A nurse is instructing a colleague on how an antimicrobial produces a therapeutic effect. What should be included in the nurse's teaching?
The first drugs used to treat infections date back to the 17th century.
Fluoroquinolones interfere with the growth and development of the bacteria cell wall.
Selective toxicity determines the appropriate drug dosage needed.
Penicillin interferes with synthesis of the bacteria cell wall.
The Correct Answer is D
A. While historical context is useful, the development of antimicrobials primarily began in the early 20th century, notably with penicillin discovered by Alexander Fleming in 1928.
B. This statement is incorrect; fluoroquinolones primarily inhibit bacterial DNA synthesis rather than directly affecting the cell wall.
C. Selective toxicity is a principle of antimicrobial action but does not directly explain how a specific antimicrobial works therapeutically.
D. Penicillin specifically interferes with the synthesis of the bacterial cell wall, leading to cell lysis and death of the bacteria, which is a fundamental mechanism of action for this antibiotic.
