1. A 75-year-old female patient, was admitted to the intensive care unit (ICU) following a severe slip and fall accident in the bathroom. She sustained multiple fractures, required mechanical ventilation, and underwent several surgical procedures. During her ICU stay, she developed a fever and signs of sepsis.
On Day 1, the patient was stable post-surgery but developed a fever of 39°C (102.2°F) and a leukocytosis with a white blood cell count of 18,000/µL.
Blood cultures were taken, and empiric broad-spectrum antibiotics (piperacillin/tazobactam and vancomycin) were initiated.
On third day, the patient's condition worsened with increased respiratory distress, and new infiltrates were noted on chest X-ray.
Blood culture results returned positive for Klebsiella pneumoniae, and additional cultures were taken from the endotracheal tube, urine, and surgical wounds.
Laboratory Results
Blood Culture: Klebsiella pneumoniae
Endotracheal Culture: Pseudomonas aeruginosa
Urine Culture: Enterococcus faecium.
Surgical Wound Culture: Staphylococcus aureus.
The patient's respiratory status began to stabilize with improved oxygenation.
Repeat cultures showed no growth of Klebsiella pneumoniae and reduced colony counts of Pseudomonas aeruginosa and MRSA.
The patient was transferred to a step-down unit with a tailored antibiotic regimen and close monitoring for potential relapse or secondary infections.
Which of the following antibiotic is a common initial empiric antibiotic therapy given to the patient?
A. Colistin and meropenem
