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

Urine output of 1-2 mL/kg/hour is targeted in electrical injury with myoglobinuria to ensure adequate renal tubule flow to clear myoglobin until the urine returns to clear yellow.

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

High-voltage electrical current passing through the thorax can cause cardiac arrhythmias including ventricular fibrillation, requiring continuous ECG monitoring after electrical injury.

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

Entry and exit wounds indicate current passed through internal structures along a conduction path, potentially causing deep tissue injury and organ damage not visible on surface examination.

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

Burn shock causes maternal hypoperfusion which compromises uteroplacental circulation and fetal oxygenation, dramatically increasing fetal mortality in major burn cases.

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

Diabetic neuropathy impairs pain perception so patients may not feel a burn injury occurring, leading to delayed presentation with more extensive and often deeper tissue damage.
