Introduction
This comprehensive post-test is designed to evaluate the advanced clinical knowledge, critical reasoning, and
decision-making skills of candidates preparing for the Barkley Adult-Gerontology Acute Care Nurse Practitioner
(AGACNP) certification examination. Building upon foundational concepts, this assessment challenges candidates
to integrate complex pathophysiological principles, interpret advanced hemodynamic and laboratory data, and
,apply evidence-based guidelines to manage critically ill adult and geriatric patients. The multiple-choice and
scenario-based questions emphasize real-world acute care application, rapid prioritization, and the synthesis of
knowledge necessary for safe, effective, and compassionate care in emergency and intensive care settings. This
post-test serves as a final readiness assessment to identify areas for focused review prior to the certification
examination.
SECTION ONE: QUESTIONS 1–100
1. A 72-year-old male is admitted to the ICU with septic shock secondary to pneumonia. He is intubated and
mechanically ventilated. He has received 30 mL/kg of crystalloid and is on norepinephrine at 0.5
mcg/kg/min. His mean arterial pressure (MAP) remains 58 mmHg, and his central venous pressure (CVP) is
14 mmHg. Which of the following is the most appropriate next step in hemodynamic management?
A. Increase the norepinephrine infusion rate.
B. Administer another fluid bolus.
C. Start vasopressin infusion.
D. Initiate dobutamine infusion.
🟢C
🔴 RATIONALE: The patient has persistent hypotension despite adequate fluid resuscitation (CVP 14 mmHg)
and moderate-dose norepinephrine. The Surviving Sepsis Campaign guidelines recommend adding vasopressin
,(0.03 units/min) as a second-line vasopressor in this scenario. Increasing norepinephrine is an option but
vasopressin is specifically recommended. Another fluid bolus is not indicated with a high CVP. Dobutamine is
used for low cardiac output.
2. A 68-year-old female is in the ICU following a motor vehicle accident. She is sedated and mechanically
ventilated. Which of the following is the most effective evidence-based strategy to reduce the risk of
ventilator-associated pneumonia (VAP)?
A. Routine administration of prophylactic antibiotics.
B. Elevating the head of the bed to 30-45 degrees.
C. Performing daily chest X-rays.
D. Using a supine position for patient comfort.
🟢B
🔴 RATIONALE: Elevating the head of the bed to 30-45 degrees is a core component of the VAP prevention
bundle and is strongly supported by evidence to reduce aspiration. Prophylactic antibiotics are not
recommended. Daily chest X-rays are not a preventive strategy. Supine positioning is a risk factor for VAP.
3. A 75-year-old male with a history of heart failure is admitted with acute respiratory failure. He is intubated
and placed on mechanical ventilation. His arterial blood gas (ABG) on volume-controlled ventilation is: pH
, 7.20, PaCO2 65 mmHg, PaO2 75 mmHg, HCO3 26 mEq/L. Which of the following ventilator adjustments is
most appropriate?
A. Increase the respiratory rate to 24 breaths/min.
B. Decrease the tidal volume to 6 mL/kg.
C. Increase the FiO2 to 0.8.
D. Decrease the PEEP to 5 cm H2O.
🟢A
🔴 RATIONALE: The ABG shows severe respiratory acidosis (pH 7.20, PaCO2 65) with a normal bicarbonate,
indicating an acute process. The most appropriate adjustment is to increase the minute ventilation by increasing
the respiratory rate to lower the PaCO2. Decreasing tidal volume would worsen the acidosis. Increasing FiO2
addresses hypoxemia, not hypercapnia. Decreasing PEEP could worsen oxygenation.
4. A 72-year-old female is admitted to the ICU with a diagnosis of acute respiratory distress syndrome
(ARDS) secondary to severe pancreatitis. She is intubated and on mechanical ventilation. Her plateau
pressure is 32 cm H2O. Which of the following is the most appropriate intervention?
A. Increase the PEEP to 18 cm H2O.
B. Decrease the tidal volume to 6 mL/kg.
C. Switch to pressure-controlled ventilation.
D. Administer a neuromuscular blocking agent.
