QUESTIONS AND 100% VERIFIED ANSWERS
WITH RATIONALES GRADED A+
Question 1
A patient with chronic hypertension develops left ventricular hypertrophy.
Which physiologic mechanism best explains this adaptation?
A. Increased preload leading to ventricular dilation
B. Increased afterload causing myocardial fiber thickening
C. Reduced coronary perfusion leading to ischemia
D. Decreased stroke volume causing compensatory tachycardia
Correct Answer: B
Rationale: Chronic hypertension increases systemic vascular resistance
(afterload). To overcome this pressure, myocardial fibers thicken (concentric
hypertrophy) to generate greater contractile force.
,Question 2
Which acid-base disturbance is most consistent with prolonged vomiting?
A. Metabolic acidosis
B. Respiratory acidosis
C. Metabolic alkalosis
D. Respiratory alkalosis
Correct Answer: C
Rationale: Vomiting results in loss of gastric hydrochloric acid, leading to
increased bicarbonate levels and metabolic alkalosis.
Question 3
A patient with type 2 diabetes presents with polyuria and polydipsia. Which
mechanism primarily causes these symptoms?
A. Insulin resistance at peripheral receptors
B. Increased hepatic gluconeogenesis
C. Osmotic diuresis from hyperglycemia
,D. Reduced antidiuretic hormone secretion
Correct Answer: C
Rationale: Elevated blood glucose exceeds renal reabsorption capacity,
causing glucose to spill into urine and pull water with it, resulting in osmotic
diuresis.
Question 4
Which finding is most characteristic of systolic heart failure?
A. Preserved ejection fraction
B. Ventricular wall thickening
C. Reduced cardiac contractility
D. Increased ventricular compliance
Correct Answer: C
Rationale: Systolic heart failure is defined by impaired myocardial
contractility and reduced ejection fraction.
Question 5
, A patient with chronic kidney disease develops secondary
hyperparathyroidism. What is the primary cause?
A. Increased calcium absorption
B. Excess vitamin D activation
C. Phosphate retention and hypocalcemia
D. Elevated calcitonin secretion
Correct Answer: C
Rationale: Impaired phosphate excretion leads to hyperphosphatemia,
which lowers serum calcium and stimulates parathyroid hormone release.
Question 6
Which immune response is primarily responsible for allergic reactions?
A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
Correct Answer: A
Rationale: Type I hypersensitivity is IgE-mediated and responsible for
immediate allergic reactions such as anaphylaxis and urticaria.
