,Q1. A patient admitted with acute pancreatitis develops sudden onset of respiratory distress,
cyanosis, and a drop in oxygen saturation to 85%. Arterial blood gas reveals PaO2 55
mmHg, PaCO2 30 mmHg, pH 7.48. Chest X-ray shows bilateral diffuse infiltrates. Which
pathophysiological mechanism most likely explains this presentation?
A. Activation of pancreatic enzymes leading to surfactant degradation and alveolar collapse
B. Systemic inflammatory response syndrome causing increased pulmonary capillary
permeability
C. Pulmonary embolism from splenic vein thrombosis secondary to pancreatitis
D. Aspiration of gastric contents due to paralytic ileus and vomiting
Correct Answer: B. Systemic inflammatory response syndrome causing increased
pulmonary capillary permeability
Rationale: The patient is exhibiting acute respiratory distress syndrome (ARDS), a common
complication of severe pancreatitis due to systemic inflammatory response syndrome (SIRS). SIRS
leads to increased pulmonary capillary permeability, causing noncardiogenic pulmonary edema.
Surfactant degradation is not a direct consequence of pancreatitis; pulmonary embolism and
aspiration are less likely given the bilateral infiltrates and absence of focal findings.
Why Wrong:
A - Pancreatic enzymes do not directly degrade surfactant; ARDS in pancreatitis is primarily
due to inflammatory mediators.
C - Pulmonary embolism typically presents with unilateral pleuritic pain and hemoptysis, not
bilateral infiltrates.
D - Aspiration pneumonitis would likely show localized infiltrates, not diffuse bilateral
involvement.

Q2. A patient with chronic kidney disease (CKD) stage 5 on hemodialysis is prescribed
sevelamer carbonate 800 mg three times daily with meals. The patient asks why this
medication must be taken with food. Which response best explains the rationale?
A. Sevelamer binds to dietary phosphate in the gastrointestinal tract, reducing absorption
when taken with meals.
B. Food increases the bioavailability of sevelamer, enhancing its phosphate-binding efficacy.
C. Taking sevelamer with meals minimizes gastrointestinal side effects such as nausea and
dyspepsia.
D. Sevelamer requires gastric acid for activation, which is stimulated by food intake.
Correct Answer: A. Sevelamer binds to dietary phosphate in the gastrointestinal tract,
reducing absorption when taken with meals.
Rationale: Sevelamer is a phosphate binder that works by binding to phosphate in the
gastrointestinal tract, preventing its absorption. It must be taken with meals to be present at the
same time as dietary phosphate. Bioavailability is not increased by food; side effects are not the
primary reason for timing; and sevelamer does not require gastric acid for activation.
Page 3
, Why Wrong:
B - Sevelamer works by binding phosphate in the gut, not by increased bioavailability.
C - While taking with meals may reduce GI upset, the primary rationale is phosphate
binding.
D - Sevelamer does not require gastric acid; it is effective across a range of pH.
