QUESTION 1: What is the official definition of sepsis according to the
Sepsis-3 consensus guidelines?
• A) Systemic inflammatory response syndrome (SIRS) triggered by
any confirmed bacterial infection
• B) Life-threatening organ dysfunction caused by a dysregulated
host response to infection
• C) The presence of viable bacteria multiplying rapidly within the
blood stream
• D) Refractory hypotension that fails to respond to intravenous
fluid resuscitation
Correct Answer: B Rationale: Sepsis-3 defines sepsis as life-threatening
organ dysfunction caused by a dysregulated host response to infection,
representing a shift from the older SIRS-based definitions.
QUESTION 2: Which clinical screening tool is recommended by Sepsis-3
guidelines to quickly identify patients outside the ICU who are at high
risk for poor outcomes from sepsis?
• A) Glasgow Coma Scale (GCS)
• B) Quick Sequential Organ Failure Assessment (qSOFA)
• C) Braden Scale for Pressure Ulcer Risk
• D) National Institutes of Health Stroke Scale (NIHSS)
,Correct Answer: B Rationale: qSOFA evaluates three parameters
(altered mental status, systolic blood pressure <= 100 mmHg, and
respiratory rate >= 22 breaths/min) to flag non-ICU patients at higher
risk of sepsis-related mortality.
QUESTION 3: Septic shock is clinically defined by which specific
pathophysiological and hemodynamic criteria?
• A) Persistent hypotension requiring vasopressors to maintain
Mean Arterial Pressure (MAP) >= 65 mmHg AND serum lactate > 2
mmol/L despite adequate fluid resuscitation
• B) A body temperature exceeding 39.0°C and a white blood cell
count over 15,000/mcL
• C) Isolated tachycardia and tachypnea without blood pressure
changes
• D) Mild oliguria that resolves after a single 500 mL fluid bolus
Correct Answer: A Rationale: Septic shock requires both persistent
hypotension necessitating vasopressors to keep MAP >= 65 mmHg and
a cellular metabolism marker (lactate > 2 mmol/L) despite fluid
resuscitation.
QUESTION 4: According to the Surviving Sepsis Campaign (SSC) 1-hour
bundle, within what timeframe from time of presentation must initial
resuscitation actions be initiated?
• A) Within 1 hour
• B) Within 3 hours
• C) Within 6 hours
, • D) Within 24 hours
Correct Answer: A Rationale: The SSC bundle mandates that key
diagnostic and therapeutic actions—such as measuring lactate,
obtaining blood cultures, administering broad-spectrum antibiotics, and
starting fluid resuscitation—begin immediately and be completed
within 1 hour.
QUESTION 5: Why is measuring a serum lactate level an essential
component of the initial sepsis resuscitation bundle?
• A) Elevated lactate acts as a surrogate marker of tissue
hypoperfusion, cellular dysoxia, and anaerobic metabolism
resulting from distributive shock.
• B) Lactate levels determine the exact type of bacterial organism
causing the infection.
• C) Lactate replaces the need for continuous blood pressure
monitoring.
• D) Lactate predicts kidney stone formation.
Correct Answer: A Rationale: High lactate levels indicate cellular hypoxia
and anaerobic glycolysis due to microvascular dysfunction and
inadequate tissue perfusion in sepsis.
QUESTION 6: When should blood cultures be obtained in relation to
antibiotic administration in a patient presenting with suspected sepsis?
• A) At least two sets of blood cultures (aerobic and anaerobic)
drawn prior to initiating antimicrobial therapy, provided this does
not cause substantial delay (> 45 minutes).
• B) Exactly 24 hours after antibiotics have been finished.
