Q1.
In a patient with chronic heart failure, which compensatory mechanism initially maintains
cardiac output but ultimately leads to detrimental ventricular remodeling and increased
myocardial oxygen demand?
A. Enhanced renal sodium and water B. Activation of the
excretion via natriuretic peptides renin-angiotensin-aldosterone system and
sympathetic nervous system
C. Downregulation of beta-adrenergic D. Increased production of atrial natriuretic
receptors on cardiac myocytes peptide from atrial stretch
Correct: B - Activation of the renin-angiotensin-aldosterone system and sympathetic
nervous system
Rationale:Chronic heart failure triggers RAAS and sympathetic activation, which initially
support cardiac output via increased contractility and fluid retention, but chronic activation
leads to remodeling, fibrosis, and increased oxygen demand. Natriuretic peptides are
counter-regulatory, not primary compensatory. Beta-receptor downregulation is a
consequence, not a compensatory mechanism.
Q2.
A blood sample shows a pH of 7.25, PaCO2 of 60 mm Hg, and HCO3- of 26 mEq/L. What is
the primary acid-base disturbance and the expected renal compensation?
A. Metabolic acidosis with renal retention of B. Respiratory acidosis with renal retention
bicarbonate of bicarbonate
C. Respiratory alkalosis with renal excretion D. Metabolic alkalosis with renal excretion of
of bicarbonate bicarbonate
Correct: B - Respiratory acidosis with renal retention of bicarbonate
Rationale:Low pH and high PaCO2 indicate respiratory acidosis. The kidneys compensate by
retaining bicarbonate (increasing HCO3-), which is partially evident here. Metabolic acidosis
would show low HCO3-; respiratory alkalosis would show low PaCO2; metabolic alkalosis
would show high HCO3- and pH.

Q3.
Which of the following best explains the phenomenon of 'glomerulotubular balance'?
A. The renal tubules reabsorb a constant B. Tubular reabsorption of sodium increases
fraction of filtered sodium regardless of GFR proportionally with increases in GFR
C. Glomerular filtration rate is regulated by D. Peritubular capillary hydrostatic pressure
tubular flow via tubuloglomerular feedback adjusts to maintain constant GFR
Correct: B - Tubular reabsorption of sodium increases proportionally with increases in
GFR
Rationale:Glomerulotubular balance refers to the intrinsic ability of the proximal tubule to
reabsorb a constant fraction (about 65-70%) of filtered sodium and water, so reabsorption
increases with GFR. It does not involve tubuloglomerular feedback (which regulates GFR) or
peritubular capillary dynamics.
Q4.
Which of the following accurately describes the oxygen-hemoglobin dissociation curve
shift caused by increased 2,3-BPG?
A. Left shift, increased affinity, decreased B. Right shift, decreased affinity, increased
P50 P50
C. Left shift, decreased affinity, increased D. Right shift, increased affinity, decreased
P50 P50
Correct: B - Right shift, decreased affinity, increased P50
Rationale:Increased 2,3-BPG stabilizes the deoxygenated (T) state of hemoglobin, reducing
oxygen affinity and causing a rightward shift of the curve, with an increased P50 (the partial
pressure at which hemoglobin is 50% saturated). This facilitates oxygen unloading to tissues.
Q5.
A patient has a pulmonary embolism. Which ventilation-perfusion (V/Q) mismatch pattern
is expected, and what is the immediate compensatory vasomotor response?
A. V/Q ratio approaches zero; hypoxic B. V/Q ratio approaches infinity; pulmonary
pulmonary vasoconstriction in affected vasodilation in affected region
region
C. V/Q ratio approaches zero; pulmonary D. V/Q ratio approaches infinity; hypoxic
vasodilation in affected region pulmonary vasoconstriction in unaffected
regions
Correct: A - V/Q ratio approaches zero; hypoxic pulmonary vasoconstriction in affected
region
