SECTION A: Core Pathophysiology & Pharmacology Principles (32 Marks)
Question: 1
A patient is prescribed a medication that is known to undergo extensive first-pass
metabolism. Which route of administration would best avoid this phenomenon and ensure
maximum bioavailability?
Options:
A) Oral
B) Sublingual
C) Enteral
D) Rectal (lower hemorrhoidal veins)
Correct Answer: B
Marks: 4
Rationale: Sublingual administration allows the drug to be absorbed directly into the
systemic circulation via the rich vascular network under the tongue, bypassing the hepatic
portal system. This avoids first-pass metabolism, ensuring higher bioavailability compared to
oral or standard enteral routes.
, Question: 2
A pharmacological agent binds to a specific receptor site but does not activate it, instead
preventing the endogenous ligand from binding. What is the correct classification of this
agent?
Options:
A) Full agonist
B) Partial agonist
C) Competitive antagonist
D) Allosteric modulator
Correct Answer: C
Marks: 4
Rationale: A competitive antagonist binds reversibly to the same receptor site as the
endogenous ligand without activating it, thereby blocking the ligand's effect. This
competition can be overcome by increasing the concentration of the endogenous agonist.
Question: 3
In the pathophysiology of heart failure, decreased cardiac output triggers a compensatory
neurohormonal response. Which of the following is a direct result of Renin-Angiotensin-
Aldosterone System (RAAS) activation?
Options:
A) Vasodilation and decreased blood pressure
B) Sodium and water retention leading to increased preload
C) Decreased sympathetic nervous system activity
D) Increased excretion of potassium and magnesium
Correct Answer: B
Marks: 4
Rationale: RAAS activation leads to the production of angiotensin II (a potent
vasoconstrictor) and aldosterone (which promotes sodium and water reabsorption in the
kidneys). This increases blood volume and preload, initially compensating for low cardiac
output but eventually worsening heart failure.
Question: 4
Which pathophysiological mechanism is the primary hallmark of Type 2 Diabetes Mellitus?
Options:
A) Autoimmune destruction of pancreatic beta cells
B) Absolute deficiency of insulin production
C) Peripheral insulin resistance and relative insulin deficiency
D) Excessive glucagon-like peptide-1 (GLP-1) secretion
Correct Answer: C
Marks: 4
Rationale: Type 2 Diabetes Mellitus is primarily characterized by peripheral insulin
resistance, where target cells fail to respond normally to insulin, coupled with a relative
insulin deficiency as beta cells eventually fail to compensate. This contrasts with Type 1
Diabetes, which involves absolute insulin deficiency due to autoimmune destruction.
