Chapter 19
1. Your patient was a passenger in a motor vehicle crash yesterday and suffered an
open fracture of the femur. His condition was stable until an hour ago, when he
began to complain of shortness of breath. His heart rate is 104 beats/min,
respiratory rate is 30 breaths/min, BP is 90/60 mm Hg, and temperature is now 38.4°
C. You suspect that he:
A. has a fat embolism.
B. has developed metabolic acidosis.
C. is developing systemic inflammatory response syndrome (SIRS).
D. is experiencing early multiple organ dysfunction syndrome (MODS).
ANS: A
Rationale: These are classic signs and symptoms of a fat embolism. The history of a longbone fracture adds to the evidence of a fat embolism. The patient may develop
metabolic acidosis associated with poor oxygenation from the fat emboli. SIRS possibly
progressing to MODS would also be a consequence of the fat emboli
2. Poor patient outcomes after a traumatic injury are associated with:
A. chest tube placement for treatment of a hemothorax.
B. immediate decompression of a tension pneumothorax.
C. massive transfusions of blood products.
D. intraosseous cannulation for intravenous fluid administration.
Ans:C
Rationale: Current evidence suggests that patients receiving massive blood transfusions
have poorer outcomes. Although a chest tube may be necessary in the treatment of
trauma patients, it is not associated with poor patient outcomes. Immediate
decompression of a tension pneumothorax is also not associated with poor patient
outcomes. Intraosseous cannulation for intravenous fluid administration has not been
shown to have adverse patient outcomes.
3. Which condition is a common cause of death after chest trauma?
A. Cardiac tamponade
B. Flail chest
C. Hemothorax
D. Pulmonary contusion
ANS: D
Rationale: Pulmonary contusion as a result of blunt chest trauma increases the risk for
development of pneumonia, acute lung injury, and/or ARDS. Cardiac tamponade is life
threatening if untreated, but it is not a common complication after blunt chest trauma.
Flail chest and hemothorax may result with blunt chest trauma, but they are not
common causes of death.

Prima service, snelle afhandeling. Ik ga hiervan gebruik maken gedurende mijn hele studie.
Knoowy is heel handig om te gebruiken en je vind snel het materiaal dat je nodig hebt.
Soms koop ik meerdere samenvattingen over 1 boek. Dit helpt mij als ik onvoldoende tijd heb om het hele boek te lezen en zelf geen samenvatting kan maken.
Jullie website is top! Het heeft me al veel geholpen. Zeker omdat ik thuis studeer!
Het uploaden en verkopen van mijn documenten verloopt altijd super vlot, alles word eigenlijk al door Knoowy geregeld! Leuk dat medestudenten ook iets aan mijn documenten hebben!
Weer een goede ervaring met Knoowy. Makkelijk en snel een nette samenvatting.
Knoowy is voor ons een extra verkoopkanaal en biedt de mogelijkheid samenvattingen online te verkopen.
Knoowy is voor mij de perfecte service om een centje bij te verdienen! Die samenvattingen moet ik sowieso maken, dus waarom ze niet uploaden en wat bijverdienen?
