Question

a patient who has received a direct lightning strike will most likely have which of the following?

brain injuries.
burn injuries.
internal bleeding.
spinal cord injuries.

Explanation:

Analyze lightning strike pathophysiology

Using the Environmental Emergencies knowledge point, we analyze how a direct lightning strike affects the human body. Lightning is a massive, instantaneous direct current (DC) discharge. Because of the "flashover" effect, where the current flows primarily over the outside of the body, deep internal tissue destruction and severe deep burns are surprisingly less common than expected. Instead, the nervous system and cardiovascular system are highly sensitive to this massive electrical disruption.

Evaluate the clinical manifestations

The nervous system is highly conductive and particularly vulnerable to electrical injury. A direct strike commonly causes immediate neurological dysfunction, including altered mental status, confusion, amnesia, and temporary paralysis (keraunoparalysis). Therefore, brain injuries (including cognitive deficits and intracranial hemorrhage) are highly characteristic and common.

Compare the options

• Brain injuries: Highly common due to the vulnerability of the central nervous system to massive electrical currents.
• Burn injuries: Often superficial (such as linear or feathering Lichtenberg figures) rather than deep, severe burns due to the flashover effect.
• Internal bleeding: Not a primary or most likely direct result of the electrical current itself.
• Spinal cord injuries: While possible due to secondary trauma (being thrown), direct brain injury is a more common and immediate electrical complication.

Answer:

• (A) Brain injuries. (Correct answer)
• (B) Burn injuries.
• (C) Internal bleeding.
• (D) Spinal cord injuries.
