,Q1 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
A patient with acute respiratory distress syndrome (ARDS) has a PaO2 of 58
mmHg despite an FiO2 of 0.8. Which intervention is most likely to improve
oxygenation while minimizing ventilator-induced lung injury?
A. Increase PEEP to recruit collapsed alveoli and reduce tidal volume to 6 mL/kg ideal body
weight. CORRECT
B. Increase tidal volume to 10 mL/kg to ensure adequate minute ventilation.
C. Switch to pressure-controlled ventilation with peak pressures limited to 20 cm H2O.
D. Decrease FiO2 to 0.5 to reduce oxygen toxicity.
RATIONALE: Evidence-based ARDS management uses low tidal volumes (4-8 mL/kg) and
adequate PEEP to improve oxygenation while preventing volutrauma. Increasing tidal volume
worsens lung injury; pressure-controlled ventilation does not guarantee low tidal volumes;
decreasing FiO2 without addressing the underlying shunt would worsen hypoxemia.
Q2 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
A patient on a continuous heparin infusion develops a sudden drop in platelet
count. Which antibody test confirms the diagnosis of heparin-induced
thrombocytopenia (HIT)?
A. Anti-platelet factor 4 (PF4)-heparin antibody ELISA CORRECT
B. Anti-cardiolipin antibody
C. Anti-neutrophil cytoplasmic antibody (ANCA)
D. Anti-glomerular basement membrane antibody
RATIONALE: HIT is caused by antibodies against PF4-heparin complexes, leading to platelet
activation and thrombosis. Anti-cardiolipin antibodies are associated with antiphospholipid
syndrome, ANCA with vasculitis, and anti-GBM with Goodpasture syndrome; none are specific
for HIT.

,Q3 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
A patient with chronic kidney disease (CKD) has a serum potassium of 6.2 mEq/L
and an ECG showing peaked T waves. Which medication acts by shifting
potassium into cells, providing the fastest onset of action?
A. Calcium gluconate
B. Insulin with dextrose CORRECT
C. Sodium polystyrene sulfonate
D. Furosemide
RATIONALE: Insulin with dextrose shifts potassium into cells within 15-30 minutes, rapidly
lowering serum potassium. Calcium gluconate stabilizes the myocardium but does not lower
potassium. Sodium polystyrene sulfonate and furosemide remove potassium from the body but
have a slower onset.
Q4 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
Which ethical principle is most directly violated when a nurse fails to obtain
informed consent before a procedure?
A. Autonomy CORRECT
B. Beneficence
C. Justice
D. Fidelity
RATIONALE: Informed consent respects the patient's right to self-determination, which is
autonomy. Beneficence involves acting in the patient's best interest, justice relates to fairness,
and fidelity is keeping promises. Failure to obtain consent undermines autonomy.

, Q5 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
A patient with a history of heart failure is taking a loop diuretic. Which laboratory
value is most critical to monitor to prevent a common adverse effect of this
medication?
A. Serum potassium CORRECT
B. Serum sodium
C. Serum creatinine
D. Serum calcium
RATIONALE: Loop diuretics cause hypokalemia, which can lead to arrhythmias, especially in
heart failure patients. Monitoring potassium is crucial. Sodium, creatinine, and calcium are also
affected, but hypokalemia is the most immediately life-threatening.
Q6 ANALYZE COMPLEX PATIENT DATA TO FORMULATE EVIDENCE-BASED NURSING
INTERVENTIONS
A patient with sepsis and hypotension has a serum lactate of 4 mmol/L. After a 30
mL/kg crystalloid bolus, the blood pressure remains 70/40 mmHg. What is the next
most appropriate intervention?
A. Initiate norepinephrine infusion CORRECT
B. Administer another 30 mL/kg fluid bolus
C. Start broad-spectrum antibiotics
D. Obtain blood cultures before antibiotics
RATIONALE: In septic shock, after initial fluid resuscitation, vasopressors (norepinephrine is
first-line) are indicated for persistent hypotension. Additional fluids may be given but
vasopressors are the priority. Antibiotics should be given early, but they do not immediately
correct hypotension. Blood cultures should not delay antibiotics.
