Introduction
This comprehensive examination is designed to assess the progressive care nurse's clinical reasoning, evidence-
based practice, and critical decision-making skills across the full spectrum of acutely ill adult patient populations.
The exam integrates foundational pathophysiological concepts with applied professional knowledge, regulatory
compliance, and ethical standards. Each question presents a clinical scenario or theoretical construct requiring the
application of nursing judgment, prioritization, and intervention selection. The multiple-choice format mirrors the
structure of the actual certification examination, emphasizing real-world application and the ability to synthesize
,complex clinical data to optimize patient outcomes. Candidates are expected to demonstrate proficiency in
hemodynamic monitoring, pharmacological management, and interdisciplinary collaboration in progressive care
settings.
SECTION ONE: QUESTIONS 1–100
Question 1
A 68-year-old patient with a history of hypertension and type 2 diabetes is admitted with acute decompensated
heart failure. The patient's vital signs are: BP 158/92 mmHg, HR 102 bpm, RR 24/min, SpO2 91% on 4 L nasal
cannula. Jugular venous distension is noted at 12 cm H2O, and bilateral crackles are auscultated to the mid-
scapular region. Which initial intervention is most appropriate?
A. Administer intravenous furosemide 40 mg push
B. Initiate continuous positive airway pressure (CPAP) at 10 cm H2O
C. Administer intravenous morphine sulfate 2 mg
D. Place the patient in a high-Fowler's position and apply supplemental oxygen
🟢D
,🔴 RATIONALE: High-Fowler's positioning optimizes ventilation-perfusion matching by reducing venous return
and decreasing preload, which alleviates pulmonary congestion. While furosemide, CPAP, and morphine are all
appropriate interventions, positioning and oxygenation are the immediate first-line actions to stabilize the
patient and improve oxygenation before further pharmacologic or ventilatory support is initiated. This
prioritization reflects the ABC (airway, breathing, circulation) framework in acute decompensated heart failure.
Question 2
Which laboratory finding is most consistent with a diagnosis of syndrome of inappropriate antidiuretic hormone
(SIADH)?
A. Serum sodium 118 mEq/L, serum osmolality 260 mOsm/kg, urine osmolality 600 mOsm/kg
B. Serum sodium 152 mEq/L, serum osmolality 310 mOsm/kg, urine osmolality 150 mOsm/kg
C. Serum sodium 135 mEq/L, serum osmolality 285 mOsm/kg, urine osmolality 400 mOsm/kg
D. Serum sodium 145 mEq/L, serum osmolality 295 mOsm/kg, urine osmolality 800 mOsm/kg
🟢A
🔴 RATIONALE: SIADH is characterized by dilutional hyponatremia (serum sodium <135 mEq/L), low serum
osmolality (<275 mOsm/kg), and inappropriately concentrated urine (urine osmolality >100 mOsm/kg) due to
excessive antidiuretic hormone secretion. Option A demonstrates classic SIADH findings, while option B reflects
, hypernatremia and hyperosmolality consistent with diabetes insipidus. Options C and D represent normal or
equivocal findings.
Question 3
A patient in the progressive care unit is receiving continuous telemetry monitoring. The rhythm strip reveals a
regular rhythm with a rate of 42 bpm, absent P waves, and wide QRS complexes (>0.12 seconds). The patient is
asymptomatic with a BP of 128/74 mmHg. Which of the following is the most appropriate initial management?
A. Transcutaneous pacing
B. Atropine 0.5 mg intravenous push
C. Dopamine infusion at 5 mcg/kg/min
D. Observation with continued monitoring
🟢D
🔴 RATIONALE: This rhythm is consistent with a slow idioventricular rhythm. In the absence of hemodynamic
instability (hypotension, altered mental status, ischemic chest pain, or signs of shock), asymptomatic
bradyarrhythmias do not require immediate intervention. Observation and continued monitoring are
appropriate while identifying and treating the underlying cause. Atropine, pacing, and dopamine are reserved
for symptomatic bradycardia or hemodynamically significant rhythms.
