Question 1

A trauma patient arrives with a Glasgow Coma Scale (GCS) score of 8. Which component breakdown best reflects this score?

Accepted Answer

Eye opening 2, Verbal 2, Motor 4

Answer

GCS = Eye (1-4) + Verbal (1-5) + Motor (1-6); 2+2+4=8 is a valid combination reflecting severe neurological compromise.

Question 2

Which finding is the MOST reliable early indicator of hemorrhagic shock in an adult trauma patient?

Accepted Answer

Tachycardia greater than 100 bpm

Answer

Tachycardia is the earliest compensatory response to hemorrhage, occurring before hypotension or oliguria become apparent.

Question 3

A patient sustains a stab wound to the right chest and develops absent breath sounds on the right with tracheal deviation to the left. The priority intervention is:

Accepted Answer

Needle decompression of the right chest

Answer

Tracheal deviation away from the affected side with absent breath sounds indicates tension pneumothorax, requiring immediate needle decompression at the 2nd intercostal space, midclavicular line.

Question 4

Which burn injury requires immediate transport to a burn center according to American Burn Association criteria?

Accepted Answer

Partial-thickness burns covering 12% TBSA in a 25-year-old

Answer

Partial-thickness burns exceeding 10% TBSA in adults meet ABA criteria for burn center referral.

Question 5

In a patient with suspected increased intracranial pressure (ICP), which nursing intervention should be AVOIDED?

Accepted Answer

Routine suctioning every 2 hours regardless of need

Answer

Routine suctioning stimulates coughing and Valsalva maneuver, transiently elevating ICP and worsening cerebral perfusion.
