Which statement best describes vancomycin's clinical indication?

• A. Indications: severe infection most likely by MRSA.
• B. Treats viral infections.
• C. Indicated for mild skin infections.
• D. Used for pain control.

Answer: (A)

Vancomycin is a potent antibiotic primarily used for serious Gram-positive infections, especially those caused by MRSA. This makes the statement describing its indication as a severe infection most likely due to MRSA the best choice, because vancomycin is chosen when MRSA is suspected or confirmed or when resistance to other antibiotics is a concern. It is not used to treat viral infections, not typically indicated for mild skin infections (where less broad agents are appropriate), and it is not a medication for pain control. In practice, vancomycin is given IV for systemic infections and IV monitoring guides dosing to balance effectiveness with potential toxicity.
