Actions of Agents
ADN 110/cohort 13
4
Cell wall protein is destroyed; cell death occurs
Cell membrane permeability increases and vital contents leak out; cell death occurs
Metabolism is disrupted; cell death occursCell components become oxidized; cell death
occurs

Antimicrobial Therapy
ADN 110/cohort 13
7
Original antimicrobials: derived from microorganisms
Newer agents: chemically synthesized Prevent infections..

Overview
Antimicrobial therapy = antibiotic therapyMedication therapy to treat infections
Sources of Infection Bacteria Viruses fungi
Natural or synthetic Selective toxicity
Continual creation of new antimicrobials Changes in DNA or micro-organisms
Supra-infection Normal flora killed by use of an antibiotic

Administering Antimicrobial Agents
ADN 110/cohort 13
13
Consider the following: Location of the infecting organism in the body Status of the client’s organ function Age of the client Pregnancy and/or lactation Likelihood of developing organisms resistant to the
antimicrobial agent

Overuse
ADN 110/cohort 13
14
Overuse of antimicrobial agents can lead to the development of severely resistant organisms. Promoted the development of organisms that are not
affected by any of the available therapies
