,Q1. A patient with chronic kidney disease has a serum potassium of 6.2 mEq/L.
Which electrocardiographic change is most likely to be observed, and what is the
immediate underlying ionic mechanism?
A. Peaked T waves due to accelerated phase 3 repolarization
B. Prolonged PR interval due to slowed atrial conduction
C. Widened QRS complex due to delayed ventricular depolarization
D. Absent P waves due to suppressed sinoatrial node automaticity
Correct Answer: A. Peaked T waves due to accelerated phase 3 repolarization
Rationale: Hyperkalemia primarily affects cardiac myocyte repolarization, leading to
accelerated phase 3 repolarization and characteristic peaked T waves. While severe
hyperkalemia can cause widened QRS and loss of P waves, these are later manifestations.
The earliest and most specific ECG change is peaked T waves.
Why Wrong:
B - Prolonged PR interval is more associated with first-degree AV block, not directly
with hyperkalemia's early effects.
C - Widened QRS occurs in severe hyperkalemia but is a later sign, not the initial
manifestation.
D - Absent P waves occur in extreme hyperkalemia, but peaked T waves appear
earlier.

in Adults and Children, 9th ed., Ch. 5
Q2. A patient develops metabolic alkalosis due to prolonged vomiting. Which
compensatory mechanism would the body employ, and what is the expected direction
of change in arterial blood gas values?
A. Hypoventilation leading to increased PaCO2
B. Hyperventilation leading to decreased PaCO2
C. Increased renal excretion of bicarbonate
D. Increased renal reabsorption of hydrogen ions
Correct Answer: A. Hypoventilation leading to increased PaCO2
Rationale: Metabolic alkalosis triggers respiratory compensation via hypoventilation to
retain CO2, thereby increasing PaCO2 and helping to normalize pH. Renal compensation
would involve increased bicarbonate excretion, but that is slower and not the immediate
respiratory response.
Why Wrong:
B - Hyperventilation and decreased PaCO2 would worsen alkalosis by lowering CO2,
which is acid.
C - Renal bicarbonate excretion is a renal compensation, but the question asks for the
immediate compensatory mechanism.
Page 3
, D - Increased renal reabsorption of hydrogen ions would worsen alkalosis; kidneys
would excrete more bicarbonate and conserve H+.

Q3. Which statement accurately contrasts the intrinsic and extrinsic pathways of the
coagulation cascade?
A. The intrinsic pathway is initiated by tissue factor (factor III) and is measured by PT.
B. The extrinsic pathway is initiated by exposure to collagen and is measured by aPTT.
C. Both pathways converge at the activation of factor X, and the common pathway
includes prothrombin to thrombin conversion.
D. The intrinsic pathway requires vitamin K-dependent factors II, VII, IX, and X,
whereas the extrinsic pathway does not.
Correct Answer: C. Both pathways converge at the activation of factor X, and the
common pathway includes prothrombin to thrombin conversion.
Rationale: The intrinsic and extrinsic pathways converge at factor X activation, leading to
the common pathway where prothrombin is converted to thrombin. This is a fundamental
concept in understanding coagulation and the effects of anticoagulants.
Why Wrong:
A - The intrinsic pathway is initiated by collagen exposure, not tissue factor, and is
measured by aPTT.
B - The extrinsic pathway is initiated by tissue factor (factor III) and is measured by
PT, not aPTT.
D - Both pathways rely on vitamin K-dependent factors; the extrinsic pathway
includes factor VII, which is vitamin K-dependent.

Q4. A patient is prescribed spironolactone, a potassium-sparing diuretic. Which
electrolyte imbalance is a potential adverse effect, and what is the mechanism?
A. Hyponatremia due to increased sodium excretion in the distal tubule
B. Hyperkalemia due to antagonism of aldosterone receptors in the collecting duct
C. Hypokalemia due to increased potassium secretion in the proximal tubule
D. Hypercalcemia due to increased calcium reabsorption in the thick ascending limb
Correct Answer: B. Hyperkalemia due to antagonism of aldosterone receptors in the
collecting duct
Rationale: Spironolactone blocks aldosterone receptors in the distal nephron, reducing
sodium reabsorption and potassium secretion, leading to potassium retention and
potential hyperkalemia. This is a key clinical consideration when using this medication.
Why Wrong:
A - Hyponatremia is not a common effect; spironolactone actually increases sodium
