Batch 1: Cardiovascular & Renal Systems (Q 1–25)
1. A patient with heart failure is prescribed an ACE inhibitor. Which physiological
mechanism explains the reduction in cardiac workload?
A) Increasing systemic vascular resistance
B) Inhibiting the conversion of Angiotensin I to II, reducing preload and afterload
C) Direct stimulation of beta-1 adrenergic receptors
D) Promoting potassium excretion in the distal tubule
ACE inhibitors block the production of Angiotensin II, a potent vasoconstrictor. This
leads to vasodilation (reduced afterload) and decreased aldosterone secretion, which
lowers sodium/water retention (reduced preload).
2. In Chronic Kidney Disease (CKD), why do patients develop secondary
hyperparathyroidism?
A) Overproduction of erythropoietin
B) Hypocalcemia caused by phosphate retention and impaired Vitamin D
activation
C) Direct damage to the parathyroid glands from urea
D) Excessive filtration of calcium in the glomerulus
Failing kidneys cannot excrete phosphorus or convert Vitamin D to its active form
(calcitriol). High phosphorus levels bind to calcium, causing hypocalcemia, which
triggers the parathyroid glands to release excess PTH.
3. What is the hallmark of Right-Sided Heart Failure (Cor Pulmonale)
pathophysiology?
A) Pulmonary edema and paroxysmal nocturnal dyspnea
B) Systemic venous congestion, hepatomegaly, and peripheral edema
, C) Decreased cardiac output to the cerebral cortex
D) Left ventricular hypertrophy
When the right ventricle fails, blood backs up into the systemic venous system, leading
to jugular venous distention (JVD), liver engorgement, and dependent edema.
4. Which medication is considered first-line for a patient with Prinzmetal (variant)
angina?
A) Metoprolol
B) Calcium Channel Blockers (e.g., Amlodipine)
C) High-dose Aspirin
D) Lisinopril
Prinzmetal angina is caused by coronary artery vasospasm rather than plaque.
Calcium channel blockers promote vasodilation and prevent spasms, whereas beta-
blockers are generally avoided as they can lead to unopposed alpha-vasoconstriction.
5. A patient is prescribed Spironolactone for heart failure. Which cellular electrolyte
shift must the provider monitor?
A) Hypokalemia
B) Hyperkalemia due to antagonism of aldosterone in the collecting duct
C) Metabolic alkalosis
D) Hypernatremia
Spironolactone is a potassium-sparing diuretic. It blocks aldosterone receptors, which
normally promote sodium reabsorption and potassium excretion; blocking this results in
potassium retention.
Batch 2: Endocrine & Metabolic Systems (Q 26–50)
6. Pathophysiologically, how does Type 2 Diabetes Mellitus differ from Type
1?
A) Type 2 involves absolute insulin deficiency
B) Type 2 involves peripheral insulin resistance and progressive beta-cell
dysfunction
C) Type 1 is caused by a high-sugar diet
D) Type 2 is strictly an autoimmune disorder
Type 1 is characterized by autoimmune destruction of beta cells (no insulin). Type 2 is
a complex state where tissues do not respond effectively to insulin (resistance), and the
pancreas eventually fails to keep up with demand.
, 7. A patient with Graves' Disease (Hyperthyroidism) is prescribed
Propylthiouracil (PTU). What is its mechanism of action?
A) Stimulating the thyroid gland to store more iodine
B) Inhibiting thyroid hormone synthesis and preventing peripheral conversion of
T4 to T3
C) Blocking TSH receptors in the pituitary
D) Increasing the metabolic rate to burn off excess hormone
PTU interferes with the enzyme thyroid peroxidase to block hormone production and
prevents the conversion of the pro-hormone T4 into the more potent T3 in the body's
tissues.
8. What is the primary electrolyte abnormality in SIADH?
A) Hypernatremia
B) Dilutional Hyponatremia
C) Hypokalemia
D) Hypercalcemia
SIADH involves excessive Antidiuretic Hormone (ADH) release, which causes the
kidneys to reabsorb water excessively. This water retention dilutes the serum sodium
level, leading to hyponatremia.
9. In Cushing’s Syndrome, the presence of "buffalo hump" and "moon face"
is due to:
A) Muscle hypertrophy from high protein intake
B) Cortisol-mediated lipogenesis and fat redistribution
C) Water retention from high potassium levels
D) Hypoglycemia-induced hunger
Excess glucocorticoids (cortisol) cause a distinct pattern of truncal obesity and fat
deposition in the face and cervicodorsal area while simultaneously causing muscle
wasting in the extremities.
10. Which medication class carries a Black Box warning for patients with a
history of medullary thyroid carcinoma?
A) Biguanides (Metformin)
B) GLP-1 Receptor Agonists (e.g., Liraglutide)
C) SGLT-2 Inhibitors
D) Sulfonylureas
