Which antibiotic option is listed for septic shock management?

• A. Vancomycin
• B. Doxycycline
• C. Azithromycin
• D. Imipenem

Answer: (D)

In septic shock, start broad-spectrum antibiotics right away to cover the most likely and dangerous pathogens, including Gram-negative bacteria and anaerobes, until culture results guide narrowing. Imipenem is a carbapenem with very broad activity against many Gram-positive cocci, a wide range of Gram-negative rods (including common Enterobacterales and often Pseudomonas), and anaerobes. This wide coverage makes it a strong empiric choice for septic shock, where missing a pathogen could be fatal. The other options are narrower in scope: vancomycin targets Gram-positive organisms (notably MRSA) but lacks reliable Gram-negative and anaerobic coverage by itself; doxycycline and azithromycin cover some Gram-positive organisms and atypicals but do not provide the robust Gram-negative/anaerobic coverage needed in septic shock.
