,Q1. A patient with septic shock is receiving norepinephrine at 12 mcg/min via central line. The mean arterial
pressure (MAP) remains at 58 mm Hg despite fluid resuscitation. The provider orders vasopressin 0.04
units/min. Which mechanism best explains the synergistic effect of adding vasopressin to norepinephrine?
A. Vasopressin activates V2 receptors in the renal collecting ducts, increasing water reabsorption and blood
volume.
B. Vasopressin directly stimulates alpha-1 adrenergic receptors, augmenting peripheral vasoconstriction.
C. Vasopressin sensitizes vascular smooth muscle to catecholamines via V1a receptor activation, restoring
vascular tone.
D. Vasopressin inhibits nitric oxide synthase, reducing vasodilation from sepsis-induced inflammatory
mediators.
Correct Answer: C. Vasopressin sensitizes vascular smooth muscle to catecholamines via V1a receptor
activation, restoring vascular tone.
Rationale: In septic shock, downregulation and desensitization of adrenergic receptors reduce responsiveness to
catecholamines. Vasopressin at low doses (0.01-0.04 units/min) activates V1a receptors on vascular smooth muscle,
which enhances calcium signaling and restores sensitivity to norepinephrine, improving MAP. V2 receptors (A) are
antidiuretic but do not directly increase blood pressure rapidly. Vasopressin is not a direct alpha-agonist (B).
While vasopressin may modulate NO pathways (D), the primary synergistic mechanism is receptor sensitization.
Why Wrong:
A - V2 receptor activation increases water reabsorption, but this effect takes hours to impact blood volume
and does not explain the rapid synergistic pressor effect.
B - Vasopressin does not directly stimulate alpha-1 receptors; its pressor effect is mediated by V1a receptors.
D - Inhibition of nitric oxide synthase is not a primary mechanism of vasopressin; its main effect is
V1a-mediated vasoconstriction and sensitization to catecholamines.

Q2. A patient with acute respiratory distress syndrome (ARDS) is on volume-controlled ventilation with a
tidal volume of 6 mL/kg ideal body weight, PEEP 10 cm H2O, FiO2 0.6. Plateau pressure is 28 cm H2O.
Arterial blood gas shows pH 7.30, PaCO2 55 mm Hg, PaO2 70 mm Hg. Which change in ventilator settings is
most appropriate to improve oxygenation while minimizing ventilator-induced lung injury?
A. Increase tidal volume to 8 mL/kg to improve minute ventilation and reduce PaCO2.
B. Increase PEEP to 15 cm H2O while monitoring for hemodynamic compromise.
C. Increase FiO2 to 0.8 to raise PaO2 without changing PEEP or tidal volume.
D. Switch to pressure-controlled ventilation with a pressure limit of 35 cm H2O.
Correct Answer: B. Increase PEEP to 15 cm H2O while monitoring for hemodynamic compromise.
Rationale: In ARDS with moderate hypoxemia (PaO2/FiO2 ratio ~117), increasing PEEP recruits collapsed
alveoli, improves V/Q matching, and increases PaO2 without excessively raising plateau pressure (currently safe at
28). Higher PEEP may reduce driving pressure and lung strain. Increasing tidal volume (A) risks volutrauma and
barotrauma as plateau pressure would exceed 30 cm H2O. Increasing FiO2 (C) may be less effective and risks
absorption atelectasis. Pressure-controlled ventilation (D) does not guarantee lower driving pressure and may not
improve oxygenation.
Why Wrong:
A - Increasing tidal volume to 8 mL/kg in ARDS with plateau pressure 28 cm H2O would likely push plateau
above 30, increasing risk of VILI.
C - Higher FiO2 may not significantly improve PaO2 if shunt fraction is high; also risk of oxygen toxicity and
absorption atelectasis.
D - Switching to pressure control does not inherently reduce lung injury; the pressure limit of 35 cm H2O
may still cause high tidal volumes.

, Q3. A patient with a history of heart failure with reduced ejection fraction (HFrEF) is admitted for
decompensation. Current medications include lisinopril 20 mg daily, metoprolol succinate 50 mg daily, and
furosemide 40 mg BID. On admission, blood pressure is 98/62 mm Hg, heart rate 62 bpm, serum creatinine
1.8 mg/dL (baseline 1.0), potassium 5.2 mEq/L. Which medication adjustment is most appropriate?
A. Discontinue lisinopril due to hyperkalemia and acute kidney injury.
B. Reduce furosemide to 20 mg BID and continue lisinopril and metoprolol.
C. Hold metoprolol because of bradycardia and hypotension.
D. Continue all medications at current doses and add spironolactone 25 mg daily.
Correct Answer: B. Reduce furosemide to 20 mg BID and continue lisinopril and metoprolol.
Rationale: In acute decompensated HFrEF with fluid overload, reducing diuretic dose may worsen congestion. However, the
patient has mild AKI (likely prerenal) and hyperkalemia. Decreasing furosemide could reduce prerenal azotemia and allow for
better potassium excretion. Lisinopril and metoprolol should be continued if tolerated because they improve long-term
outcomes; the current BP and HR are acceptable. Discontinuing lisinopril (A) would deprive the patient of mortality benefit.
Holding metoprolol (C) is not indicated for mild bradycardia. Adding spironolactone (D) would worsen hyperkalemia.
Why Wrong:
A - Lisinopril has mortality benefit in HFrEF; hyperkalemia is mild and can be managed with dietary restriction and
diuretic adjustment; discontinuation is premature.
C - Metoprolol is a cornerstone therapy; heart rate 62 is acceptable and hypotension is likely due to hypovolemia, not
beta-blocker toxicity.
D - Spironolactone would increase potassium further, risking dangerous hyperkalemia given current K+ 5.2 and AKI.

Q4. A patient in the intensive care unit develops a new fever and hypotension. The nurse reviews the
following data: White blood cell count 18,000/mm³ with 15% bands, lactate 4.2 mmol/L, and procalcitonin
12 ng/mL. Blood cultures are pending. Which intervention should the nurse initiate first?
A. Administer broad-spectrum antibiotics within 1 hour of recognition.
B. Obtain a chest X-ray to identify source of infection.
C. Start a norepinephrine infusion to maintain MAP 65 mm Hg.
D. Draw blood cultures from two sites before administering antibiotics.
Correct Answer: D. Draw blood cultures from two sites before administering antibiotics.
Rationale: According to the Surviving Sepsis Campaign guidelines, blood cultures should be obtained before
antibiotics if it does not delay antibiotic administration by more than 45 minutes. In this scenario, the patient is
hypotensive but not yet in refractory shock; cultures can be drawn quickly. After cultures, antibiotics should be
given within 1 hour. Chest X-ray (B) is important but not the first priority. Norepinephrine (C) may be needed if
fluid resuscitation fails, but initial intervention should be cultures and antibiotics. However, the question asks for
the first intervention; obtaining cultures before antibiotics is crucial for de-escalation.
Why Wrong:
A - Antibiotics should be given as soon as possible, but cultures should be obtained first if it does not cause
significant delay; the question implies cultures can be drawn rapidly.
B - Chest X-ray is useful but not the immediate priority; cultures and antibiotics take precedence.
C - Norepinephrine may be indicated after fluid resuscitation, but the first step is to obtain cultures and start
antibiotics.

Q5. A patient with a subarachnoid hemorrhage from a ruptured aneurysm develops delayed cerebral
ischemia. The nurse notes that the patient's mean arterial pressure is 70 mm Hg and intracranial pressure is
22 mm Hg. Which of the following is the most appropriate nursing intervention?
A. Administer mannitol 0.5 g/kg IV to reduce intracranial pressure.
