The nurse attends a class on preventing resistance to anti-infectives and learns that the critical concept in preventing the development of resistant strains of microbes is what?
A) Exposure of pathogens to an antimicrobial agent without cellular death
B) Drug dosages that are below a therapeutic level
C) The duration of drug use
D) Frequency of drug ingestion
C
Feedback:
Exposure of pathogens to an antimicrobial agent without cellular death leads to the development of resistance so it is important to limit the use of these agents to treat pathogens with a known sensitivity to the drug being used. Drug dosages are also important in preventing the development of resistance. However, the duration of drug use is critical to ensure that microbes are completely eliminated and not given the chance to grow and develop resistant strains. It is hard to convince patients that they must always complete the entire course of antimicrobial agents when they begin to "feel better," because stopping early favors the emergence of drug-resistant strains.
