SECTION ONE: QUESTIONS 1–100
A patient with a history of chronic obstructive pulmonary disease (COPD) presents with lethargy and a pH of 7.28. Which acid-base
imbalance is likely?
A. Metabolic alkalosis
B. Respiratory acidosis
C. Respiratory alkalosis
D. Metabolic acidosis
🟢 B. Option B
🔴 RATIONALE: COPD patients often have CO2 retention (hypercapnia), which leads to respiratory acidosis due to impaired gas
exchange.
Which process best describes the shift of cells to a more primitive, undifferentiated state, often associated with malignancy?
A. Hypertrophy
B. Hyperplasia
C. Anaplasia
D. Metaplasia
,🟢 C. Option C
🔴 RATIONALE: Anaplasia refers to the loss of cellular differentiation and is a hallmark of cancerous cells.
During an inflammatory response, which cells are the first to arrive at the site of injury?
A. Macrophages
B. Neutrophils
C. T-lymphocytes
D. Basophils
🟢 B. Option B
🔴 RATIONALE: Neutrophils are the primary phagocytic cells that arrive first (within 6-12 hours) to combat bacterial infection and
injury.
Which laboratory marker is most specific for diagnosing myocardial infarction?
A. Myoglobin
B. Troponin I
C. Creatine Kinase (CK-MB)
D. Lactate Dehydrogenase (LDH)
🟢 B. Option B
🔴 RATIONALE: Cardiac-specific troponins (Troponin I and T) are the gold standard markers for myocardial injury due to their high
sensitivity and specificity.
What is the primary role of the Renin-Angiotensin-Aldosterone System (RAAS) in fluid volume regulation?
A. Vasodilation to increase blood flow
B. Excretion of sodium and water
C. Retention of sodium and water to increase blood pressure
D. Inhibition of ADH secretion
🟢 C. Option C
🔴 RATIONALE: RAAS activation results in aldosterone release, which promotes sodium and water reabsorption in the kidneys,
thereby increasing blood pressure.
A client with Graves’ disease is expected to have which serum laboratory result?
A. High TSH, Low T3/T4
B. Low TSH, High T3/T4
C. High TSH, High T3/T4
D. Low TSH, Low T3/T4
🟢 B. Option B
, 🔴 RATIONALE: Graves' disease is hyperthyroidism; high levels of circulating thyroid hormones (T3/T4) suppress pituitary TSH
production via negative feedback.
Which type of shock is caused by a severe systemic hypersensitivity reaction?
A. Septic
B. Neurogenic
C. Anaphylactic
D. Hypovolemic
🟢 C. Option C
🔴 RATIONALE: Anaphylactic shock occurs due to a massive release of histamine and other mediators in response to an allergen,
causing systemic vasodilation and increased capillary permeability.
In a client with Type 2 Diabetes, which pathophysiological finding is central to the disease?
A. Total absence of insulin production
B. Peripheral tissue resistance to insulin
C. Destruction of pancreatic alpha cells
D. Increased hepatic sensitivity to insulin
🟢 B. Option B
🔴 RATIONALE: Type 2 Diabetes is primarily driven by insulin resistance in peripheral tissues and a relative deficiency in insulin
secretion.
Which electrolyte imbalance is most commonly associated with muscle tetany and a positive Chvostek sign?
A. Hypernatremia
B. Hypokalemia
C. Hypocalcemia
D. Hypermagnesemia
🟢 C. Option C
🔴 RATIONALE: Low serum calcium increases neuromuscular excitability, leading to tetany and positive Chvostek or Trousseau signs.
A client is diagnosed with a benign tumor. What feature characterizes this tumor compared to a malignant one?
A. Metastasis to distant organs
B. Rapid growth with irregular borders
C. Encapsulated and well-differentiated
D. Invasive into surrounding tissues
🟢 C. Option C
