SECTION 1: MULTISYSTEM ORGAN DYSFUNCTION SYNDROME (MODS) Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 68-year-old man is postoperative day 3 after an open abdominal aortic aneurysm
repair. Over the past 12 hours, his temperature has risen to 38.9°C, heart rate is 118,
respiratory rate is 26, and WBC is 16,500. He now has new-onset confusion, urine output
has dropped to 15 mL/hr, and his PaO2/FiO2 ratio is 220. The nurse recognizes these
findings as consistent with the progression of what pathophysiologic process?
A. Localized wound infection with compensatory hypermetabolism
B. Systemic inflammatory response leading to multisystem organ dysfunction ✓
CORRECT
C. Anaphylactic reaction to perioperative antibiotic prophylaxis
D. Acute hypovolemia from postoperative third-spacing
Correct Answer: B
Rationale: SIRS progressing to MODS is characterized by systemic inflammation
causing microvascular injury and tissue hypoperfusion, which explains the new organ
,failures in this postoperative patient. Localized wound infection would not account for
the multisystem involvement including renal and respiratory dysfunction. Early
recognition of this progression allows timely intervention before irreversible organ
damage occurs.
Question 2 of 50
A 54-year-old woman with severe acute pancreatitis develops increasing oxygen
requirements, a creatinine that has doubled from baseline, and petechiae on her trunk
and extremities. Her lactate has risen from 1.8 to 4.6 mmol/L over 8 hours. Which
finding most directly indicates the severity of her evolving organ dysfunction?
A. Serum lipase of 2,400 units/L
B. Total bilirubin of 2.1 mg/dL
C. Arterial lactate of 4.6 mmol/L ✓ CORRECT
D. Serum calcium of 8.2 mg/dL
Correct Answer: C
Rationale: Elevated arterial lactate directly reflects tissue hypoperfusion and anaerobic
metabolism, making it a key indicator of MODS severity and shock progression. While
elevated lipase confirms pancreatitis, it does not measure organ dysfunction severity or
perfusion status. Lactate clearance is commonly used to guide resuscitation
effectiveness in critical care.
Question 3 of 50
A 45-year-old man with MODS secondary to septic shock has developed abdominal
distension, feeding intolerance, and new-onset bacteremia with Enterococcus species.
The critical care nurse recognizes that these findings most likely indicate which
complication of MODS?
A. Loss of gut mucosal integrity with bacterial translocation ✓ CORRECT
, B. Acute mesenteric ischemia from low-flow states
C. Clostridioides difficile colitis from broad-spectrum antibiotics
D. Stress ulceration requiring proton pump inhibitor therapy
Correct Answer: A
Rationale: Gut mucosal barrier dysfunction allows translocation of enteric bacteria and
endotoxins into the bloodstream, explaining the enterococcal bacteremia and feeding
intolerance in this septic patient. Acute mesenteric ischemia typically presents with
severe abdominal pain and bloody stools rather than isolated feeding intolerance.
Maintaining gut integrity through early enteral nutrition is a core strategy in MODS
management.
Question 4 of 50
A 72-year-old woman with MODS is receiving mechanical ventilation, vasopressors, and
continuous renal replacement therapy. Her morning labs reveal a platelet count of
48,000, fibrinogen of 110 mg/dL, and D-dimer greater than 8,000 ng/mL. She is oozing
from her endotracheal tube and IV insertion sites. Which intervention should the nurse
anticipate as the priority?
A. Administer fresh frozen plasma to correct INR
B. Initiate therapeutic heparin for suspected pulmonary embolism
C. Transfuse packed red blood cells for occult bleeding
D. Prepare for cryoprecipitate and platelet transfusion ✓ CORRECT
Correct Answer: D
Rationale: The combination of thrombocytopenia, low fibrinogen, elevated D-dimer, and
active bleeding indicates disseminated intravascular coagulation, requiring
cryoprecipitate to replace fibrinogen and platelets to address severe thrombocytopenia.
Fresh frozen plasma would correct clotting factor deficiencies but does not address the
critically low fibrinogen or platelet count. DIC in MODS requires replacement of
consumed clotting components while treating the underlying trigger.
