PART 1: EXAM QUESTIONS
Section 1: Endocrine Pathophysiology: Thyroid, Adrenal, & Pancreatic
Disorders
Q1: A 28-year-old female presents with weight loss, heat intolerance, palpitations, tremor, and diffuse goiter.
TSH is suppressed at 0.05 mIU/mL and free T4 is elevated. Which pathophysiologic mechanism best explains
her thyrotoxicosis?
A. TSH-secreting pituitary adenoma causing secondary hyperthyroidism with elevated TSH and free T4
B. Autoimmune stimulation of TSH receptors by thyroid-stimulating immunoglobulins (Graves disease), causing
diffuse goiter and unregulated thyroid hormone synthesis with suppressed TSH via negative feedback
[CORRECT]
C. Subacute thyroiditis with follicular destruction releasing preformed thyroid hormone
D. Exogenous levothyroxine ingestion causing factitious hyperthyroidism
Correct Answer: B
Rationale: Graves disease is the most common cause of hyperthyroidism in young women: TSI (IgG autoantibodies)
activate TSH receptors, stimulating follicular hypertrophy (diffuse goiter) and excess T3/T4 synthesis, suppressing TSH.
Option A would present with elevated (not suppressed) TSH. Option C causes transient thyrotoxicosis with painful
thyroid. Option D is factitious, without goiter or TSI.
Q2: A 45-year-old female with untreated Graves disease presents with fever (104.2 F), tachycardia (150 bpm),
agitation, and altered mental status. Which pathophysiologic cascade describes thyroid storm?
A. Gradual increase in thyroid hormone production over weeks with mild symptomatic progression
B. Acute surge of thyroid hormone release triggered by stressor (surgery, infection, iodine load), causing
excessive beta-adrenergic stimulation, hyperthermia from uncoupled oxidative phosphorylation, and multi-organ
decompensation [CORRECT]
C. Autoimmune destruction of thyroid follicles with release of stored hormone and subsequent permanent
hypothyroidism
D. Pituitary apoplexy with hemorrhagic infarction of a TSH-secreting adenoma
Correct Answer: B
Rationale: Thyroid storm is a life-threatening decompensation: a precipitating stressor causes massive release of T3/T4,
saturating binding proteins and dramatically increasing free hormone. Excess catecholamine sensitivity causes
tachyarrhythmias, hyperthermia (uncoupled mitochondrial oxidative phosphorylation), and CNS/GI decompensation.
Option A describes uncomplicated hyperthyroidism. Option C describes destructive thyroiditis. Option D is a pituitary
emergency, not thyroid storm.
Q3: A 52-year-old male with type 2 diabetes presents with glucose 840 mg/dL, serum osmolality 380
mOsm/kg, pH 7.32, and bicarbonate 20 mEq/L. Urine ketones are trace. Which diagnosis and pathophysiologic
mechanism are most accurate?
A. Diabetic ketoacidosis with absolute insulin deficiency and predominant ketone body production
B. Hyperosmolar hyperglycemic state (HHS) with relative insulin deficiency sufficient to suppress ketogenesis
but inadequate to prevent hyperglycemia, causing severe osmotic diuresis, profound dehydration, and
hyperosmolality [CORRECT]
C. Lactic acidosis from metformin accumulation with minimal hyperglycemia
D. Mixed DKA-HHS with equal contributions of ketosis and hyperosmolality
Correct Answer: B
Rationale: HHS is characterized by severe hyperglycemia (often >600 mg/dL), hyperosmolality (>320 mOsm/kg), and
minimal ketosis. Relative insulin deficiency (versus absolute in DKA) allows enough lipogenesis to suppress
hormone-sensitive lipase, preventing significant ketogenesis, but inadequate glucose utilization causes extreme
hyperglycemia and osmotic diuresis. Option A would show prominent ketonuria and metabolic acidosis. Option C
Page 2
, NUR 6111 Quiz 2 | William Paterson University | 2026 Update
features lactic acidosis with less hyperglycemia. Option D is rare and would show both significant ketosis and
hyperosmolality.
Q4: A 38-year-old female presents with hypotension, hyperpigmentation (palmar creases and buccal mucosa),
hyponatremia (126 mEq/L), hyperkalemia (6.1 mEq/L), and morning cortisol of 2.8 mcg/dL with elevated
ACTH. Which pathophysiologic mechanism explains her presentation?
A. Secondary adrenal insufficiency from pituitary ACTH deficiency with preserved aldosterone and absence of
hyperpigmentation
B. Conn syndrome (primary aldosteronism) with autonomous aldosterone secretion causing hypertension and
hypokalemia
C. Primary adrenal insufficiency (Addison disease) with autoimmune destruction of all adrenal cortex zones:
zona glomerulosa loss (aldosterone deficiency causing hyponatremia, hyperkalemia) and zona
fasciculata/reticularis loss (cortisol deficiency with elevated ACTH causing hyperpigmentation) [CORRECT]
D. Exogenous glucocorticoid use causing hypothalamic-pituitary-adrenal suppression with Cushingoid features
Correct Answer: C
Rationale: Primary adrenal insufficiency destroys all cortical zones: aldosterone deficiency (zona glomerulosa) impairs
renal Na+ reabsorption and K+ excretion (hyponatremia, hyperkalemia); cortisol deficiency (zona fasciculata) removes
negative feedback, elevating ACTH which stimulates melanocytes (hyperpigmentation). Option B describes Conn
syndrome (opposite electrolytes: hypernatremia, hypokalemia). Option A spares aldosterone (renin-angiotensin
regulated) and lacks hyperpigmentation. Option D causes secondary insufficiency, not primary.
Q5: A 42-year-old female presents with central obesity, moon facies, purple striae, hypertension,
hyperglycemia, and bruising. Midnight cortisol is elevated and fails to suppress with low-dose dexamethasone.
Which pathophysiologic process is most likely?
A. Primary adrenal insufficiency with decreased cortisol and elevated ACTH
B. Exogenous glucocorticoid administration causing iatrogenic Cushing syndrome
C. Autonomous cortisol overproduction from an ACTH-secreting pituitary adenoma (Cushing disease) causing
bilateral adrenal hyperplasia and loss of glucocorticoid negative feedback suppression [CORRECT]
D. Pheochromocytoma with catecholamine excess mimicking Cushing features
Correct Answer: C
Rationale: Cushing disease (pituitary ACTH-secreting adenoma) causes bilateral adrenal hyperplasia and cortisol
excess. Failure of low-dose dexamethasone suppression confirms pathological hypercortisolism. Features reflect
glucocorticoid excess (catabolism, hyperglycemia) and mineralocorticoid effects (hypertension). Option A has low
cortisol. Option B would suppress endogenous ACTH/cortisol. Option D causes episodic catecholamine surges, not
sustained hypercortisolism.
Q6: A 30-year-old female presents with galactorrhea, amenorrhea, and visual field defects (bitemporal
hemianopsia). MRI reveals a 1.2 cm pituitary macroadenoma. Prolactin level is 250 ng/mL. Which
pathophysiologic mechanism explains the endocrine findings?
A. Autoimmune hypophysitis with inflammatory destruction of all pituitary cell types
B. Prolactin-secreting pituitary macroadenoma compressing the optic chiasm (bitemporal hemianopsia) and
producing excess prolactin (galactorrhea, amenorrhea from suppression of GnRH) [CORRECT]
C. Hypothalamic dopaminergic excess suppressing all pituitary hormone secretion
D. Craniopharyngioma with suprasellar calcification causing panhypopituitarism
Correct Answer: B
Rationale: A prolactinoma is the most common functioning pituitary adenoma. Macroadenomas (>1 cm) compress the
optic chiasm (bitemporal hemianopsia) while excess prolactin inhibits GnRH pulsatility (amenorrhea) and stimulates
mammary epithelial cells (galactorrhea). Option A would cause panhypopituitarism with low prolactin. Option C would
suppress prolactin (dopamine inhibits prolactin). Option D is a developmental tumor, typically in children, causing
panhypopituitarism.
Q7: A 22-year-old male with type 1 diabetes presents with Kussmaul respirations, glucose 480 mg/dL, pH 7.12,
bicarbonate 6 mEq/L, anion gap 28, and positive urine ketones. Which pathophysiologic cascade best describes
