Study Questions and Answers
Q1 Primary assessment, mnemonic
A XABCDE
Q2 Occlusive dressing, defined
A air and water tight dressing with a waxy coating to provide a total seal, resulting in not having the absorbent
properties of gauze pads
Q3 Occlusive dressing, 3 side application
A open pneumothorax (sucking chest wound)
Q4 Occlusive dressing, 4 side application
A gunshot
Q5 First phase
A Involves the circumstances leading up to an injury. Efforts in this phase are primarily focused on injury prevention.
Q6 Event Phase
A This is the moment of the actual trauma. Actions taken during this phase are aimed at minimizing injury as the result
of the trauma.
Q7 Post Event Phase
A This deals with the outcome of the traumatic event. Obviously the worst possible outcome of a traumatic event is
death of a patient.
Q8 First Phase of Death
A Occurs within first few minutes and up to an hour after an incident. Many of these deaths occur immediately or within
seconds after the traumatic injury.
Q9 The Second Phase of Death
PHTLS Pre & Post 1
, A Occurs within the first few hours of an incident. These deaths can often be prevented by good prehospital care and
hospital care.
Q10 The Third Phase of Death
A This occurs several days to several weeks after the incident. These deaths are usually caused by multiple organ
failure. Recent studies show that this phase is being eliminated by modern trauma and critical care.
Q11 Shock
A Shock is a state of change in cellular function from aerobic metabolism to anaerobic metabolism secondary to
hypoperfusion pf the tissue cells.
Q12 intravascular fluid
A Fluid inside the vessels
Q13 intracellular fluid
A Fluid inside the cells
Q14 Interstitial Fluid
A Fluid between the cells and the vessels
Q15 Aerobic Metabolism
A Cells maintain their normal metabolic functions by utilizing an energy source known as Adeonosine
Triphosphate(ATP)
Q16 Anaerobic Metabolism
A Metabolism that takes place in the absence of oxygen; the principle by product is lactic acid. This is the "back up"
source of power, cannot be sustained for too long.
Q17 The Fick Principle
A Is a description of the components necessary for oxygenation of the cells in the body. 1) On-loading of oxygen to
RBC's in the lung 2) Delivery of RBC's to tissue cells 3) Off-loafing of oxygen from RBC's to tissue cells
Q18 Hypovolemic Shock
A Primarily hemorrhagic in the trauma patient, related to loss of circulating blood cells and fluid volume with
oxygen-carrying capacity. Most common cause of shock in trauma patients.
Q19 Distributive Shock
