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