Select one:
a. His pulse pressure will be widened.
b. His urinary output will be at the lower limits of normal.
c. He will have tachycardia, but no change in his systolic blood pressure.
d. An ABG would demonstrate a base deficit between -6 and -10 mEq/L
e. His systolic blood pressure will be maintained with an elevated
diastolic pressure. - answersd.
An ABG would demonstrate a base deficit between -6 and -10 mEq/L
The physiologic hypervolemia of pregnancy has clinical significance in the
management of the severely injured, gravid woman by:
Select one:
a. reducing the need for
blood transfusion
1
,b. resulting in an elevated
haematocrit
c. complicating the management of closed head injury
d. reducing the volume of crystalloid required for resuscitation
e. increasing the volume of blood loss to produce maternal hypotension -
answerse.
increasing the volume of blood loss to produce maternal hypotension
The best assessment of fluid resuscitation of the adult burn patient is:
Select one:
a.
Urine output of 0.5 mL/kg/hr
b.
normalization of blood pressure
c.
normalization of the heart rate
d.
measuring a normal central venous pressure
e.
providing 4 mL/kg/percent body burn/24 hours of crystalloid fluid -
answersa.
2
,Urine output of 0.5 mL/kg/hr
The diagnosis of shock must include:
Select one:
a.
hypoxemia
b.
acidosis
c.
hypotension
d. increased vascular
resistance
e.
evidence of inadequate organ perfusion - answerse.
evidence of inadequate organ perfusion
A 22-year-old man is hypotensive and tachycardic after a shotgun wound
to the left shoulder. His blood pressure is initially 80/40 mm Hg. After
initial fluid resuscitation his blood pressure increases to 122/84 mm Hg.
His heart rate is now 100 beats per minute and his respiratory rate is 28
breaths per minute. A tube thoracostomy is performed for decreased left
chest breath sounds with the return of a small amount of blood and no air
leak. After chest tube insertion, the most appropriate next step is:
3
, Select one:
a.
reexamine the chest
b.
perform an aortogram
c.
obtain a CT scan of the chest
d.
obtain arterial blood gas
analyses
e.
perform transesophageal echocardiography - answersA) Reexamine the
chest
A construction worker falls two stories from a building and sustains
bilateral calcaneal fractures. In the emergency department, he is alert,
vital signs are normal, and he is complaining of severe pain in both heels
and his lower back. Lower extremity pulses are strong and there is no
other deformity. The suspected diagnosis is most likely to be confirmed
by:
Select one:
a.
angiography
