,Section A - Chronic
Q1.
In a patient with chronic heart failure, which compensatory mechanism initially maintains
cardiac output but ultimately contributes to disease progression by increasing afterload
and promoting ventricular remodeling?
A. Upregulation of beta-1 adrenergic B. Activation of the
receptors renin-angiotensin-aldosterone system
C. Increased atrial natriuretic peptide D. Enhanced parasympathetic tone
secretion
Correct: B - Activation of the renin-angiotensin-aldosterone system
Rationale:RAAS activation increases systemic vascular resistance (afterload) and causes
sodium retention, leading to volume overload and fibrosis. Beta-receptor downregulation, not
upregulation, occurs. ANP initially counteracts but is overwhelmed. Parasympathetic tone is
not a compensatory mechanism in heart failure.
Q2.
Which pathophysiological mechanism best explains the development of metabolic
alkalosis in a patient with severe vomiting?
A. Loss of hydrogen ions and chloride from B. Hypokalemia-induced shift of hydrogen
gastric fluid ions into cells
C. Increased renal bicarbonate reabsorption D. All of the above
due to secondary hyperaldosteronism
Correct: D - All of the above
Rationale:Vomiting causes loss of H+ and Cl- directly, leading to alkalosis. Hypokalemia
shifts H+ intracellularly, exacerbating the alkalosis. Volume depletion stimulates aldosterone,
increasing bicarbonate reabsorption. Thus all mechanisms contribute.
Q3.
A patient with type 1 diabetes mellitus develops diabetic ketoacidosis. Which combination
of laboratory findings is most consistent with this condition?
A. pH 7.25, bicarbonate 12 mEq/L, anion B. pH 7.50, bicarbonate 30 mEq/L, anion
gap 20, serum ketones positive gap 8, serum ketones negative
C. pH 7.35, bicarbonate 22 mEq/L, anion D. pH 7.40, bicarbonate 24 mEq/L, anion
gap 10, serum ketones negative gap 12, serum ketones negative
Correct: A - pH 7.25, bicarbonate 12 mEq/L, anion gap 20, serum ketones positive
Page 3
, Section A - Chronic
Rationale: DKA is characterized by metabolic acidosis with elevated anion gap and positive
ketones. Option A shows low pH, low bicarbonate, high anion gap, and ketonemia. Other
options reflect normal or alkalotic states.
Q4.
A patient with chronic kidney disease has a serum calcium of 8.0 mg/dL and phosphorus
of 6.5 mg/dL. Which secondary response is most likely to occur?
A. Decreased parathyroid hormone B. Increased calcitriol synthesis
secretion
C. Increased fibroblast growth factor 23 D. Decreased bone resorption
(FGF-23) secretion
Correct: C - Increased fibroblast growth factor 23 (FGF-23) secretion
Rationale:In CKD, hyperphosphatemia stimulates FGF-23 secretion, which inhibits calcitriol
synthesis and causes hypocalcemia. PTH is elevated, not decreased. Calcitriol synthesis is
decreased, and bone resorption is increased, not decreased.
Q5.
Which pathophysiological process distinguishes acute respiratory distress syndrome
(ARDS) from cardiogenic pulmonary edema?
A. Increased hydrostatic pressure in B. Damage to the alveolar-capillary
pulmonary capillaries membrane leading to increased permeability
C. Decreased oncotic pressure due to D. Lymphatic obstruction causing fluid
hypoalbuminemia accumulation
Correct: B - Damage to the alveolar-capillary membrane leading to increased permeability
Rationale:ARDS is characterized by inflammatory damage to the alveolar-capillary
membrane, causing protein-rich edema. Cardiogenic edema results from increased
hydrostatic pressure. Hypoalbuminemia and lymphatic obstruction are less common causes,
not the hallmark.
Q6.
A patient with cirrhosis develops ascites. Which combination of pathophysiological
mechanisms contributes to fluid accumulation in the peritoneal cavity?
A. Portal hypertension and decreased B. Increased aldosterone secretion and
hepatic albumin synthesis lymphatic drainage
C. Reduced splanchnic vasodilation and low D. Enhanced renal perfusion and increased
renin levels natriuresis
