An antipseudomonal, cephalosporin, beta-lactam/beta-lactamase inhibitor, or carbapenems plus an aminoglycoside, or antipseudomonal fluoroquinolone plus anti-MRSA antibiotic (linezolid or vancomycin) is the recommended initial combination for late-onset and for VAP in high-risk patients.
D. Incorrect response: See explanation C
