ANCC AGACNP ADVANCED BOARD REVIEW
PRACTICE EXAM 2026 QUESTIONS AND
ANSWERS WITH DETAILED RATIONALES
This comprehensive question practice bank is directly
engineered to match the official ANCC Adult-Gerontology
Acute Care Nurse Practitioner (AGACNP-BC®) test content
outline blueprint. Every high-yield, board-style question is
immediately accompanied by its verified correct answer and
a detailed, evidence-based rationale to bridge critical clinical
and policy knowledge gaps. It is the ultimate premium study
tool for students and clinicians looking to secure a passing
score on the first attempt.
Question 1
A 65-year-old male with an acute exacerbation of chronic
obstructive pulmonary disease (COPD) is admitted to the
progressive care unit. Arterial blood gas (ABG) on 2L nasal
cannula reveals: pH 7.28, PaCO2 62 mmHg, PaO2 54 mmHg,
HCO3 28 mEq/L. The patient is awake, alert, and able to protect
his airway but is using accessory muscles to breathe. Which of
the following is the most appropriate initial respiratory
intervention?
A) Increase the nasal cannula to 6L/min
B) Initiate non-invasive positive pressure ventilation (BiPAP)
C) Orally intubate and initiate mechanical ventilation
,D) Administer intravenous continuous infusion of midazolam
Answer: B
Rationale: This patient is experiencing acute-on-chronic
respiratory acidosis with hypoxemia (Type 5/mixed
exacerbation profile). Because he is alert and able to protect
his airway, non-invasive positive pressure ventilation (BiPAP)
is the first-line gold standard intervention. BiPAP decreases
the work of breathing, improves alveolar ventilation, lowers
PaCO2, and helps avoid the complications of invasive
mechanical ventilation. Increasing nasal cannula will not fix
the hypoventilation/hypercapnia, while intubation is
premature.
Question 2
A 44-year-old female is admitted to the intensive care unit with a
severe case of acute pancreatitis. On hospital day 2, she
develops sudden, progressive dyspnea and anxiety. Her
respiratory rate is 32 breaths per minute, and her oxygen
saturation drops to 84% on a non-rebreather mask. Chest X-ray
demonstrates diffuse, bilateral alveolar infiltrates without
cardiomegaly or pleural effusions. Her PaO2/FiO2 (P/F) ratio is
calculated to be 140. Which of the following pathophysiological
mechanisms explains her current respiratory status?
A) Increased hydrostatic capillary pressure leading to transudative
fluid movement
B) Decreased oncotic vascular pressure from acute systemic
protein wasting
C) Endothelial damage and increased alveolar-capillary
permeability
D) Cardiogenic pulmonary congestion caused by acute
,myocardial stunning
Answer: C
Rationale: The clinical picture describes Acute Respiratory
Distress Syndrome (ARDS) secondary to severe acute
pancreatitis (an intra-abdominal inflammatory trigger). The
underlying pathophysiology of ARDS involves a profound
systemic inflammatory response that causes endothelial
injury, leading to increased alveolar-capillary permeability.
This allows protein-rich exudative fluid to flood the alveoli,
causing severe shunting and hypoxemia. This is non-
cardiogenic pulmonary edema, which rules out hydrostatic
pressure changes or primary oncotic pressure shifts.
Question 3
While managing a 72-year-old patient with an arterial line in the
intensive care unit, the AGACNP notes that the arterial waveform
has become significantly overdampened. The monitor shows an
artificially low systolic blood pressure and an artificially high
diastolic blood pressure. Which of the following troubleshooting
maneuvers is most appropriate?
A) Reposition the transducer so it sits 5 cm above the
phlebostatic axis
B) Check the tubing system for air bubbles, blood clots, or
excessive compliant kinks
C) Flush the line vigorously with a 10 mL syringe filled with sterile
water
D) Replace the indwelling arterial catheter immediately over a
guidewire
Answer: B
Rationale: An overdampened arterial waveform is
, characterized by a slurred upstroke, loss of the dicrotic
notch, and compressed pulse pressures (falsely low
systolic/falsely high diastolic). Common physical causes
include air bubbles within the transducer fluid columns,
blood clots at the catheter tip, or overly compliant/long
extensions and kinks. Adjusting the transducer height fixes
atmospheric pressure calibration discrepancies, not
dampening coefficients. Flushes should be performed with
the built-in flush device using saline, never a manual water
flush which introduces hemolysis and contamination risks.
Question 4
A 55-year-old male is undergoing hemodynamic monitoring via a
pulmonary artery (Swan-Ganz) catheter. The nurse reports the
following values: Central Venous Pressure (CVP) 2 mmHg,
Pulmonary Capillary Wedge Pressure (PCWP) 4 mmHg, Cardiac
Index (CI) 1.8 L/min/m², and Systemic Vascular Resistance (SVR)
1,650 dynes/sec/cm⁻⁵. Which clinical shock state matches this
physiological profile?
A) Cardiogenic shock
B) Hypovolemic shock
C) Neurogenic shock
D) Septic shock
Answer: B
Rationale: Hypovolemic shock is characterized by low
volume indicators—low CVP (preload of the right heart) and
low PCWP (preload of the left heart). Because of decreased
venous return, cardiac output/index drops. The body
compensates for low cardiac output through sympathetic
nervous system activation, causing profound peripheral
