3-58.  The  most  common  psychiatric emergency is probably the suicide gesture  or  attempt.  Basic treatment consists of all of the following  EXCEPT 1. a  calm  and  understanding presence 2. leaving  the  victim  alone  to reflect  on  his  or  her  actions 3. assuming  all  suicide  threats are real 4. treating   self-inflicted wounds  as  any  other  wound 3-56. During childbirth, when the baby’s  head  presents,  apply gentle  pressure  to 1. prevent an explosive delivery 2. avoid  compressing  the umbilical  cord 3. compress  the  cord  to stimulate  the  infants  vital functions 4. allow  you  time  to  suction  the mouth and nose of the infant 3-60.  The  infant’s  mouth  and  nose should  be  suctioned 1. if  spontaneous  respirations do not occur 2. when the chin clears the vaginal  canal 3. after the child has completely  emerged 4. after  clamping  and  cutting the  umbilical  cord 3-61. Emergency first aid treatment for a  prolapsed  cord  during childbirth includes all of the following  EXCEPT 1. decompressing  the  cord  as much  as  possible 2. giving  oxygen  therapy 3. placing  the  mother  in  the shock  position 4. clamping  and  cutting  the umbilical  cord  when  it presents 3-62. The oxygen breathing apparatus (OBA) is a valuable adjunct in rescue operations because it 1. can  be  connected  directly  to an  external  air  source 2. provides  positive  pressure ventilation  for  the  wearer 3. neutralizes or filters toxic gasses 4. generates  its  own  oxygen 3-63.    When should an oxygen source be 3-64. 3-65. 3-66. 3-67. 3-68. connected to an air line mask? 1. When  entering  a  carbon dioxide  filled  compartment or void 2. When  entering  a  compartment or void with fuel oil vapors 3. After  the  couplings  have been cleaned of all oil or grease 4. An air line mask should never be connected to an oxygen  source The  standard  gas  mask  provides effective  protection  against 1. carbon  monoxide  and  carbon dioxide 2. low  oxygen  concentration 3. both 1 and 2 above 4. chemical  and  biological warfare  agents A  protective  asbestos  suit protects  the  wearer 1. in  steam  filled  compartment 2. against  brief  exposure  to f lame 3. from  being  scalded 4. during  prolonged  exposure  to heat When  using  a  life-line  to  raise an  unconscious  person  from  a compartment,  attach  the life-line  around 1. the waist and to the belt 2. the chest and under the arms 3. the hips and the wrists 4. the arms and legs The  moat  practical  stretcher  to use when lifting a casualty from an engine room is a/an 1. Stokes  stretcher 2. Army  litter 3. Neil  Robertson  stretcher 4. Improvised  blanket  and  line stretcher Probably  the  easiest  way  to carry  an  unconscious  person  is the 1. fireman’s  carry 2. tied-hands  crawl 3. blanket  drag 4. chair  carry 19
