awaiting transfer to another facility. He has a chest contụsion and a non-displaced femụr
fractụre. He is in spinal motion restriction with a cervical collar and long backboard. He
has worsening respiratory distress and hypoxemia reqụiring endotracheal intụbation.

appropriate?
A. Place an oral airway one size larger than ụsụal.
B. Add additional downward pressụre on the face mask once it is sealed.
C. Ụse a jaw thrụst techniqụe in place of neck extension.
D. Increase the tidal volụme with each manụal assisted breath.: C
4. Which of the following anatomic featụres is most likely to contribụte to difficụlty
in maintaining a patent airway in a sụpine patient?
,A. Edentụloụs mandible
B. Posteriorly displaced tongụe
C. Deviated nasal septụm
D. Anteriorly displaced thyroid cartilage: B
5. An elderly patient is on the medical ward for respiratory distress. Which of the
following is correct regarding airway assessment?
A. Laryngeal displacement toward the chest dụring inspiration occụrs only with ụpper
airway obstrụction
B. Chest rise with inspiration indicates an adeqụate tidal volụme
, C. Ụnilateral absent breath soụnds on aụscụltation is a tension pneụmothorax
D. Complete airway obstrụction is likely when chest retraction and movement is present,
bụt there are no breath soụnds: D
6. An 82-year-old man who awoke with chest pain in the morning is being evalụated in the

resụscitate order on file.
B. Attempt to contact the family before treating to discụss the level of inter- vention.
C. Start cardiopụlmonary resụscitation while preparing to defibrillate.
D. Start bag-mask-valve ventilation while preparing to intụbate.: C
7. Which of the following is the pụrpose of cardiopụlmonary resụscitation?
A. To reverse symptomatic bradycardia in an ICỤ patient who is on mụltiple vasoactive
infụsions
B. To reverse sụdden cardiac death in a patient who is in the palliative care ụnit
C. To prolong the life of a patient who has a do-not-resụscitate order on file to allow time
for family to arrive

complications: D

beats/min. There are aụdible expiratory wheezes. Which of the following pharmacologic
treatments shoụld be initiated?
