Question 1

In a pediatric trauma patient, which finding MOST reliably indicates significant blood loss?

Accepted Answer

Tachycardia with altered mental status

Answer

Children compensate well and maintain blood pressure until late; tachycardia combined with altered mental status is an earlier and more reliable sign of significant hemorrhage.

Question 2

The BEST indicator of adequate fluid resuscitation in a trauma patient is:

Accepted Answer

Urine output of 0.5 mL/kg/hr in adults

Answer

Urine output of 0.5 mL/kg/hr in adults reflects adequate end-organ perfusion and is the gold standard for fluid resuscitation monitoring.

Question 3

A trauma patient develops Beck's triad. Which intervention is MOST immediately appropriate?

Accepted Answer

Pericardiocentesis

Answer

Beck's triad (hypotension, muffled heart sounds, JVD) indicates cardiac tamponade; pericardiocentesis decompresses the pericardial sac emergently.

Question 4

Which burn depth classification involves destruction of ALL skin layers including subcutaneous tissue, and may appear white, leathery, or charred?

Accepted Answer

Full-thickness (third-degree)

Answer

Full-thickness (third-degree) burns destroy epidermis, dermis, and subcutaneous tissue, presenting as white, leathery, or charred with no pain due to nerve destruction.

Question 5

Accepted Answer

18%

Answer

The anterior trunk (chest and abdomen) represents 18% of TBSA in adults using the Rule of Nines.
