8-9. 8-10. 8-11. 8-12. If  you  discover  a  tick  feeding on you body, you should 1. remove  it  with  tweezers  or forceps 2. coat  it  with  Vaseline  and let it drop off by itself 3. burn it off with a lit match or  cigarettes 4. apply  an  antiseptic  and ignore it; it will leave in a few hours The  recommended  method  of  control for an infestation of nice is 1. poisoning 2. trapping 3. fumigation 4. wire  screening  in  all buildings The best poisoned bait for the Norway rat in 1. fish orF meat 2. fruits or melons 3. sweet  potatoes 4. bread or oatmeal Although spring traps can be effective without bait, they are more  effective  when  baited. Preferred  baits  may  include  all of the following EXCEPT 1. cheese 2. coconut 3. bacon  rind 4. fresh  raw  vegetables 8-13. Even though most naval shore activities receive water from a municipal  source,  the  Navy  is responsible  for 1. ensuring  the  municipal  water is  chlorinated  before  receipt 2. the  integrity  of  the  base water distribution system 3. ensuring  that  the  water received  is  pure 4. the  disinfection  of  all  water received 8-14.  One  step  in  disinfecting  water in a canteen is to 1. ensure the threads of the canteen  neck  are  rinsed  with treated  water 2. boil  the  water  before treatment 3. boil the water after treatment 4. filter  the  water  through  a clean  cloth,  i.e.  ,  cheese cloth 8-15. Shipboard water distilled from a suspected  contaminated  source must be chlorinated to ___ ppm after  39  minutes  contact  time. 1. 0.02 2. 0.2 3. 2.0 4. 20.0 8-16. After a 24 hour incubation, you note  eight  reddish  hued bacterial  colonies  on  a  water sample you are testing. You should 1. suspect  fecal  contamination and  institute  corrective action   immediately 2. incubate another sample from the same source. If the results  are  the  same,  submit another  sample  for  outside testing 3. log the results as background  growth:  no  other action  is  required 4. increase the FAC to 2.0 to 3.0 ppm 8-17. One of the differences that may determine whether to use a chemical  or  biological  agent  in warfare is that 1. biological  agents  are universally   effective against  humans  and  constant in their effect 2. effective  immunity  against chemical  agents  is  readily available 3. immediate effects are produced  with  chemical agents 4. there  are  significant difference 49
