4-24.  Electrical  and  electronic 4-25. 4-26. 4-27. equipment pose significant injury hazards.  Authorized  means  to reduce  this  hazard  include 1. repairing frayed cords with electrical  tape  to  prevent shocks 2. informing the staff of defective   equipment 3. having medical repair perform electrical safety checks on all  new  equipment 4. using  only  two-prong, nongrounded electrical plugs Skin contact berns can be caused by icebags or hypothermia blankets. 1. True 2. False One of the most frequent causes of fire is the careless handling of tobacco products. To serve as an  effective  safety  measure, smoking  regulations  must  be enforced  by  which  staff personnel? 1. Hospital  security 2. Director  of  Administrative Services 3. Area  supervisors 4. All  staff  personnel Documentation  and  analysis  of  all accidents and injuries^- is provided  to 1. forestall  negligence  or malpractice  suits 2. identify  and  punish  the responsible  person(s) 3. identify  and  correct  safety deficiencies 4. all of the above 4-28.    Environmental hygiene is directed toward  producing  a  healthy environment and includes such practices as maintaining unit cleanliness  and 1. providing  for  adequate ventilation 2. limiting  noise  levels 3. proper disposal of soiled articles 4. all of the above To  answer  items  4-29  through  4-32, select  from  column  B  the  situational element that most closely matches the chain of infection link in column A as it  applies  to  the  following  scenario. A corpsman assists a medical officer to perform incision and drainage of a furuncle on a patient’s leg. After the I&D procedure, the corpsman changes  a  postsurgical  abdominal dressing on the same patient. A few days later, the surgical wound appears red and swollen and a culture reveals a  significant  staphylococcal infection. A.
