,Q1. A patient with septic shock has received 30 mL/kg of crystalloid. Repeat assessment shows
central venous pressure 8 mm Hg, mean arterial pressure 62 mm Hg, and lactate 3.5 mmol/L.
Which intervention is most appropriate?
A. Continue IV fluid bolus at 20 mL/kg
B. Start norepinephrine infusion
C. Administer dobutamine
D. Obtain a focused cardiac ultrasound
Correct Answer: B. Start norepinephrine infusion
Rationale: The patient remains hypotensive despite adequate fluid resuscitation (CVP 8 mm Hg suggests
euvolemia). Per surviving sepsis guidelines, vasopressors (norepinephrine) are indicated after initial fluid
bolus when MAP remains below 65 mm Hg. Continuing fluids risks overload, dobutamine is for low
cardiac output, and ultrasound may be helpful but would delay necessary vasopressor initiation.
Why Wrong:
A - CVP is adequate; further fluid bolus increases risk of pulmonary edema without improving
perfusion.
C - Dobutamine is indicated for low cardiac output, not primarily for hypotension without signs of
myocardial dysfunction.
D - Focused cardiac ultrasound is a temporizing measure; vasopressor should be initiated
simultaneously if not already started.

Sepsis Campaign Guidelines 2021.
Q2. A patient with a history of COPD and chronic hypercapnia presents with acute dyspnea.
Arterial blood gas: pH 7.30, PaCO 60 mm Hg, HCO 30 mEq/L, PaO 55 mm Hg on room air. What
is the interpretation?
A. Acute respiratory acidosis with metabolic compensation
B. Chronic respiratory acidosis with acute exacerbation
C. Mixed metabolic alkalosis and respiratory acidosis
D. Acute respiratory acidosis with no compensation
Correct Answer: B. Chronic respiratory acidosis with acute exacerbation
Rationale: The elevated HCO ƒ { (30 mEq/L) indicates chronic compensation for baseline hypercapnia.
The pH is acidic (7.30) and PaCO is high (60 mm Hg), reflecting an acute on chronic process. In chronic
respiratory acidosis, the expected HCO increases by 3-5 mEq/L per 10 mm Hg increase in PaCO. This
patient's HCO matches chronic compensation with an additional acute rise in PaCO.
Why Wrong:
A - Metabolic compensation would not be present in an acute-only acidosis; the elevated HCO
suggests chronicity.
C - Metabolic alkalosis would show pH >7.45 and HCO >30; here pH is low and PaCO high,
consistent with acidosis.
D - The HCO elevation indicates compensation, so it is not uncompensated.

,Q3. A patient with 40% total body surface area burns arrives 2 hours after injury weighing 80 kg.
Using the Parkland formula, what is the total crystalloid volume to be infused in the first 24 hours?
A. 6,400 mL
B. 12,800 mL
C. 10,000 mL
D. 7,200 mL
Correct Answer: B. 12,800 mL
Rationale: The Parkland formula: 4 mL × weight (kg) × %TBSA. Here, 4 × 80 × 40 = 12,800 mL. Half is
given in the first 8 hours from the time of injury, and the remaining half over the next 16 hours. Since
arrival is at 2 hours, the first half (6,400 mL) must be infused over 6 hours (8 - 2 = 6).
Why Wrong:
A - 6,400 mL is only half of the calculated 24-hour volume.
C - 10,000 mL does not correspond to any standard calculation (4 × 80 × 40 = 12,800).
D - 7,200 mL would result from an incorrect formula, e.g., 2 mL/kg/%TBSA.

Q4. A patient with an inferior ST-elevation myocardial infarction develops hypotension, muffled
heart sounds, and jugular venous distention. The nurse suspects cardiac tamponade. Which
intervention is priority?
A. Administer IV fluid bolus 500 mL
B. Prepare for pericardiocentesis
C. Administer morphine for pain
D. Activate the cardiac catheterization lab
Correct Answer: B. Prepare for pericardiocentesis
Rationale: Cardiac tamponade requires immediate decompression via pericardiocentesis. While fluids
may temporarily support preload, definitive treatment is drainage of pericardial fluid. The triad of
hypotension, muffled heart sounds, and JVD (Beck's triad) is classic for tamponade. Morphine can
worsen hypotension; activation of cath lab is appropriate for STEMI but not tamponade.
Why Wrong:
A - IV fluids are a temporizing measure but do not relieve tamponade; pericardiocentesis is
definitive.
C - Morphine may reduce preload and exacerbate hypotension in tamponade.
D - Cardiac catheterization would be for revascularization of STEMI, but tamponade requires
immediate pericardiocentesis.

Disorders).

, Q5. A patient with acute ischemic stroke has an INR of 2.8. Which factor most contraindicates
administration of alteplase?
A. Onset of symptoms 3 hours ago
B. Blood pressure 185/110 mm Hg
C. INR 2.8
D. Platelet count 120,000/mm³
Correct Answer: C. INR 2.8
Rationale: Alteplase is contraindicated if INR >1.7 in patients on warfarin. An INR of 2.8 indicates high
bleeding risk. Onset within 3 hours is within the window, BP >185/110 is a contraindication if not
controlled, but options only list the BP value without stating if it is sustained. Platelet count >100,000 is
acceptable. However, INR is an absolute contraindication.
Why Wrong:
A - Onset within 3 hours is within the standard 4.5-hour window for alteplase, so not
contraindicated.
B - BP >185/110 is a contraindication only if it does not respond to treatment; the question does not
indicate failed control, so it is less absolute than INR.
D - Platelet count 120,000/mm³ is above the minimum of 100,000, so not a contraindication.

Acute Ischemic Stroke.
Q6. A patient with sepsis develops petechiae, prolonged PT/PTT, elevated D-dimer, and fibrinogen
80 mg/dL. Which condition is most likely?
A. Thrombotic thrombocytopenic purpura
B. Heparin-induced thrombocytopenia
C. Disseminated intravascular coagulation
D. Immune thrombocytopenia
Correct Answer: C. Disseminated intravascular coagulation
Rationale: The combination of microvascular bleeding (petechiae), prolonged coagulation times, elevated
D-dimer (fibrin degradation), and low fibrinogen is classic for disseminated intravascular coagulation
(DIC). DIC often complicates sepsis. TTP shows microangiopathic hemolytic anemia and low platelets
but normal PT/PTT; HIT is related to heparin; ITP has low platelets only.
Why Wrong:
A - TTP features thrombocytopenia, microangiopathic hemolytic anemia, fever, neurological
changes, and renal dysfunction, not prolonged PT/PTT.
B - HIT occurs after heparin exposure and presents with thrombocytopenia and thrombosis, not
prolonged PT/PTT and low fibrinogen.
D - ITP is isolated thrombocytopenia without coagulation factor depletion.
