AND
QUALIFIED ANSWERS
100% CORRECT
1.

,A patient in septic shock has a MAP of 58 mmHg despite
fluid resuscitation. Which medication should the nurse
anticipate?
A. Dopamine
B. Dobutamine
C. Norepinephrine
D. Epinephrine
Answer: C. Norepinephrine
Rationale: Norepinephrine is the first-line vasopressor for
septic shock to increase MAP ≥65 mmHg.


2.
Which parameter best indicates adequate tissue
perfusion?
A. BP
B. Urine output
C. Heart rate
D. CVP
Answer: B. Urine output
Rationale: Urine output ≥0.5 mL/kg/hr reflects adequate
renal perfusion.

,3.
A patient with ARDS is on mechanical ventilation. Which
setting helps prevent alveolar collapse?
A. Tidal volume
B. PEEP
C. FiO2
D. Rate
Answer: B. PEEP
Rationale: Positive end-expiratory pressure prevents
alveolar collapse and improves oxygenation.


4.
Which ABG indicates respiratory acidosis?
A. pH 7.25, PaCO₂ 55
B. pH 7.45, PaCO₂ 30
C. pH 7.50, HCO₃ 30
D. pH 7.35, HCO₃ 18
Answer: A. pH 7.25, PaCO₂ 55
Rationale: Low pH and high CO₂ indicate respiratory
acidosis.

, 5.
A patient develops ventricular tachycardia with a pulse.
First action?
A. Defibrillation
B. Amiodarone
C. CPR
D. Epinephrine
Answer: B. Amiodarone
Rationale: Stable VT with a pulse is treated with
antiarrhythmics.


6.
Which sign indicates worsening intracranial pressure?
A. Hypotension
B. Bradycardia
