Q

culture and sensitivity (C&S) study should be done to specify the -

A

exact organism and the medication that will be effective before antibiotics are prescribed

17
Q

identifying bacteria:

A
  • Culture and Sensitivity (C&S)
  • Sample of infectious material from skin, Resp Tract, Urinary tract etc obtained
  • Placed on culture plate (24-48) hours
  • Variety of antibiotics placed on plate
  • Control of:
  • -no growth = sensitive
  • -growth = resistant
18
Q

nursing interventions

A
  • Assess for results of a C&S to ensure one has been completed before starting on an antibiotic
  • Instruct patient to take all of the medication even if symptoms subside to prevent recurrence of the infection
  • Failure to complete the prescribed regimen promotes bacterial resistance
19
Q
