NRNP 6566 Advanced Care of Adults in Acute Settings I Final Comprehensive Examination 2026/2027 | Verified Questions
,INTRODUCTION
This Final Comprehensive Examination contains exactly 100 original verified questions designed to
reinforce the official Walden University NRNP 6566 Advanced Care of Adults in Acute Settings I course
objectives for actual exam readiness and clinical proficiency, aligned to the 2026/2027 academic year.
The questions are organized across four core domains: Domain 1 – Acute Respiratory and Pulmonary
Disorders (25 questions); Domain 2 – Cardiovascular Emergencies and Hemodynamics (25 questions);
Domain 3 – Neurological Critical Care and Trauma (25 questions); and Domain 4 – Gastrointestinal,
Renal, and Endocrine Acute Care (25 questions). Each question is accompanied by the correct answer and
a detailed rationale grounded in foundational acute and critical care nursing methodology, including
principles drawn from university-level advanced nursing curricula and established textbooks such as
Urden’s Critical Care Nursing and Burns’ AACN Essentials of Critical Care Nursing. The content
emphasizes rapid recognition, differential diagnosis, and evidence-based acute interventions for life-
threatening conditions.
ACTUAL QUESTIONS
Domain 1: Acute Respiratory and Pulmonary Disorders
Question 1. A client with acute respiratory distress syndrome (ARDS) is receiving
mechanical ventilation. Which ventilator strategy is most consistent with lung-protective
ventilation?
A. Low tidal volume (approximately 6 mL/kg predicted body weight) with plateau pressure limited to
≤30 cm H2O
B. High tidal volumes of 12–15 mL/kg to normalize PaCO2
C. Zero positive end-expiratory pressure (PEEP)
D. Permissive hyperoxia with FiO2 1.0 continuously
Correct Answer: A
Rationale: Lung-protective ventilation using low tidal volumes and limited plateau pressures reduces
ventilator-induced lung injury and has been shown to improve survival in ARDS.
Question 2. Which arterial blood gas finding is most consistent with acute hypercapnic
respiratory failure?
A. PaO2 >100 mm Hg on room air
B. Normal PaCO2 with elevated bicarbonate
C. PaCO2 >50 mm Hg with pH <7.35
D. PaO2 90 mm Hg with pH 7.45
Correct Answer: C
Rationale: Hypercapnic (ventilatory) failure is defined by elevated PaCO2 and resulting respiratory
acidosis. Hypoxemic failure is defined by low PaO2.
Question 3. A client with severe community-acquired pneumonia develops progressive
hypoxemia. The PaO2/FiO2 ratio is 140. This value is consistent with:
A. Moderate ARDS (PaO2/FiO2 100–200)
B. Mild ARDS only
C. Severe ARDS exclusively
D. Normal gas exchange
Correct Answer: A
Rationale: The Berlin definition classifies ARDS severity by PaO2/FiO2 ratio: mild 200–300, moderate
100–200, severe <100, all with PEEP ≥5 cm H2O.

, Question 4. Which intervention is first-line for a spontaneously breathing client with acute
cardiogenic pulmonary edema and severe respiratory distress?
A. Immediate endotracheal intubation in all cases
B. Noninvasive positive-pressure ventilation (CPAP or BiPAP) if no contraindications exist
C. High-flow nasal cannula only without positive pressure
D. Avoidance of any oxygen therapy
Correct Answer: B
Rationale: Noninvasive ventilation reduces work of breathing, improves oxygenation, and can prevent
intubation in cardiogenic pulmonary edema when applied early.
Question 5. The primary pathophysiologic mechanism of shunting in ARDS is:
A. Pure diffusion limitation across a thickened membrane only
B. Dead-space ventilation exclusively
C. Alveolar flooding and collapse leading to perfusion of non-ventilated lung units
D. Upper-airway obstruction
Correct Answer: C
Rationale: Intrapulmonary shunting occurs when blood passes through unventilated alveoli, a hallmark
of ARDS that explains refractory hypoxemia.
Question 6. A client with COPD exacerbation is receiving BiPAP. Which finding indicates
the need to consider intubation?
A. Worsening mental status, rising PaCO2, or inability to protect the airway
B. Mild improvement in pH
C. Stable respiratory rate of 22
D. Ability to tolerate the mask
Correct Answer: A
Rationale: Failure of noninvasive ventilation is signaled by clinical deterioration, persistent or
worsening hypercapnia/acidosis, or loss of airway protective reflexes.
Question 7. Which oxygen delivery device can provide the highest FiO2 to a spontaneously
breathing client?
A. Nasal cannula at 2 L/min
B. Simple face mask at 5 L/min
C. Venturi mask at 24%
D. Non-rebreather mask with tight seal and adequate flow
Correct Answer: D
Rationale: A well-fitted non-rebreather mask with reservoir and high flow can deliver FiO2
approaching 0.90–1.0, higher than low-flow or fixed-performance devices.
Question 8. In a client with suspected pulmonary embolism, which diagnostic test is most
appropriate when CT pulmonary angiography is contraindicated by renal failure?
A. Immediate surgical embolectomy without imaging
B. Only D-dimer without further testing
C. Ventilation–perfusion (V/Q) scintigraphy
D. Chest radiograph alone
Correct Answer: C
Rationale: V/Q scanning remains useful when CTPA is contraindicated. A normal scan effectively
excludes PE; high-probability scans support the diagnosis in the appropriate clinical context.
