Which of the following is an early recognition sign of sepsis and the corresponding initial action?

• A. Fever or hypothermia, tachycardia, tachypnea, altered mental status, leukocytosis or leukopenia; actions: alert clinician, start sepsis protocol
• B. Hypertension, bradycardia, and dry mucous membranes
• C. Nausea and vomiting without fever
• D. Fever or hypothermia, tachycardia, tachypnea, altered mental status, leukocytosis or leukopenia; actions: alert clinician, start sepsis protocol, obtain cultures, administer antibiotics as ordered, begin fluid resuscitation.

Answer: (D)

Recognizing sepsis early hinges on noticing a systemic inflammatory response to infection: fever or hypothermia, fast heart rate, fast breathing, changes in mental status, and abnormal white blood cell counts. When these signs appear with suspected infection, the best immediate action is to mobilize a full response right away. Alert the clinician and begin sepsis care without delay: obtain cultures to identify the source, start broad-spectrum antibiotics as ordered, and begin fluid resuscitation to support blood pressure and tissue perfusion. This combination addresses both the infection and the body's response, which is essential to prevent progression to septic shock.

Other options miss pieces that are critical in the early management: one may note the signs but omit obtaining cultures, starting antibiotics, or giving fluids; another may present non-sepsis vital signs; and another may list the signs plus only partial actions. The most effective approach is the complete bundle of recognizing the signs and initiating all key initial actions.
