3. A 22-year-old man is brought to the emergency room after falling from a horse. He is awaiting transfer to
another facility. He has a chest contusion and a non-displaced femur fracture. He is in spinal motion restriction
with a cervical collar and long backboard. He has worsening respiratory distress and hypoxemia requiring

B. Add additional downward pressure on the face mask once it is sealed.
C. Use a jaw thrust technique in place of neck extension.
D. Increase the tidal volume with each manual assisted breath. CORRECT ANSWER C
4. Which of the following anatomic features is most likely to contribute to difficulty in maintaining a patent
airway in a supine patient?
A. Edentulous mandible
B. Posteriorly displaced tongue
C. Deviated nasal septum
D. Anteriorly displaced thyroid cartilage CORRECT ANSWER 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 during inspiration occurs only with upper airway obstruction
, B. Chest rise with inspiration indicates an adequate tidal volume
C. Unilateral absent breath sounds on auscultation is a tension pneumothorax
D. Complete airway obstruction is likely when chest retraction and movement is present, but there are no breath
sounds CORRECT ANSWER D
6. An 82-year-old man who awoke with chest pain in the morning is being evaluated in the emergency
department. He is alert and oriented. Shortly after being placed on a cardiac monitor in normal sinus rhythm with

A. Do not initiate treatment because, due to his age, he probably has a do-not-resuscitate order on file.
B. Attempt to contact the family before treating to discuss the level of inter- vention.
C. Start cardiopulmonary resuscitation while preparing to defibrillate.
D. Start bag-mask-valve ventilation while preparing to intubate. CORRECT ANSWER C

B. To reverse sudden cardiac death in a patient who is in the palliative care unit
C. To prolong the life of a patient who has a do-not-resuscitate order on file to allow time for family to arrive

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