SECTION ONE: QUESTIONS 1–100
A patient presents with localized redness, heat, and edema following a laceration. Which chemical
mediator is primarily responsible for the vasodilation observed in this inflammatory response?
A. Histamine
B. Complement C3b
C. Interleukin-1
,D. Prostaglandin
🟢 A. Histamine
🔴 RATIONALE: Histamine is released by mast cells during the initial phase of inflammation,
causing rapid vasodilation and increased capillary permeability.
Which diagnostic finding is most indicative of a left-sided heart failure exacerbation?
A. Jugular venous distention
B. Bilateral pitting pedal edema
C. Crackles on pulmonary auscultation
D. Hepatomegaly
🟢 C. Crackles on pulmonary auscultation
🔴 RATIONALE: Left-sided heart failure causes pulmonary venous congestion, leading to fluid
backup in the lungs, manifested by crackles.
A patient with type 1 diabetes mellitus is found unconscious with a blood glucose of 45 mg/dL.
Which pathophysiological mechanism is occurring?
A. Ketoacidosis
B. Hyperosmolar hyperglycemic state
C. Neuroglycopenia
D. Somogyi effect
🟢 C. Neuroglycopenia
🔴 RATIONALE: Severe hypoglycemia leads to a glucose deficit in the brain, causing altered
consciousness known as neuroglycopenia.
Which stage of the General Adaptation Syndrome is characterized by the mobilization of the
sympathetic nervous system and the "fight-or-flight" response?
A. Resistance
B. Exhaustion
,C. Alarm
D. Recovery
🟢 C. Alarm
🔴 RATIONALE: The alarm stage is the initial phase of stress, activating the hypothalamic-pituitary-
adrenal axis and sympathetic responses.
A patient with chronic kidney disease (CKD) develops severe pruritus and uremic frost. This is a
manifestation of:
A. Hyperkalemia
B. Azotemia
C. Metabolic alkalosis
D. Renal calculi
🟢 B. Azotemia
🔴 RATIONALE: Azotemia refers to the accumulation of nitrogenous waste products in the blood,
which can manifest as uremic frost on the skin.
Which laboratory result would be expected in a patient experiencing primary hyperparathyroidism?
A. Hypocalcemia
B. Hypercalcemia
C. Hypophosphatemia
D. Both B and C
🟢 D. Both B and C
🔴 RATIONALE: Excess parathyroid hormone causes bone resorption (releasing calcium) and renal
phosphate excretion.
Which patient is at the highest risk for developing hospital-acquired pneumonia?
A. A patient on mechanical ventilation
B. A patient with a nasogastric tube
, C. A patient post-laparoscopic surgery
D. A patient with community-acquired influenza
🟢 A. A patient on mechanical ventilation
🔴 RATIONALE: Mechanical ventilation bypasses natural airway defenses, significantly increasing
the risk of ventilator-associated pneumonia.
In a patient with meningitis, which finding is most consistent with meningeal irritation?
A. Trousseau sign
B. Kernig sign
C. Babinski sign
D. Chvostek sign
🟢 B. Kernig sign
🔴 RATIONALE: Kernig sign is positive when the patient experiences pain and resistance upon
knee extension while the hip is flexed, indicating meningeal inflammation.
Which immunoglobulin is the first to be produced during the primary immune response?
A. IgG
B. IgE
C. IgM
D. IgA
🟢 C. IgM
🔴 RATIONALE: IgM is the largest immunoglobulin and the first responder in the primary immune
response to an antigen.
A patient exhibits signs of Cushing syndrome. Which hormonal imbalance is the primary cause?
A. Excess cortisol
B. Deficit of aldosterone
C. Excess growth hormone
