Question 1

Which of the following is a PRIMARY survey finding that requires IMMEDIATE intervention?

Accepted Answer

Open pneumothorax (sucking chest wound)

Answer

An open pneumothorax allows air to enter the pleural space with each breath, rapidly causing respiratory failure and must be immediately sealed with an occlusive dressing.

Question 2

In the primary survey, the 'E' in ABCDE stands for Exposure. What is the KEY nursing consideration during this step?

Accepted Answer

Fully undressing the patient while preventing hypothermia

Answer

Full exposure allows identification of all injuries, but active warming measures must immediately prevent hypothermia, which worsens coagulopathy.

Question 3

A patient with a traumatic amputation of the right hand is brought to the ED. How should the amputated part be transported?

Accepted Answer

Wrapped in moist sterile gauze, placed in a sealed bag on ice

Answer

The amputated part should be wrapped in moist sterile gauze, sealed in a plastic bag, then placed on ice — direct contact with ice causes tissue damage.

Question 4

Which sign is MOST suggestive of a basilar skull fracture?

Accepted Answer

Battle's sign (ecchymosis over mastoid) and raccoon eyes

Answer

Battle's sign (retroauricular ecchymosis) and periorbital ecchymosis (raccoon eyes) are classic late signs of basilar skull fracture.

Question 5

A trauma patient develops neurogenic shock after a cervical spinal cord injury. What hemodynamic pattern differentiates neurogenic shock from hemorrhagic shock?

Accepted Answer

Hypotension with bradycardia and warm skin

Answer

Neurogenic shock presents with hypotension, bradycardia, and warm/flushed skin due to loss of sympathetic tone — unlike hemorrhagic shock which causes tachycardia and vasoconstriction.
