2-39.  Artificial  ventilation  to  a patient with a badly displaced mandibular fracture is best given 1. by mouth-to-mouth ventilation 2. by mouth-to-nose ventilation 3. with an oxygen mask 4. by the back-pressure arm-lift method 2-40. The major problem you should anticipate when relieving gastric distention is 1.    reduced lung volume 2.    internal  bleeding 3.    vomiting 4.   cardiac  arrest 2-41.   When ventilating an infant using the mouth-to-mask method, an airtight seal is best obtained by 1.   fitting the apex of the mask over the bridge of the nose 2.   fitting the apex of the mask over  the  chin 3.   compressing the collar of an adult  mask 4. attaching an oxygen line 2-42. One of the distinct advantages of using an esophageal obturator airway  is 1. it  can  be  inserted  directly into  the  trachea 2. the  tracheal-bronchial  tree can  be  readily  suctioned 3. it  cannot  be  misplaced 4. it  helps  prevent  vomiting 2-43. Cricothyroidotomy is the process or technique of 1. hyperextending  the  neck 2. creating an opening to the trachea 3. auctioning  the  trachea 4. inserting an esophageal obturator airway 2-44. The best place to find the pulse of an unconscious patient is the _______artery. 1.  pulmonary 2. carotid 3. apical 4. radial 2-45. 2-46. 2-47. 2-48. 2-49. 2-50. 2-51. A fracture of the xiphoid tip of the  sternum  during  CPR  may  cause significant  damage  to  the 1. rib cage 2. lungs 3. spleen 4. liver In one-rescuer CPR, the proper compression to ventilation ratio is 1. 15 to 2 2. 2 to 15 3. 1 to 5 4. 5 to 1 The first step in preparing to perform CPR is to 1.    check vital signs 2.    determine   unconsciousness 3.    locate the sternum 4.    establish  a  patent  airway When  performing  CPR  on  an  adult, the  depth  of  compressions  is 1. 0.5 to 1.0 inch 2. 1.0 to 2.0 inches 3. 1.5 to 2.0 inches 4. 1.5 to 2.5 inches An avulsion injury is a 1. traumatic  removal  of  a  limb 2. piercing  injury  that    closes over 3. clean  surgical  cut 4. traumatic  removal  of  tissue Blood that is bright red and flowing in a steady stream is probably 1. capillary 2. from   a    deep vein 3. from a deep artery 4. from  a   surface vein In most situations, the best and first  method  to  control  external hemorrhage  is 1. direct  pressure 2. pressure  point 3. elevation 4. tourniquet 10
