,Q1. A client with severe sepsis develops acute respiratory distress syndrome (ARDS).
Which ventilator strategy is most appropriate to minimize further lung injury?
A. High tidal volume (10-12 mL/kg) with low PEEP
B. Low tidal volume (6 mL/kg ideal body weight) with plateau pressure 30 cm H2O
C. Pressure-controlled ventilation with high FiO2 and no PEEP
D. Volume-controlled ventilation with tidal volume 8 mL/kg and zero PEEP
Correct Answer: B. Low tidal volume (6 mL/kg ideal body weight) with plateau
pressure 30 cm H2O
Rationale: Low tidal volume ventilation (6 mL/kg) and limiting plateau pressure to "d30 cm
H2O is the evidence-based strategy for ARDS to prevent ventilator-induced lung injury.
High tidal volumes and inadequate PEEP worsen lung damage.
Why Wrong:
A - High tidal volume causes volutrauma and exacerbates ARDS.
C - High FiO2 and no PEEP fail to recruit alveoli and promote atelectasis.
D - Zero PEEP allows alveolar collapse and decreases functional residual capacity.

Ed., Ch. 12
Q2. Which pharmacodynamic principle best explains why a drug with a high
therapeutic index is generally safer than one with a low therapeutic index?
A. It has a shorter half-life, reducing accumulation.
B. The margin between the effective dose and the lethal dose is wide.
C. It is less protein-bound, increasing free drug concentration.
D. It has a steeper dose-response curve, allowing precise titration.
Correct Answer: B. The margin between the effective dose and the lethal dose is wide.
Rationale: The therapeutic index is the ratio of the median lethal dose (LD50) to the
median effective dose (ED50). A high therapeutic index indicates a wide margin of safety
between therapeutic and toxic effects.
Why Wrong:
A - Half-life affects dosing interval, not safety margin.
C - Protein binding affects distribution, not the safety margin.
D - A steeper curve increases toxicity risk, reducing safety.
Reference: Lehne, R.A., & Rosenthal, L. (2026). Pharmacology for Nursing Care, 11th
Ed., Ch. 4
Q3. A nurse is reviewing a client's arterial blood gas results: pH 7.48, PaCO2 32 mm
Hg, HCO3- 24 mEq/L. Which condition is most consistent with these findings?
A. Metabolic acidosis
Page 3
, B. Respiratory alkalosis
C. Metabolic alkalosis
D. Respiratory acidosis
Correct Answer: B. Respiratory alkalosis
Rationale: Elevated pH (alkalosis) with decreased PaCO2 indicates primary respiratory
alkalosis. The HCO3- is normal, ruling out metabolic compensation. This pattern occurs
with hyperventilation.
Why Wrong:
A - Metabolic acidosis would show low pH and low HCO3-.
C - Metabolic alkalosis would show high pH and high HCO3-.
D - Respiratory acidosis would show low pH and high PaCO2.
Reference: Fischbach, F.T., & Dunning, M.B. (2026). A Manual of Laboratory and
Diagnostic Tests, 11th Ed., Ch. 3
Q4. In a patient with hyperkalemia, which electrocardiographic change is most
indicative of impending cardiac arrest?
A. Peaked T waves
B. Prolonged PR interval
C. Sine wave pattern
D. Widened QRS complex
Correct Answer: C. Sine wave pattern
Rationale: A sine wave pattern represents severe hyperkalemia with loss of P waves and
merging of QRS and T waves, indicating imminent cardiac arrest. Peaked T waves and
widened QRS occur earlier but are not as immediately life-threatening.
Why Wrong:
A - Peaked T waves are an early sign but not the most critical.
B - Prolonged PR interval is a progression sign but not the terminal pattern.
D - Widened QRS is serious but precedes the sine wave pattern.
Reference: Ignatavicius, D.D., Workman, M.L., et al. (2026). Medical-Surgical Nursing,
10th Ed., Ch. 17
Q5. A nurse is evaluating a client's understanding of a low-glycemic index diet. Which
food choice indicates a need for further teaching?
A. Steel-cut oats
B. White rice
C. Lentils
D. Quinoa
Correct Answer: B. White rice
