Sepsis US Medical PG Practice Questions and MCQs
Question 1: A 38-year-old previously healthy woman develops septic shock from necrotizing fasciitis of the lower extremity. Despite three debridements, broad-spectrum antibiotics (vancomycin, meropenem, clindamycin), IVIG, and aggressive critical care support, she develops refractory shock requiring norepinephrine 1.2 mcg/kg/min, vasopressin 0.04 units/min, and epinephrine 0.1 mcg/kg/min. Lactate is 15 mmol/L. Surgical team recommends hemipelvectomy as last option for source control. Family is devastated. ICU team notes SOFA score of 18. Synthesize an approach to management and decision-making.
A. Transfer to ECMO center for consideration of VA-ECMO as bridge to hemipelvectomy
B. Multidisciplinary meeting with surgery, ICU, palliative care, and family to discuss realistic outcomes, quality of life, and patient values before decision (Correct Answer)
C. Continue medical management for 24 hours and proceed with hemipelvectomy only if shock improves
D. Decline surgery based on futility given SOFA score >15 and initiate comfort care
E. Proceed with hemipelvectomy immediately as only chance for survival with informed consent from family
Explanation: ***Multidisciplinary meeting with surgery, ICU, palliative care, and family to discuss realistic outcomes, quality of life, and patient values before decision***
- In high-acuity cases with refractory shock and high **SOFA scores (>15)**, shared decision-making is essential to align surgical intervention with the patient’s **goals of care**.
- This approach ensures that the **prognosis**, which carries a high risk of mortality and morbidity from **hemipelvectomy**, is transparently communicated by the entire medical team.
*Transfer to ECMO center for consideration of VA-ECMO as bridge to hemipelvectomy*
- **VA-ECMO** is generally not indicated in septic shock with refractory vasoplegia and severe multi-organ failure as it doesn't solve the **source control** issue.
- The logistics and physiological stress of a transfer in the setting of **1.2 mcg/kg/min norepinephrine** would be highly unstable and likely fatal.
*Continue medical management for 24 hours and proceed with hemipelvectomy only if shock improves*
- Delaying source control in **necrotizing fasciitis** while shock is worsening usually leads to death, as medical management alone cannot overcome the focus of infection.
- Waiting for improvement in the setting of a **lactate of 15 mmol/L** and triple vasopressors is unrealistic without definitive surgical intervention.
*Decline surgery based on futility given SOFA score >15 and initiate comfort care*
- While the **SOFA score** indicates a very high mortality risk, unilateral physician declaration of **medical futility** is ethically complex and can damage family trust.
- Comfort care should remain a possibility, but first requires a thorough **interdisciplinary discussion** to ensure legal and ethical standards are met.
*Proceed with hemipelvectomy immediately as only chance for survival with informed consent from family*
- Performing such a **mutilating surgery** without a detailed discussion of the expected **quality of life** and long-term functional loss is poor surgical practice.
- Immediate surgery without addressing the massive **operative mortality** risk ignores the patient's potential preference for a dignified death over a futile procedure.
Question 2: A 52-year-old woman with septic shock from intra-abdominal infection undergoes emergency exploratory laparotomy for perforated diverticulitis with fecal peritonitis. Surgery reveals extensive contamination requiring damage control approach. Postoperatively, she requires norepinephrine 0.8 mcg/kg/min plus vasopressin 0.04 units/min, has lactate of 8.5 mmol/L, temperature 35.2°C, INR 2.8, pH 7.18, and base deficit -12. Planned return to OR is in 48 hours. Evaluate the priority interventions to optimize outcome.
A. Immediate return to OR for definitive repair and anastomosis
B. Start therapeutic hypothermia and delay reoperation until hemodynamically stable off vasopressors
C. Initiate high-dose vasopressors to maintain MAP >75 mmHg and early enteral nutrition
D. Administer massive transfusion protocol and emergency re-exploration within 6 hours
E. Aggressive rewarming, correction of coagulopathy, ongoing resuscitation, and source control at planned reoperation (Correct Answer)
Explanation: ***Aggressive rewarming, correction of coagulopathy, ongoing resuscitation, and source control at planned reoperation***
- This patient presents with the **lethal triad** (coagulopathy, acidosis, and hypothermia) in the setting of **septic shock**, necessitating physiologic stabilization before definitive surgery.
- The gold standard for **damage control** is to stabilize the patient in the ICU by correcting **base deficit**, improving **lactate clearance**, and restoring normal temperature and coagulation parameters.
*Immediate return to OR for definitive repair and anastomosis*
- Attempting **definitive repair** or anastomosis in an unstable patient with fecal peritonitis and high-dose **vasopressor requirements** carries a prohibited risk of dehiscence and death.
- Surgery should be limited to **staged re-intervention** only after the metabolic and physiologic insults have been partially reversed.
*Start therapeutic hypothermia and delay reoperation until hemodynamically stable off vasopressors*
- **Hypothermia** is a component of the lethal triad that worsens **coagulopathy** by inhibiting the clotting cascade; metabolic rewarming is required, not cooling.
- While stability is the goal, waiting to be completely off vasopressors might dangerously delay **source control** if the infection is driving the shock.
*Initiate high-dose vasopressors to maintain MAP >75 mmHg and early enteral nutrition*
- Focus should be on **volume resuscitation** and reversing tissue hypoxia (lactate) rather than solely escalating vasopressors, which can cause **mesenteric ischemia**.
- **Early enteral nutrition** is contraindicated in the immediate postoperative phase of an open abdomen with significant **hemodynamic instability** and high pressor requirements.
*Administer massive transfusion protocol and emergency re-exploration within 6 hours*
- **Massive transfusion protocol** is typically reserved for active, uncontrolled hemorrhage, whereas this patient primarily requires reversal of **septic shock** and metabolic derangements.
- **Re-exploration within 6 hours** is too early for a damage control patient who has not yet been adequately rewarmed or had their **acidosis** corrected.
Question 3: A 70-year-old man with recently diagnosed small cell lung cancer presents with septic shock from pneumonia. After initial resuscitation, he requires norepinephrine 0.6 mcg/kg/min and has a lactate of 7.8 mmol/L. His SOFA score is 14. The family requests 'everything be done,' but the patient had previously told his oncologist he would not want prolonged intensive care if his cancer prognosis was poor. Staging shows extensive-stage disease. The ICU team debates goals of care. What represents the most ethically appropriate approach to decision-making?
A. Continue maximum therapy per family wishes as they are legal decision-makers
B. Obtain ethics consultation to overrule family wishes based on futility
C. Arrange urgent palliative care consultation and family meeting to discuss patient's previously expressed wishes and realistic prognosis (Correct Answer)
D. Continue current therapy for 72 hours then reassess based on clinical trajectory
E. Transition to comfort care based on poor oncologic prognosis and high SOFA score
Explanation: ***Arrange urgent palliative care consultation and family meeting to discuss patient's previously expressed wishes and realistic prognosis***
- The most ethically sound approach is to use **substituted judgment**, which prioritizes the patient's **previously expressed wishes** about avoiding prolonged intensive care.
- A **multidisciplinary family meeting** helps reconcile medical reality with patient values, ensuring informed **shared decision-making** rather than a unilateral or discordant approach.
*Continue maximum therapy per family wishes as they are legal decision-makers*
- While families are **surrogate decision-makers**, their role is to advocate for what the **patient would want**, not their own personal desires.
- Blindly following "everything be done" ignores the patient's prior statement to his oncologist and risks providing **non-beneficial treatment**.
*Obtain ethics consultation to overrule family wishes based on futility*
- The term **medical futility** is often controversial; ethics consultations are designed to **mediate conflicts** rather than simply provide a mechanism to overrule families.
- Unilateral decisions should only follow exhaustive attempts at **communication and mediation**, which have not yet occurred in this case.
*Continue current therapy for 72 hours then reassess based on clinical trajectory*
- A "time-limited trial" is a valid tool but fails to address the immediate ethical conflict regarding the **patient's autonomous refusal** of prolonged care.
- This approach may unnecessarily prolong the dying process and ignore the **prognostic alignment** required between the oncology and ICU teams.
*Transition to comfort care based on poor oncologic prognosis and high SOFA score*
- Clinicians should not unilaterally transition to **comfort care** without discussing the patient's prognosis and values with the family/surrogates first.
- While the **high SOFA score** and extensive cancer indicate a poor prognosis, the process must respect the legal and ethical requirements of **informed consent and withdrawal of care**.
Question 4: A 63-year-old man with septic shock from pneumonia has been on mechanical ventilation for 48 hours. He received 6 liters of crystalloid in the first 24 hours and requires norepinephrine 0.25 mcg/kg/min to maintain MAP of 68 mmHg. Physical examination shows bilateral crackles, jugular venous distension, and 2+ pitting edema. Chest X-ray shows bilateral infiltrates and pulmonary edema. PaO2/FiO2 ratio is 180. CVP is 16 mmHg. What is the most appropriate fluid management strategy at this point?
A. Continue maintenance fluids at 100 mL/hr and reassess in 24 hours
B. Increase crystalloid rate to 150 mL/hr to maintain adequate CVP
C. Initiate conservative fluid strategy with diuresis once shock has resolved (Correct Answer)
D. Start continuous renal replacement therapy for fluid removal
E. Administer additional 1-liter fluid bolus to improve oxygen delivery
Explanation: ***Initiate conservative fluid strategy with diuresis once shock has resolved***
- The **FACTT trial** demonstrated that a **conservative fluid strategy** in patients with **ARDS** reduces ventilator days and improves lung function without increasing non-pulmonary organ failure.
- This patient shows clear signs of **fluid overload** (pulmonary edema, elevated CVP, and 2+ edema); thus, negative fluid balance is indicated once hemodynamic stability/vasopressor weaning begins.
*Continue maintenance fluids at 100 mL/hr and reassess in 24 hours*
- Continuing maintenance fluids in the setting of **volume overload** (distended jugular veins, crackles) exacerbates **pulmonary edema** and potentially worsens the **PaO2/FiO2 ratio**.
- A protocolized approach to achieving a neutral or negative fluid balance is preferred over passive observation once the initial resuscitation phase is complete.
*Increase crystalloid rate to 150 mL/hr to maintain adequate CVP*
- Using a **CVP** target of 16 mmHg is physiologically inappropriate, as a high CVP increases **hydrostatic pressure** in the lungs, worsening gas exchange in **ARDS**.
- High fluid infusion rates during the **de-escalation phase** of shock are associated with increased mortality and prolonged mechanical ventilation.
*Start continuous renal replacement therapy for fluid removal*
- **CRRT** is an invasive procedure indicated for refractory volume overload or severe **acute kidney injury (AKI)** associated with uremia or electrolyte imbalances.
- It is not the first-line therapy for fluid management if the patient is hemodynamically stable enough to tolerate **pharmacological diuresis** (e.g., loop diuretics).
*Administer additional 1-liter fluid bolus to improve oxygen delivery*
- Large fluid boluses at this stage would worsen **lung compliance** and oxygenation by increasing **extravascular lung water**.
- The patient already has a high **CVP (16 mmHg)** and signs of congestion, indicating that further fluid will not increase cardiac output but will worsen **interstitial edema**.
Question 5: A 45-year-old woman with acute myeloid leukemia (AML) and neutropenia (absolute neutrophil count 100/mm³) develops septic shock with BP 75/40 mmHg, temperature 39.8°C, and lactate 6.2 mmol/L. Blood cultures are pending. She was recently hospitalized for chemotherapy. Two weeks ago, she had a urinary tract infection treated with ciprofloxacin. She has a central venous catheter in place. Which empiric antibiotic regimen is most appropriate?
A. Vancomycin plus piperacillin-tazobactam
B. Linezolid plus aztreonam
C. Meropenem plus vancomycin plus micafungin (Correct Answer)
D. Vancomycin plus cefepime
E. Ceftriaxone plus metronidazole
Explanation: ***Meropenem plus vancomycin plus micafungin***
- **Meropenem** is required because the patient's recent hospitalization and **ciprofloxacin exposure** increase the risk of **ESBL-producing** organisms and resistant **Pseudomonas aeruginosa**.
- **Vancomycin** addresses the risk of **MRSA** related to the **central venous catheter**, while **micafungin** is indicated for suspected **invasive candidiasis** in a patient with prolonged **neutropenia** and **septic shock**.
*Vancomycin plus piperacillin-tazobactam*
- While it provides broad coverage, **piperacillin-tazobactam** may not be sufficient for **ESBL-producing Enterobacteriaceae** which are more likely due to prior fluoroquinolone use.
- This regimen lacks the **empiric antifungal** coverage (e.g., micafungin) necessary for a neutropenic patient in worsening **hemodynamic instability**.
*Linezolid plus aztreonam*
- **Aztreonam** lacks activity against **Gram-positive** and many **Gram-negative** organisms, making it an inappropriate choice for monotherapy in **septic shock** unless there is a severe penicillin allergy.
- **Linezolid** is generally not preferred over **vancomycin** for initial empiric treatment of **catheter-related bloodstream infections** in acute sepsis.
*Vancomycin plus cefepime*
- **Cefepime** covers **Pseudomonas** but is less effective than **carbapenems** against **ESBL-producing** species common in patients with recent antibiotic exposure.
- This combination lacks coverage for **fungal pathogens**, which must be considered in patients with persistent **neutropenic fever** and **multiorgan failure**.
*Ceftriaxone plus metronidazole*
- **Ceftriaxone** is inappropriate because it lacks **anti-pseudomonal** activity, which is a mandatory requirement for **febrile neutropenia** management.
- **Metronidazole** provides anaerobic coverage but does not address the primary risks of **MRSA**, resistant **Gram-negative bacilli**, or **Candida** species in this patient.
Question 6: A 58-year-old man with cirrhosis develops septic shock from spontaneous bacterial peritonitis. After 4 liters of crystalloid and initiation of norepinephrine, his BP is 88/52 mmHg (MAP 64 mmHg) on norepinephrine 0.5 mcg/kg/min. Random cortisol level is 18 mcg/dL. Lactate is 5.2 mmol/L. The ICU team debates adding hydrocortisone. Based on current evidence, what is the most appropriate approach regarding corticosteroid therapy?
A. Administer hydrocortisone 200 mg/day given refractory shock requiring high-dose norepinephrine (Correct Answer)
B. Start hydrocortisone only if norepinephrine dose exceeds 1.0 mcg/kg/min
C. Withhold corticosteroids as random cortisol >15 mcg/dL excludes adrenal insufficiency
D. Administer stress-dose corticosteroids only if cosyntropin stimulation test shows inadequate response
E. Perform cosyntropin stimulation test before deciding on corticosteroid therapy
Explanation: ***Administer hydrocortisone 200 mg/day given refractory shock requiring high-dose norepinephrine***
- According to **Surviving Sepsis Campaign** guidelines, intravenous **hydrocortisone** at a dose of 200 mg/day is recommended for patients with **septic shock** who require ongoing vasopressor therapy (e.g., norepinephrine ≥0.25 mcg/kg/min for at least 4 hours).
- It has been shown to speed the **resolution of shock** and improve hemodynamics in patients with **refractory hypotension** despite adequate fluid resuscitation.
*Start hydrocortisone only if norepinephrine dose exceeds 1.0 mcg/kg/min*
- Waiting for a dose of **1.0 mcg/kg/min** is unnecessarily high; the threshold for "refractory shock" where steroids are beneficial is typically reached much earlier (around **0.25–0.5 mcg/kg/min**).
- Delaying therapy in the setting of rising **lactate** and failing mean arterial pressure (MAP) may result in worse outcomes.
*Withhold corticosteroids as random cortisol >15 mcg/dL excludes adrenal insufficiency*
- Random **cortisol levels** are notoriously unreliable in the critical care setting due to changes in **cortisol-binding globulin** and the pulsar nature of secretion.
- Clinical guidelines specifically recommend against using **random serum cortisol** levels to guide the decision to start corticosteroids in septic shock.
*Administer stress-dose corticosteroids only if cosyntropin stimulation test shows inadequate response*
- The **CORTICUS trial** demonstrated that the response to a **cosyntropin stimulation test** does not accurately predict which patients will benefit from corticosteroid therapy in sepsis.
- Current guidelines favor clinical criteria (vasopressor persistence) over **ACTH stimulation tests** to initiate treatment.
*Perform cosyntropin stimulation test before deciding on corticosteroid therapy*
- Performing a **cosyntropin stimulation test** causes unnecessary delay in the management of **septic shock** and does not provide actionable prognostic data for steroid initiation.
- The diagnosis of **Critical Illness-Related Corticosteroid Insufficiency (CIRCI)** is now primarily a clinical diagnosis in the context of vasopressor-dependent shock.
Question 7: A 72-year-old woman with COPD and atrial fibrillation on warfarin presents with septic shock secondary to urosepsis. After initial resuscitation, she requires norepinephrine 0.4 mcg/kg/min to maintain MAP of 65 mmHg. INR is 3.2. She develops bright red blood per rectum with hemoglobin drop from 11 g/dL to 8.5 g/dL over 4 hours. Hemodynamics remain stable with current vasopressor support. What is the most appropriate transfusion strategy?
A. Transfuse to hemoglobin >10 g/dL given active bleeding and vasopressor requirement
B. Withhold transfusion and observe given stable hemodynamics
C. Administer fresh frozen plasma and vitamin K before considering red blood cell transfusion
D. Transfuse immediately to hemoglobin >9 g/dL given history of atrial fibrillation
E. Transfuse to hemoglobin >7 g/dL unless hemodynamic instability develops (Correct Answer)
Explanation: ***Transfuse to hemoglobin >7 g/dL unless hemodynamic instability develops***
- A **restrictive transfusion strategy** (threshold of 7 g/dL) is standard for most critically ill patients, including those with **sepsis**, as evidenced by the TRICC and TRISS trials.
- Even in the presence of **active gastrointestinal bleeding**, a restrictive strategy (threshold 7 g/dL) has been shown to improve outcomes and decrease **rebleeding risk** compared to liberal strategies.
*Transfuse to hemoglobin >10 g/dL given active bleeding and vasopressor requirement*
- A **liberal transfusion threshold** of 10 g/dL is unnecessary and can lead to complications such as **volume overload** and increased inflammatory response.
- Higher thresholds are generally reserved only for those with **acute myocardial ischemia** or life-threatening hemorrhage with hemodynamic collapse.
*Withhold transfusion and observe given stable hemodynamics*
- While the patient is currently stable, a hemoglobin of 8.5 g/dL allows for observation, but the strategy must include a **defined trigger** (7 g/dL) for transfusion during active bleeding.
- Complete withholding is inappropriate if the hemoglobin continues to drop below the **critical threshold** of 7 g/dL in a patient with septic shock.
*Administer fresh frozen plasma and vitamin K before considering red blood cell transfusion*
- Although reversing the **elevated INR** (3.2) is necessary to control bleeding, it does not replace the need for **Packed RBCs** if the hemoglobin falls below the safe threshold.
- **Prothrombin Complex Concentrate (PCC)** is generally preferred over FFP for rapid warfarin reversal in the setting of major bleeding to avoid **volume overload**.
*Transfuse immediately to hemoglobin >9 g/dL given history of atrial fibrillation*
- A history of **atrial fibrillation** is not an indication for a higher transfusion threshold; this is typically reserved for **active ACS** or acute brain injury.
- Restrictive strategies remain superior in most cardiac patients unless they are experiencing **symptomatic anemia** or acute coronary events.
Question 8: A 42-year-old man with acute pancreatitis develops fever, tachycardia, and hypotension. Initial resuscitation with crystalloids and norepinephrine is started. Six hours later, despite MAP of 68 mmHg on norepinephrine at 0.3 mcg/kg/min, his lactate remains elevated at 4.8 mmol/L and urine output is 15 mL/hr. Central venous oxygen saturation (ScvO2) is 62%. What intervention should be implemented?
A. Add vasopressin as a second vasopressor agent
B. Increase norepinephrine dose to achieve MAP >75 mmHg
C. Start broad-spectrum antifungal therapy
D. Administer additional fluid bolus and reassess perfusion parameters (Correct Answer)
E. Initiate renal replacement therapy for oliguria
Explanation: ***Administer additional fluid bolus and reassess perfusion parameters***
- The patient shows signs of **persistent tissue hypoperfusion** (elevated lactate, oliguria, and **low ScvO2 <70%**) despite achieving a target **MAP >65 mmHg**, suggesting inadequate effective circulating volume.
- Initial management of **septic-like shock** in acute pancreatitis requires optimizing **preload** to improve oxygen delivery before escalating to higher-dose vasopressors or invasive interventions.
*Add vasopressin as a second vasopressor agent*
- Vasopressin is typically added when **high-dose norepinephrine** is required to maintain MAP, but it does not address underlying **volume depletion** indicated by low ScvO2.
- Adding a second vasopressor without ensuring **fluid resuscitation** may worsen peripheral ischemia and organ perfusion in a fluid-responsive patient.
*Increase norepinephrine dose to achieve MAP >75 mmHg*
- Target **MAP of 65 mmHg** is generally sufficient for most patients; increasing the target does not necessarily improve cellular **oxygen delivery** or resolve **lactic acidosis**.
- Excessive **vasoconstriction** from higher doses of norepinephrine can further reduce **microcirculatory flow** and worsen renal perfusion.
*Start broad-spectrum antifungal therapy*
- Antifungal therapy is not indicated as an initial step in the management of early **septic shock** unless there are specific risk factors like long-term TPN or known **candidemia**.
- Fever and hypotension in early **acute pancreatitis** are more commonly due to **SIRS** or bacterial translocation rather than fungal infections.
*Initiate renal replacement therapy for oliguria*
- Oliguria in this context is likely **prerenal**, secondary to **hypovolemia** and inadequate renal perfusion, and should first be treated with volume expansion.
- **Dialysis** is indicated for refractory fluid overload, severe electrolyte imbalances, or metabolic acidosis, but not as the first-line treatment for **reversible oliguria**.
Question 9: A 55-year-old woman with metastatic breast cancer develops septic shock from pneumonia. After initial fluid resuscitation of 30 mL/kg, her blood pressure remains 80/45 mmHg with a mean arterial pressure (MAP) of 57 mmHg. Heart rate is 120/min, central venous pressure is 12 mmHg, and lactate is 4.2 mmol/L. She has received broad-spectrum antibiotics. What is the next best step in management?
A. Administer hydrocortisone 200 mg IV daily
B. Administer an additional 30 mL/kg crystalloid bolus
C. Initiate norepinephrine infusion targeting MAP ≥65 mmHg (Correct Answer)
D. Perform bedside echocardiography before any intervention
E. Start dobutamine for inotropic support
Explanation: ***Initiate norepinephrine infusion targeting MAP ≥65 mmHg***
- Per the **Surviving Sepsis Campaign** guidelines, **norepinephrine** is the first-line vasopressor for patients who remain hypotensive (MAP <65 mmHg) despite adequate **fluid resuscitation (30 mL/kg)**.
- This patient satisfies the definition of **septic shock** with persistent hypotension and **hyperlactatemia** (lactate >2 mmol/L), requiring vasopressors to maintain organ perfusion.
*Administer hydrocortisone 200 mg IV daily*
- **Corticosteroids** are only indicated in septic shock if hemodynamic stability is not achieved after adequate fluid resuscitation and **vasopressor therapy**.
- Using them as a first-line intervention before starting vasopressors is not consistent with current **standard of care** protocols.
*Administer an additional 30 mL/kg crystalloid bolus*
- The patient has already received the recommended initial fluid challenge, and her **Central Venous Pressure (CVP)** of 12 mmHg suggests adequate preload.
- Excessive **fluid administration** can lead to pulmonary edema and adverse outcomes; therefore, **vasopressors** should be prioritized when initial resuscitation fails.
*Perform bedside echocardiography before any intervention*
- While **echocardiography** is useful for assessing cardiac function in shock, it should not delay the initiation of **life-saving vasopressors** in a hypotensive patient.
- The immediate priority is restoring the **Mean Arterial Pressure (MAP)** to prevent further tissue hypoxia and multi-organ failure.
*Start dobutamine for inotropic support*
- **Dobutamine** is indicated primarily in cases of persistent hypoperfusion despite adequate MAP and fluid status, usually due to **myocardial dysfunction**.
- Since the primary issue here is **vasomotor tone** and low MAP, the vasoconstrictive effects of **norepinephrine** are required first.
Question 10: A 68-year-old man with diabetes presents to the emergency department with fever, hypotension (BP 85/50 mmHg), and altered mental status. Temperature is 39.2°C (102.5°F), heart rate is 115/min, and respiratory rate is 28/min. Laboratory studies show WBC 18,000/mm³ with 15% bands, lactate 3.5 mmol/L, and creatinine 2.1 mg/dL (baseline 1.0 mg/dL). Blood cultures are drawn. What is the most appropriate initial management?
A. Start norepinephrine immediately before fluid resuscitation
B. Administer corticosteroids and then broad-spectrum antibiotics
C. Administer broad-spectrum antibiotics within 1 hour and begin fluid resuscitation with 30 mL/kg crystalloid (Correct Answer)
D. Obtain CT scan of abdomen and pelvis before initiating antibiotics
E. Begin fluid resuscitation and wait for culture results before starting antibiotics
Explanation: ***Administer broad-spectrum antibiotics within 1 hour and begin fluid resuscitation with 30 mL/kg crystalloid***
- This patient presents with **septic shock**, defined by suspected infection, **hypotension** (BP 85/50), and **hyperlactatemia** (3.5 mmol/L).
- The priority is to implement the **1-hour bundle**, which includes rapid **intravenous crystalloid** resuscitation and **early empiric antibiotics** to reduce mortality.
*Start norepinephrine immediately before fluid resuscitation*
- **Norepinephrine** is the first-line vasopressor for septic shock, but it should typically follow or be concurrent with **initial fluid resuscitation** (30 mL/kg).
- Using vasopressors without adequate **intravascular volume** can lead to further tissue ischemia due to vasoconstriction.
*Administer corticosteroids and then broad-spectrum antibiotics*
- **Hydrocortisone** is only indicated in patients with septic shock who remain **hemodynamically unstable** despite adequate fluid and vasopressor therapy.
- Antibiotics must never be delayed for the administration of adjunctive treatments like **corticosteroids**.
*Obtain CT scan of abdomen and pelvis before initiating antibiotics*
- While **source control** is vital for sepsis management, imaging should never delay the administration of **broad-spectrum antibiotics** in the setting of shock.
- Diagnostic procedures must be prioritized only after **stabilization** of blood pressure and initiation of empiric therapy.
*Begin fluid resuscitation and wait for culture results before starting antibiotics*
- Mortality in sepsis increases for every hour that **antibiotic administration** is delayed; waiting for **culture growth** (which takes 24-48 hours) is life-threatening.
- Blood cultures must be **drawn** before antibiotics are started, but the medication should be given immediately after the draw is completed.
