[B]

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.

Question 2

Anti-infectives are grouped into pharmacological classes by their:
 
  1. staining ability.
  2. size or shape.
  3. sensitivity.
  4. mechanism of action.

Answer to Question 1

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.

Answer to Question 2

Correct Answer: 4
Rationale 1: Antibiotics are not classified according to their staining ability.
Rationale 2: Antibiotics are not classified according to their size or shape.
Rationale 3: Antibiotics are not classified according to their sensitivity.
Rationale 4: Antibiotics are grouped into classes by their mechanism of action, susceptible organisms, and chemical structure.
Global Rationale: Pharmacologic classes are used to group anti-infectives by their mechanism of action. Like chemical classes, placing an antibiotic into a pharmacologic class allows the nurse to develop a mental framework on which to organize these medications and to predict similar actions and adverse effects.

YES! Correct, THANKS for helping me on my review
