,Q1. A patient with decompensated heart failure and acute kidney injury is receiving intravenous
furosemide and dopamine. Which finding indicates that the dopamine infusion is achieving the
desired effect on renal perfusion?
A. Heart rate increases from 72 to 88 beats per minute
B. Mean arterial pressure remains stable at 65 mm Hg
C. Urine output increases from 10 mL/hr to 40 mL/hr over 2 hours
D. Serum potassium decreases from 5.2 to 4.8 mEq/L
Correct Answer: C. Urine output increases from 10 mL/hr to 40 mL/hr over 2 hours
Rationale: At low doses (1-5 mcg/kg/min), dopamine stimulates dopaminergic receptors in the renal
vasculature, causing vasodilation and increased renal blood flow, which enhances urine output. Increased
urine output is the direct indicator of improved renal perfusion. Increased heart rate (A) indicates beta-1
stimulation at higher doses. Stable MAP (B) is not specific to renal effect. Decreased potassium (D) is
more likely from furosemide.
Why Wrong:
A - Tachycardia indicates beta-1 adrenergic activation, not renal-specific effect.
B - Stable MAP reflects systemic perfusion, not renal perfusion specifically.
D - Hypokalemia is primarily due to loop diuretic effect, not dopamine.

Q2. A patient with cirrhosis and ascites develops hepatic encephalopathy. After lactulose therapy,
the patient's mental status improves. Which laboratory value best confirms the therapeutic response
to lactulose?
A. Serum albumin of 3.0 g/dL
B. Stool pH of 5.0
C. Serum ammonia level of 40 mcg/dL
D. Prothrombin time of 14 seconds
Correct Answer: B. Stool pH of 5.0
Rationale: Lactulose works by acidifying the colon, which traps ammonia as ammonium (NH4+) in the
stool, enhancing its elimination. A stool pH of 5.0 indicates adequate acidification, which correlates with
clinical improvement. While serum ammonia may decrease (C), it is not always reliable and can be
normal in some patients with encephalopathy. Albumin (A) and PT (D) reflect synthetic function, not
lactulose effect.
Why Wrong:
A - Albumin is a marker of liver synthetic function, not lactulose efficacy.
C - Serum ammonia levels correlate poorly with encephalopathy severity and are not the best
indicator of lactulose response.
D - Prothrombin time reflects coagulation factor synthesis, unrelated to lactulose.

, Q3. A patient with septic shock is being managed with norepinephrine and broad-spectrum
antibiotics. The nurse notes that the patient's mean arterial pressure (MAP) remains 58 mm Hg
despite titration of norepinephrine. Which intervention should the nurse anticipate next?
A. Add vasopressin as a second vasopressor
B. Increase norepinephrine infusion rate to maximum dose
C. Administer a fluid bolus of 500 mL normal saline
D. Start intravenous hydrocortisone 50 mg every 6 hours
Correct Answer: A. Add vasopressin as a second vasopressor
Rationale: In septic shock, if MAP remains <65 mm Hg despite norepinephrine (first-line vasopressor),
the Surviving Sepsis Campaign guidelines recommend adding vasopressin (0.03 units/min) as a second
agent to achieve target MAP. Vasopressin is synergistic with norepinephrine and may allow lower
catecholamine doses. Increasing norepinephrine to maximum (B) risks adverse effects; fluid bolus (C)
would be considered if hypovolemia is suspected, but the patient is already on vasopressors;
hydrocortisone (D) is reserved for refractory shock if vasopressors fail despite adequate volume.
Why Wrong:
B - Maximizing norepinephrine increases risk of arrhythmias and ischemia without proven benefit
over adding a second agent.
C - Fluid resuscitation should be optimized before vasopressors, but if MAP remains low after
adequate fluid, additional fluid may not help.
D - Corticosteroids are recommended only if vasopressor dependence persists after achieving MAP
with vasopressors.
Reference: Surviving Sepsis Campaign (2021). Intensive Care Medicine, 47(11):1181-1247.
Q4. A patient with acute respiratory distress syndrome (ARDS) is on volume-controlled mechanical
ventilation with a tidal volume of 6 mL/kg ideal body weight, PEEP of 12 cm H2O, and FiO2 of 0.7.
Arterial blood gas shows pH 7.25, PaCO2 55 mm Hg, PaO2 65 mm Hg, HCO3- 24 mEq/L. Which
adjustment should the nurse anticipate?
A. Increase tidal volume to 8 mL/kg
B. Increase respiratory rate to 24 breaths/min
C. Decrease PEEP to 8 cm H2O
D. Increase FiO2 to 0.9
Correct Answer: B. Increase respiratory rate to 24 breaths/min
Rationale: The ABG shows acute respiratory acidosis (pH <7.35, PaCO2 >45, HCO3- normal). In ARDS,
low tidal volume ventilation (6 mL/kg) is standard to prevent volutrauma, so increasing tidal volume (A)
is not recommended. The appropriate intervention is to increase the respiratory rate to enhance minute
ventilation and lower PaCO2. PEEP (C) is already at 12 cm H2O; decreasing it could worsen
oxygenation. FiO2 (D) is acceptable at 0.7 with PaO2 65 mm Hg (goal >55-60), and increasing FiO2
does not address hypercapnia.
Why Wrong:
A - Increasing tidal volume above 6 mL/kg increases risk of ventilator-induced lung injury; not
recommended in ARDS.
C - Decreasing PEEP may cause derecruitment and worsen oxygenation; PEEP is already moderate
and should be adjusted based on oxygenation, not pH.
D - FiO2 increase would not correct respiratory acidosis and may increase oxygen toxicity risk.
