The nurse is caring for a patient receiving penicillin. The nurse knows this type of antibiotic works by what mechanism?
A) Inhibiting growth and development of the organism
B) Inhibiting protein synthesis
C) Inhibiting cell wall biosynthesis
D) Stimulating bacterial reproduction
C
Feedback:
Some anti-infectives interfere with biosynthesis of the bacterial cell wall. Because bacterial cells have a slightly different composition than human cells, this is an effective way to destroy the bacteria without interfering with the host (see Box 8.2). The penicillins work in this way. The sulfonamides inhibit growth and development of the organism's cells. Aminoglycosides, macrolides, and chloramphenicol interfere with protein synthesis. Fluoroquinolones interfere with synthesis of deoxyribonucleic acid, resulting in the inability to reproduce.
