The nurse caring for a client with an infection knows a contributing factor to the development of drug resistance is the presence of bacterial genetic errors called:
1. plasmids.
2. mutations.
3. conjugates.
4. duplications.
Correct Answer: 2
Rationale 1: Plasmids are small pieces of DNA.
Rationale 2: Genetic errors are mutations.
Rationale 3: Conjugation is a part of transcription.
Rationale 4: Duplication is the repeating of the genetic code, and it is a normal process.
Global Rationale: During exponential division, bacteria make frequent errors, or mutations, while duplicating their genetic code. These mutations, which occur spontaneously and randomly, occasionally result in a change in physiology that gives a bacterial cell a reproductive advantage over its neighbors.
