,Section A - Management OF CARE
Q1.
A patient with acute decompensated heart failure presents with severe dyspnea, hypoxia,
and hypotension. Despite noninvasive ventilation and diuretics, the condition worsens.
Which intervention is most likely to improve hemodynamics without increasing
myocardial oxygen demand?
A. Initiation of a dobutamine infusion B. Titration of intravenous nitroglycerin
C. Administration of nesiritide D. Placement of an intra-aortic balloon
pump
Correct: D - Placement of an intra-aortic balloon pump
Rationale:The intra-aortic balloon pump (IABP) improves coronary perfusion and reduces
afterload, thereby decreasing myocardial oxygen demand. Dobutamine increases contractility
but also increases oxygen demand. Nitroglycerin and nesiritide are vasodilators that may
worsen hypotension. IABP is the best option in cardiogenic shock refractory to medical
therapy.
Q2.
In a patient with sepsis-induced acute respiratory distress syndrome (ARDS), which
ventilator strategy best balances oxygenation and prevention of ventilator-induced lung
injury?
A. Tidal volume 12 mL/kg ideal body weight B. Tidal volume 6 mL/kg ideal body weight
with plateau pressure < 30 cm H2O with plateau pressure < 30 cm H2O and
permissive hypercapnia
C. Tidal volume 10 mL/kg actual body D. Tidal volume 8 mL/kg ideal body weight
weight with high PEEP to maintain SpO2 > with low PEEP and high FiO2
95%
Correct: B - Tidal volume 6 mL/kg ideal body weight with plateau pressure < 30 cm H2O
and permissive hypercapnia
Rationale:Low tidal volume ventilation (6 mL/kg ideal body weight) with plateau pressure <
30 cm H2O is the evidence-based standard for ARDS to minimize volutrauma and
barotrauma. Permissive hypercapnia is accepted to achieve this goal. High tidal volumes
(options A and C) increase lung injury; option D uses low PEEP which may not be sufficient
for oxygenation.

Q3.
A patient with end-stage renal disease on hemodialysis is prescribed erythropoietin.
Which laboratory value is most critical to monitor to prevent a serious adverse effect?
A. Serum potassium B. Hemoglobin level
C. Serum ferritin D. Blood urea nitrogen
Correct: B - Hemoglobin level
Rationale:Erythropoietin stimulates red blood cell production; monitoring hemoglobin is
essential to avoid excessive levels that increase the risk of thromboembolic events. The
target hemoglobin is typically 10-11 g/dL. Potassium and BUN are important in renal failure
but not directly related to erythropoietin's major adverse effect. Ferritin is monitored to ensure
adequate iron stores but is not the most critical for safety.
Q4.
A patient with cirrhosis and ascites develops acute confusion, asterixis, and a serum
ammonia level of 80 mcg/dL. Which intervention is most likely to reduce ammonia
production?
A. Administering lactulose orally or via B. Administering rifaximin orally
nasogastric tube
C. Restricting dietary protein to 0.5 g/kg/day D. Administering neomycin enemas
Correct: A - Administering lactulose orally or via nasogastric tube
Rationale:Lactulose works by acidifying the colon, trapping ammonia and promoting its
excretion in stool, thus reducing systemic ammonia levels. Rifaximin reduces
ammonia-producing bacteria but is not the first-line immediate intervention. Protein restriction
is controversial and not the primary treatment for acute hepatic encephalopathy. Neomycin
enemas are less commonly used due to nephrotoxicity and ototoxicity.
Q5.
Which of the following assessment findings in a patient with a pulmonary embolism (PE)
would most strongly indicate the need for immediate thrombolytic therapy?
A. Heart rate of 118 beats/min and B. Systolic blood pressure of 90 mm Hg and
respiratory rate of 24 breaths/min evidence of right ventricular dysfunction on
echocardiography
C. Oxygen saturation of 91% on room air D. Elevated troponin level and sinus
and pleuritic chest pain tachycardia
Correct: B - Systolic blood pressure of 90 mm Hg and evidence of right ventricular
dysfunction on echocardiography
