Section One: Questions 1–100
A patient presents with hyperthyroidism symptoms and a suppressed TSH level. Which diagnostic
finding would confirm Graves disease as the etiology?
A. Elevated thyroglobulin levels
B. Presence of thyroid-stimulating immunoglobulins
,C. Decreased uptake on thyroid scan
D. Positive antithyroid peroxidase antibodies
🟢 B. Presence of thyroid-stimulating immunoglobulins
🔴 Explanation: Graves disease is an autoimmune disorder where thyroid-stimulating immunoglobulins bind
to TSH receptors, causing unregulated production of thyroid hormones.
A 55-year-old patient with type 2 diabetes presents with a non-healing foot ulcer. Which
pathophysiological factor is the primary contributor to this complication?
A. Macrovascular insufficiency only
B. Peripheral neuropathy and impaired leukocyte function
C. Hyperinsulinemia-induced vasoconstriction
D. Excessive collagen synthesis in the dermis
🟢 B. Peripheral neuropathy and impaired leukocyte function
🔴 Explanation: Diabetic foot ulcers result from a combination of neuropathy (loss of sensation leading to
trauma) and immune dysfunction (impaired phagocytosis).
In the context of syndrome of inappropriate antidiuretic hormone (SIADH), which electrolyte abnormality
is the expected clinical finding?
A. Hypernatremia
B. Hypokalemia
C. Hyponatremia
D. Hypercalcemia
🟢 C. Hyponatremia
🔴 Explanation: SIADH leads to excess water retention due to unregulated ADH release, resulting in dilutional
hyponatremia.
When assessing a patient for pheochromocytoma, which clinical presentation is most classic?
A. Bradycardia, weight gain, and cold intolerance
B. Episodic hypertension, diaphoresis, and tachycardia
C. Hypotension, bronze skin pigmentation, and salt craving
D. Polyuria, polydipsia, and polyphagia
,🟢 B. Episodic hypertension, diaphoresis, and tachycardia
🔴 Explanation: Pheochromocytoma is a catecholamine-secreting tumor causing the classic triad of
headache, sweating, and tachycardia associated with hypertensive episodes.
A patient with suspected Cushing syndrome exhibits buffalo hump and moon facies. Which hormonal
profile is most indicative of this condition?
A. Low ACTH, low cortisol
B. High ACTH, high cortisol
C. Low ACTH, high cortisol
D. High ACTH, low cortisol
🟢 C. Low ACTH, high cortisol
🔴 Explanation: In adrenal Cushing syndrome (primary), cortisol is autonomous, and high levels suppress
pituitary ACTH via negative feedback.
Which laboratory finding is diagnostic for disseminated intravascular coagulation (DIC)?
A. Decreased D-dimer levels
B. Elevated fibrinogen levels
C. Increased prothrombin time (PT) and decreased fibrinogen
D. Increased platelet count
🟢 C. Increased prothrombin time (PT) and decreased fibrinogen
🔴 Explanation: DIC is characterized by systemic clotting depletion, leading to consumption of clotting factors
like fibrinogen and prolongation of PT/PTT.
A patient with Multiple Sclerosis presents with a new onset of optic neuritis. What is the underlying
pathophysiology?
A. Peripheral nerve demyelination
B. Central nervous system demyelination
C. Neuromuscular junction blockade
D. Degeneration of lower motor neurons
, 🟢 B. Central nervous system demyelination
🔴 Explanation: Multiple Sclerosis is an autoimmune-mediated demyelinating disease primarily affecting the
white matter of the central nervous system.
Regarding the legal requirements for charting, which action represents a violation of professional
standards in an acute care setting?
A. Documenting objectively based on physical assessment
B. Modifying a previous entry by drawing a single line and initialing
C. Documenting a co-worker's procedure that you did not witness
D. Using standardized medical terminology
🟢 C. Documenting a co-worker's procedure that you did not witness
🔴 Explanation: Professional standards dictate that a practitioner should only document actions they have
performed or witnessed, as documenting for others is a legal risk.
Which mechanism explains the development of secondary hyperparathyroidism in chronic kidney
disease?
A. Increased renal excretion of phosphate
B. Impaired conversion of Vitamin D to its active form
C. Autonomous secretion of PTH by the parathyroid glands
D. Excessive intake of calcium supplements
🟢 B. Impaired conversion of Vitamin D to its active form
🔴 Explanation: The kidneys are responsible for activating Vitamin D; failure to do so leads to decreased
calcium absorption and subsequent compensatory PTH elevation.
A patient exhibits symptoms of iron deficiency anemia. Which blood smear finding is most consistent?
A. Macrocytic, normochromic
B. Microcytic, hypochromic
C. Normocytic, normochromic
D. Microcytic, hyperchromic
