The nurse is setting up an intravenous infusion pump to administer a dose of vancomycin [Vancocin] to a patient. What is the fastest rate at which the drug may be infused?
60 minutes
30 minutes
90 minutes
45 minutes
The Correct Answer is A
Vancomycin is often administered over at least 60 minutes to reduce the risk of infusion-related reactions, such as "Red Man Syndrome," which is characterized by flushing, rash, and itching. This reaction is caused by the rapid infusion of vancomycin, leading to the release of histamine.

Correct Answer is A
Explanation
A. "Tetracycline inhibits protein synthesis."
Tetracycline inhibits bacterial protein synthesis by binding to the bacterial ribosomes, which are crucial for making proteins. This disruption in protein synthesis prevents bacterial growth and replication.
B. "Tetracycline blocks RNA synthesis."
Tetracycline primarily affects protein synthesis, not RNA synthesis. It binds to the 30S subunit of the bacterial ribosome and disrupts the translation process.
C. "Tetracycline degrades the bacterial cell wall."
Tetracycline does not target the bacterial cell wall. Drugs like penicillin and cephalosporins work by disrupting cell wall synthesis, but tetracycline operates differently by inhibiting protein synthesis.
D. "Tetracycline binds to magnesium ions."
Tetracycline does not specifically bind to magnesium ions. Its primary mode of action involves binding to the bacterial ribosome, as mentioned in the first correct statement.
