Prior to administration, the client asks the nurse how telithromycin (Ketek) works in treating a lower respiratory tract infection. Which nurse response would be correct?

1. Ketek blocks bacterial protein synthesis by binding to two different sites on the 50S ribosomal subunit.

2. Ketek alters the DNA of bacteria, rendering the microorganism inactive.

3. Ketek decreases bacterial folic acid synthesis, stopping the growth of the microorganisms.

4. Ketek inhibits the protein synthesis of the bacterial cell wall and stops the growth of the microorganism.
