A 68-year-old client is admitted to the emergency department with suspected sepsis from a urinary tract source. Vital signs: temperature 39.2°C, heart rate 122/min, respiratory rate 26/min, blood pressure 88/52 mm Hg, SpO2 94% on room air. Which interventions should the nurse anticipate initiating immediately as part of evidence-based sepsis management? Select all that apply.

Explanation
Evidence-based immediate sepsis management includes measuring lactate (Choice 2), obtaining blood cultures before antibiotics if this does not substantially delay antimicrobial therapy (Choice 3), administering broad-spectrum IV antimicrobials immediately and ideally within 1 hour for possible septic shock or a high likelihood of sepsis (Choice 6), and beginning rapid 30 mL/kg crystalloid resuscitation for hypotension or lactate ≥ 4 mmol/L (Choice 4). Current Surviving Sepsis Campaign guidance recommends delivering at least 30 mL/kg within the first 3 hours for sepsis-induced hypoperfusion or septic shock while treatment and resuscitation begin immediately. Withholding fluids until the next provider round (Choice 1) and limiting urine-output measurement to once per shift (Choice 5) are unsafe in this hypotensive client.
Sepsis 1-Hour Bundle "Lactate · Cultures · Antibiotics · Fluids · Pressors" — completed within 60 minutes of recognition.
Order of Action 1. Lactate + cultures drawn first 2. Broad-spectrum antibiotics within 1 hour — every hour delay = ↑ mortality 3. 30 mL/kg crystalloid rapid bolus if hypotensive or lactate ≥ 4 4. Vasopressors during/after fluids to keep MAP ≥ 65 mm Hg

Caution Cultures should not delay antibiotics >45 min. Hourly urine output is required to track end-organ perfusion.
Scenario68 y.o. client, suspected urosepsis. T 39.2°C · HR 122 · RR 26 · BP 88/52 · SpO2 94% RA · WBC 18,500 · lactate pending.

Red FlagLactate ≥ 4 mmol/L OR MAP < 65 after fluids → vasopressors and ICU transfer.
Surviving Sepsis Campaign 1-hour bundle — Evidence-based sepsis care set: measure lactate, obtain blood cultures, administer broad-spectrum antibiotics, begin 30 mL/kg crystalloid for hypotension or lactate ≥ 4, apply vasopressors to maintain MAP ≥ 65. Each hour of antibiotic delay increases mortality.
Lactate as a perfusion marker — Serum lactate ≥ 2 mmol/L suggests tissue hypoperfusion. ≥ 4 mmol/L meets the threshold for aggressive 30 mL/kg crystalloid resuscitation. Trend lactate q2-4h to gauge response.
Mean arterial pressure (MAP) goal — In septic shock, target MAP ≥ 65 mm Hg via fluids first then norepinephrine as first-line vasopressor. MAP = (SBP + 2×DBP) / 3. MAP < 65 indicates inadequate organ perfusion.
