,Q1. During maximal exercise, cardiac output increases fourfold. Which integrative
adjustment most accurately describes the concurrent changes in mean arterial
pressure (MAP) and total peripheral resistance (TPR)?
A. MAP rises markedly due to increased TPR from sympathetic vasoconstriction in
active muscle.
B. MAP increases modestly because TPR falls despite a large rise in cardiac output.
C. MAP remains unchanged because TPR increases proportionally with cardiac output.
D. MAP falls while TPR increases, reflecting the dominance of metabolic vasodilation.
Correct Answer: B. MAP increases modestly because TPR falls despite a large rise in
cardiac output.
Rationale: During exercise, cardiac output rises substantially, but active skeletal muscle
vasodilation reduces TPR, so MAP increases only modestly. Option A incorrectly
attributes the rise to TPR. Option C is wrong because TPR does not increase
proportionally; it typically decreases. Option D is incorrect because MAP does not fall, it
rises modestly.
Why Wrong:
A - Exercise causes vasodilation in active muscle, reducing TPR, not increasing it.
C - TPR decreases, not increases, during exercise due to metabolic vasodilation.
D - MAP rises modestly, not falls, because the increase in cardiac output outweighs
the decrease in TPR.

Q2. A drug selectively blocks the sodium-glucose cotransporter 2 (SGLT2) in the
proximal tubule. Which combination of renal effects is most expected?
A. Increased glucosuria, increased osmotic diuresis, and increased urinary calcium
excretion.
B. Decreased glucosuria, decreased osmotic diuresis, and decreased urinary calcium
excretion.
C. Increased glucosuria, decreased osmotic diuresis, and increased urinary sodium
excretion.
D. Increased glucosuria, increased osmotic diuresis, and decreased urinary phosphate
excretion.
Correct Answer: A. Increased glucosuria, increased osmotic diuresis, and increased
urinary calcium excretion.
Rationale: SGLT2 inhibition reduces glucose reabsorption, leading to glucosuria and
osmotic diuresis. The osmotic diuresis also enhances calcium excretion because sodium
and water reabsorption in the proximal tubule is coupled to calcium reabsorption. Option
B is opposite. Option C is wrong because osmotic diuresis is increased, not decreased.
Option D is incorrect because phosphate excretion is not directly increased by SGLT2

, inhibition.
Why Wrong:
B - SGLT2 blockade increases, not decreases, glucosuria and osmotic diuresis.
C - Osmotic diuresis is increased, not decreased, with SGLT2 inhibition.
D - SGLT2 inhibition does not directly increase phosphate excretion; calcium
excretion is increased.

Q3. A researcher measures airway resistance before and after administering a drug
that blocks M3 muscarinic receptors. Which pulmonary effect is most consistent with
this drug?
A. Decreased bronchoconstriction and increased dead space ventilation.
B. Increased bronchoconstriction and decreased alveolar ventilation.
C. Decreased bronchoconstriction and increased alveolar ventilation.
D. Increased bronchoconstriction and increased physiological dead space.
Correct Answer: C. Decreased bronchoconstriction and increased alveolar
ventilation.
Rationale: Blocking M3 receptors on bronchial smooth muscle inhibits cholinergic
bronchoconstriction, leading to bronchodilation and decreased airway resistance. This
improves alveolar ventilation. Option A is wrong because dead space ventilation is not
directly increased. Option B is opposite. Option D is incorrect because the drug is
bronchodilatory, not bronchoconstrictive.
Why Wrong:
A - Bronchodilation does not increase dead space; it improves ventilation-perfusion
matching.
B - M3 blockade causes bronchodilation, not bronchoconstriction.
D - M3 blockade decreases airway resistance, so bronchoconstriction is not increased.

Q4. A patient has a pH of 7.50, PaCO2 of 48 mm Hg, and [HCO3-] of 36 mEq/L.
Which compensatory response is most likely occurring?
A. Renal excretion of bicarbonate and retention of hydrogen ions.
B. Renal retention of bicarbonate and excretion of hydrogen ions.
C. Pulmonary hypoventilation to retain CO2.
D. Pulmonary hyperventilation to blow off CO2.
Correct Answer: A. Renal excretion of bicarbonate and retention of hydrogen ions.
Rationale: The pH is alkalotic, with elevated HCO3- and PaCO2, indicating metabolic
alkalosis with respiratory compensation (hypoventilation). The renal compensatory
response to metabolic alkalosis is to excrete bicarbonate and retain hydrogen ions, which
