Q1.
In a cell, a mutation in the gene encoding the regulatory subunit of protein kinase A (PKA)
renders it unable to bind cAMP. Which downstream effect is most likely to be impaired?
A. Phosphorylation of glycogen B. Activation of adenylyl cyclase
phosphorylase kinase
C. Hydrolysis of GTP by Gs alpha subunit D. Binding of epinephrine to beta-adrenergic
receptor
Correct: A - Phosphorylation of glycogen phosphorylase kinase
Rationale:PKA is activated by cAMP; if the regulatory subunit cannot bind cAMP, PKA
remains inactive, so it cannot phosphorylate downstream targets like glycogen phosphorylase
kinase. Adenylyl cyclase activation and GTP hydrolysis occur upstream of PKA, and receptor
binding is independent of PKA.
Q2.
A research study examines a tissue with chronic inflammation. Which cellular adaptation
is most likely to be observed in response to persistent cell injury?
A. Hypertrophy B. Dysplasia
C. Metaplasia D. Atrophy
Correct: C - Metaplasia
Rationale:Metaplasia is a reversible change where one adult cell type is replaced by another,
often due to chronic irritation. Hypertrophy is an increase in cell size, atrophy is a decrease,
and dysplasia is disordered growth often preneoplastic.
Q3.
Which of the following best describes the mechanism of action of loop diuretics in
treating edema?
A. Inhibition of Na+-K+-2Cl- cotransporter in B. Antagonism of aldosterone in the
the thick ascending limb collecting duct
C. Inhibition of carbonic anhydrase in the D. Blockade of sodium channels in the distal
proximal tubule convoluted tubule

Correct: A - Inhibition of Na+-K+-2Cl- cotransporter in the thick ascending limb
Rationale:Loop diuretics inhibit the Na+-K+-2Cl- cotransporter in the thick ascending limb of
the loop of Henle, causing potent diuresis. Aldosterone antagonists act in the collecting duct,
carbonic anhydrase inhibitors in the proximal tubule, and thiazides in the distal convoluted
tubule.
Q4.
A patient with chronic liver disease presents with jaundice and prolonged prothrombin
time. Which laboratory finding is most consistent with the pathophysiological
mechanism?
A. Decreased serum albumin and increased B. Elevated conjugated bilirubin and normal
serum ammonia unconjugated bilirubin
C. Increased serum creatinine and D. Elevated serum lipase and amylase
decreased GFR
Correct: A - Decreased serum albumin and increased serum ammonia
Rationale:Chronic liver disease impairs synthetic function, leading to decreased albumin and
clotting factors (prolonged PT), and impaired urea cycle increases ammonia. Conjugated
hyperbilirubinemia is more typical of biliary obstruction, while renal and pancreatic markers
are not directly related to liver synthetic dysfunction.
Q5.
A patient with a history of chronic obstructive pulmonary disease (COPD) develops cor
pulmonale. Which of the following is the most direct cause?
A. Pulmonary vasoconstriction leading to B. Systemic hypertension causing left
increased right ventricular afterload ventricular hypertrophy
C. Increased pulmonary blood flow due to D. Myocardial ischemia due to coronary
left-to-right shunt artery disease
Correct: A - Pulmonary vasoconstriction leading to increased right ventricular afterload
Rationale:COPD causes hypoxemia and hypercapnia, leading to pulmonary vasoconstriction
and increased pulmonary vascular resistance, which increases right ventricular afterload and
causes right heart failure (cor pulmonale). Systemic hypertension affects the left ventricle,
and left-to-right shunts cause volume overload, not pressure overload.
Q6.
A patient with type 1 diabetes mellitus accidentally administers an excessive dose of
insulin. Which of the following counter-regulatory hormones would be most important in
restoring euglycemia?
