Q

Universal vs Standard precautions

Standard

A

Used for isolation and precautions in hospitals

  • Uses universal and Body Substance Isolation
  • Considered the best way to control nosocomial infections
  • Standard precautions pertain to ALL bodily fluids, secretions and excretions

  • Several organizations are involved with these: CDC, OSHA,EPA, State Health Department
  • Each hospital/medical setting will have policies in place that must be followed
25

26
Q

Isolation precautions

A
  • Depends on method of transmission
