TRAUMA QUESTION SET AND SOLUTIONS
◉ sx can be slow and gradual and silent. hypotension, tachycardia,
arrhythmias and dysrhythmias, visible trauma, distended neck veins,
muffled heart sounds, and other signs of shock.
Note: rapid deceleration
Answer: blunt cardiac injury s and sx
◉ 1.Metabolic acidosis is corrected by control of hemorrhage and
admin of fluids and blood
2.The degree of metabolic acidosis is measured by the base deficit
from the abg's. The base deficit helps estimate level of perfusion and
pt's response to resuscitation
Answer: Acid base balance, base deficit and shock
◉ 1. Normal -2 to 2
2. Mild -5 to -3
3. Moderate -9 to -6*** (-6 or more indicates severe injury and
significant mortality)
4. Severe -10 or more
Answer: Base deficit chart 1. normal 2. mild 3. moderate 4. severe
, ◉ Lactate levels help determine organ perfusion. Obtain lactate
levels and correct to less than 2
Answer: Lactate levels and shock
◉ an abnormality of the circulatory system that results in
inadequate organ perfusion and tissue oxygenation. Reduced tissue
perfusion causes cellular hypoxia-> cellular conversion from aerobic
to anaerobic metabolism ->leads to accumulation of lactic acid ->
metabolic acidosis
Answer: define shock
◉ Urine output measures organ perfusion and adequate
resuscitation
Adults- 0.5 ml/kg/hr
Peds- 1 ml/kg/hr
baby- 2 ml/kg/hr
Answer: Urine output and hypovolemic shock
◉
Answer: epidural hematoma
◉ the airway with cervical spine control
Answer: When multiple victims are present at the scene of a major
motor vehicle crash, the highest priority is given to
