TNCC Shock Recognition 2

Question 1

A trauma patient has a BP of 88/60 mmHg, HR 128 bpm, and cool, mottled skin after a stab wound to the abdomen. Which shock classification best fits this presentation?

Accepted Answer

Class III hemorrhagic shock

Answer

Class III hemorrhagic shock involves 30–40% blood volume loss and presents with marked tachycardia, hypotension, and altered perfusion signs.

Question 2

Which parameter is the MOST sensitive early indicator of hemorrhagic shock in a healthy adult?

Accepted Answer

Heart rate

Answer

Heart rate rises early as a compensatory mechanism before blood pressure drops, making it the most sensitive early indicator.

Question 3

A patient in neurogenic shock following spinal cord injury would MOST likely present with:

Accepted Answer

Bradycardia and hypotension with warm skin

Answer

Loss of sympathetic tone in neurogenic shock causes bradycardia, hypotension, and vasodilation resulting in warm, dry skin.

Question 4

Obstructive shock from tension pneumothorax is BEST distinguished from other shock types by the presence of:

Accepted Answer

Absent breath sounds and tracheal deviation

Answer

Absent or diminished breath sounds with tracheal deviation away from the affected side are hallmark signs of tension pneumothorax causing obstructive shock.

Question 5

The MOST immediate intervention for a trauma patient in decompensated hemorrhagic shock is:

Accepted Answer

Controlling the source of hemorrhage

Answer

Hemorrhage control is the definitive intervention in hemorrhagic shock because ongoing blood loss cannot be corrected with fluids alone.
