vascular bed

Answer

Accelerate their altered metabolism causing rapid fluid depletion
