,Q1. A patient with septic shock has a cardiac index of 2.1 L/min/m², SVRI of 800 dynes-s-cm-m²,
and ScvO of 55%. Which intervention is most appropriate based on these findings?
A. Initiate norepinephrine to increase SVRI
B. Administer dobutamine to improve cardiac output
C. Transfuse packed red blood cells to increase oxygen content
D. Start vasopressin as a second vasopressor
Correct Answer: B. Administer dobutamine to improve cardiac output
Rationale: The low cardiac index and ScvO ‚ indicate inadequate oxygen delivery despite low SVRI
(vasodilation). Dobutamine increases cardiac output, improving oxygen delivery. Norepinephrine would
worsen already low cardiac output by increasing afterload. Transfusion may help but does not address
the primary deficit in contractility. Vasopressin is not first-line for cardiac output.
Why Wrong:
A - Increasing afterload with norepinephrine would further depress cardiac output in a patient with
low CI.
C - Transfusion increases oxygen content but does not address the low cardiac output driving the
ScvO decrease.
D - Vasopressin is used for refractory vasodilation, not for low cardiac output.

Q2. Which of the following acid-base disturbances is most consistent with a primary metabolic
alkalosis and appropriate respiratory compensation?
A. pH 7.48, PaCO 30 mm Hg, HCO 24 mEq/L
B. pH 7.46, PaCO 47 mm Hg, HCO 32 mEq/L
C. pH 7.38, PaCO 40 mm Hg, HCO 24 mEq/L
D. pH 7.50, PaCO 50 mm Hg, HCO 36 mEq/L
Correct Answer: B. pH 7.46, PaCO 47 mm Hg, HCO 32 mEq/L
Rationale: Metabolic alkalosis is indicated by elevated HCO ƒ { and pH. Appropriate compensation is
hypoventilation (increased PaCO) to raise PaCO by 0.7 x HCO (Winter's-like rule). Here HCO = 8,
predicted PaCO = 40 + 0.7*8 = 45.6, close to 47. Option D has excessive PaCO indicating additional
respiratory acidosis.
Why Wrong:
A - Low PaCO indicates respiratory alkalosis, not compensation for metabolic alkalosis.
C - All values are normal, no alkalosis.
D - PaCO of 50 exceeds expected compensation, suggesting superimposed respiratory acidosis.

, Q3. In a patient with cardiogenic shock, which vasoactive agent is most likely to increase myocardial
oxygen demand the least?
A. Dobutamine
B. Milrinone
C. Epinephrine
D. Norepinephrine
Correct Answer: B. Milrinone
Rationale: Milrinone, a phosphodiesterase-3 inhibitor, increases contractility and vasodilation without
significantly increasing heart rate or afterload, thus minimally increasing myocardial oxygen demand.
Dobutamine increases heart rate and contractility, raising demand. Epinephrine and norepinephrine are
potent inotropes/vasopressors that markedly increase oxygen consumption.
Why Wrong:
A - Dobutamine increases heart rate and contractility, raising myocardial oxygen demand.
C - Epinephrine is a strong inotrope and chronotrope, greatly increasing oxygen demand.
D - Norepinephrine increases afterload and contractility, increasing oxygen demand.

Q4. A patient with obstructive shock from massive pulmonary embolism has a PaO of 65 mm Hg on
100% FiO. Which of the following best explains the hypoxemia?
A. Increased intrapulmonary shunting due to atelectasis
B. Ventilation-perfusion mismatch from decreased cardiac output
C. Diffusion impairment due to pulmonary edema
D. Hypoventilation secondary to increased dead space
Correct Answer: B. Ventilation-perfusion mismatch from decreased cardiac output
Rationale: In massive PE, decreased cardiac output reduces mixed venous oxygen content, and areas of
low V/Q worsen hypoxemia. The high FiO response suggests shunt is not the primary cause. Diffusion
impairment is not typical for acute PE. Hypoventilation may occur but is not the main cause.
Why Wrong:
A - Shunt would not improve with 100% FiO; PaO would remain low.
C - Diffusion impairment is not a typical mechanism in acute PE.
D - Hypoventilation would cause hypercapnia, not isolated hypoxemia.
