,Q1. A patient with septic shock has a mean arterial pressure (MAP) of 58 mm Hg
despite fluid resuscitation. Norepinephrine is initiated. Which parameter best
indicates that the drug is achieving its therapeutic goal?
A. Urine output of 0.3 mL/kg/hr
B. Central venous pressure (CVP) of 12 mm Hg
C. Serum lactate level of 4 mmol/L
D. Systemic vascular resistance (SVR) of 900 dynes-sec/cm
Correct Answer: D. Systemic vascular resistance (SVR) of 900 dynes-sec/cm
Rationale: Norepinephrine is a potent vasoconstrictor; its primary goal in septic shock is
to restore vascular tone and improve perfusion. An SVR within normal range (800-1200
dynes-sec/cm) indicates effective vasoconstriction. Other options reflect inadequate
perfusion or volume status, not direct drug effect.
Why Wrong:
A - Low urine output indicates persistent renal hypoperfusion, not achievement of
vasopressor goal.
B - CVP reflects preload, not the vasopressor effect of norepinephrine.
C - Elevated lactate indicates ongoing tissue hypoxia, not therapeutic success.

Q2. In a patient with hyperkalemia, which electrocardiographic change is most
indicative of impending cardiac arrest?
A. Peaked T waves
B. Widened QRS complex
C. Prolonged PR interval
D. ST-segment depression
Correct Answer: B. Widened QRS complex
Rationale: As hyperkalemia worsens, the QRS complex widens due to slowed ventricular
conduction, which can deteriorate into ventricular fibrillation or asystole. Peaked T waves
and prolonged PR occur earlier; ST depression is less specific and not indicative of
imminent arrest.
Why Wrong:
A - Peaked T waves are an early sign but do not indicate imminent arrest.
C - Prolonged PR is an early conduction delay, not the most dangerous.
D - ST depression is not a hallmark of hyperkalemia.

, Q3. A patient with acute respiratory distress syndrome (ARDS) is on
volume-controlled ventilation with plateau pressure 28 cm HO and PaO/FiO ratio of
120. Which intervention is most appropriate to improve oxygenation while
minimizing further lung injury?
A. Increase tidal volume to 8 mL/kg ideal body weight
B. Increase positive end-expiratory pressure (PEEP)
C. Increase FiO to 100%
D. Switch to pressure-controlled ventilation
Correct Answer: B. Increase positive end-expiratory pressure (PEEP)
Rationale: In ARDS, increasing PEEP recruits collapsed alveoli, improving oxygenation
and reducing atelectrauma. Tidal volume should be low (6 mL/kg) to prevent volutrauma;
FiO may be increased but risks oxygen toxicity; pressure-controlled mode does not
inherently improve oxygenation.
Why Wrong:
A - Higher tidal volumes worsen lung injury in ARDS.
C - 100% FiO increases oxygen toxicity without addressing the underlying shunt.
D - Mode change alone does not improve oxygenation without optimizing PEEP.

Ch. 12.
Q4. Which of the following findings is most consistent with syndrome of
inappropriate antidiuretic hormone (SIADH) rather than diabetes insipidus (DI)?
A. Serum sodium 132 mEq/L, urine osmolality 600 mOsm/kg
B. Serum sodium 150 mEq/L, urine osmolality 100 mOsm/kg
C. Serum sodium 145 mEq/L, urine specific gravity 1.005
D. Serum sodium 128 mEq/L, urine specific gravity 1.001
Correct Answer: A. Serum sodium 132 mEq/L, urine osmolality 600 mOsm/kg
Rationale: SIADH is characterized by hyponatremia with concentrated urine (high urine
osmolality) due to excessive ADH. DI presents with hypernatremia and dilute urine.
Option A shows hyponatremia and high urine osmolality, classic for SIADH.
Why Wrong:
B - Hypernatremia with dilute urine is classic for DI.
C - Normal sodium with low specific gravity is not typical of either.
D - Low specific gravity suggests DI, not SIADH.

Q5. A patient with cirrhosis develops ascites and jaundice. Which laboratory finding
indicates the patient is at highest risk for spontaneous bacterial peritonitis (SBP)?
