A 72-year-old patient with pneumonia develops hypotension (BP 80/50 mmHg), tachycardia, and altered mental status. Lactate is 4.5 mmol/L. What is the most immediate next step in management after recognizing sepsis and septic shock?

The correct answer to the question "A 72-year-old patient with pneumonia develops hypotension (BP 80/50 mmHg), tachycardia, and altered mental status. Lactate is 4.5 mmol/L.
