,Q1. A patient with chronic hyperglycemia and poor glycemic control presents with
polyuria, polydipsia, and unintentional weight loss despite increased appetite.
Laboratory tests reveal hyperglycemia (fasting glucose > 250 mg/dL) and elevated
serum ketones. Which pathophysiologic mechanism is most directly responsible for
the development of polyuria in this condition?
A. Increased osmotic drag in the proximal tubule due to glucose-mediated diuresis
B. Reduced secretion of antidiuretic hormone (ADH) from the posterior pituitary
C. Increased serum osmolality directly inhibiting sodium reabsorption in the collecting
duct
D. Overactivation of the renin-angiotensin-aldosterone system secondary to
hypovolemia
Correct Answer: A. Increased osmotic drag in the proximal tubule due to
glucose-mediated diuresis
Rationale: Polyuria in uncontrolled diabetes mellitus (likely type 1 with ketosis) results
from osmotic diuresis: high filtered glucose exceeds the tubular reabsorptive capacity,
drawing water into the urine via osmotic drag in the proximal tubule. Option B (ADH
deficiency) would cause diabetes insipidus, not hyperglycemia. Option C incorrectly
describes direct inhibition of sodium reabsorption, and option D is a secondary response,
not the primary cause.
Why Wrong:
B - ADH deficiency causes diabetes insipidus, characterized by low urine osmolality
and no hyperglycemia.
C - Elevated serum osmolality does not directly inhibit sodium reabsorption; osmotic
diuresis is due to glucose in the tubular lumen.
D - RAAS activation may occur from hypovolemia but is a compensatory mechanism,
not the proximate cause of polyuria.

Q2. A patient with Cushing's syndrome exhibits central obesity, muscle wasting, and
glucose intolerance. Which molecular mechanism best explains the catabolic effects
on skeletal muscle?
A. Cortisol-induced translocation of GLUT4 transporters to the sarcolemma
B. Inhibition of ubiquitin-proteasome pathway by glucocorticoid receptor binding
C. Suppression of myostatin transcription leading to increased protein synthesis
D. Activation of the transcription factor FoxO, increasing autophagy and proteolysis
Correct Answer: D. Activation of the transcription factor FoxO, increasing
autophagy and proteolysis
Page 3
, Rationale: Cortisol promotes muscle atrophy by upregulating FoxO transcription factors,
which drive the expression of atrogin-1 and MuRF1 (E3 ubiquitin ligases) and stimulate
autophagy, leading to protein breakdown. Option A is incorrect because cortisol reduces
GLUT4 translocation. Option B is wrong; cortisol enhances, not inhibits, the
ubiquitin-proteasome pathway. Option C is incorrect; myostatin is increased by
glucocorticoids, not suppressed.
Why Wrong:
A - Cortisol impairs GLUT4 translocation, causing insulin resistance, not increased
glucose uptake.
B - Glucocorticoids activate the ubiquitin-proteasome pathway, promoting muscle
proteolysis.
C - Myostatin expression is upregulated by glucocorticoids, contributing to muscle
wasting.

Q3. A patient with decompensated heart failure presents with dyspnea, orthopnea,
and bilateral leg edema. Physical exam reveals crackles in the lung bases, distended
neck veins, and hepatomegaly. Which combination of hemodynamic findings is most
consistent with this presentation?
A. Elevated pulmonary capillary wedge pressure (PCWP), decreased left ventricular
end-diastolic volume (LVEDV), decreased cardiac output
B. Elevated PCWP, increased LVEDV, decreased cardiac output
C. Decreased PCWP, decreased LVEDV, decreased cardiac output
D. Elevated PCWP, increased LVEDV, increased cardiac output
Correct Answer: B. Elevated PCWP, increased LVEDV, decreased cardiac output
Rationale: This presentation is classic for acute-on-chronic heart failure with left
ventricular systolic dysfunction. Elevated PCWP indicates increased left atrial pressure
from fluid overload. Increased LVEDV reflects preload excess due to reduced contractility,
and cardiac output is decreased. Option A is incorrect because LVEDV is usually
increased in systolic failure. Option C describes hypovolemia. Option D describes
high-output failure (e.g., sepsis, thyrotoxicosis).
Why Wrong:
A - LVEDV is increased in systolic heart failure, not decreased.
C - Decreased PCWP and LVEDV occur with hypovolemia, not pulmonary
congestion and edema.
D - Increased cardiac output is seen in high-output failure, not typical decompensated
heart failure.

Disease.' Ch. 1 & 7.
