PVL Staphylococcal Pneumonia — SCE Infectious Diseases MCQ

Correct answer: C — Add a protein-synthesis inhibitor such as clindamycin or linezolid alongside active anti-staphylococcal therapy with review after review with follow-up

The best answer is “Add a protein-synthesis inhibitor such as clindamycin or linezolid alongside active anti-staphylococcal therapy with review after review with follow-up”. Protein-synthesis inhibition can suppress exotoxin production, while definitive therapy must still cover the organism and provide organ support. “Continue a beta-lactam alone because PVL has no therapeutic relevance” is less appropriate because it conflicts with the decisive clinical feature or cited guidance. “Add gentamicin solely for toxin suppression” is less appropriate because it conflicts with the decisive clinical feature or cited guidance. “Use rifampicin monotherapy” is less appropriate because it conflicts with the decisive clinical feature or cited guidance. “Stop antibacterial therapy and give corticosteroid alone” is less appropriate because it conflicts with the decisive clinical feature or cited guidance.
