Introduction
,This comprehensive examination is designed to prepare candidates for the Adult-Gerontology Acute Care Nurse
Practitioner certification examination. The assessment evaluates advanced clinical knowledge, diagnostic acumen,
evidence-based management strategies, and professional role competencies required for safe and effective acute
care practice. Questions are presented in multiple-choice and clinical scenario-based formats that mirror the
structure and rigor of the actual board examination. Each question emphasizes real-world application, critical
thinking, and clinical decision-making in the acute and critical care setting. Detailed rationales are provided to
reinforce learning and solidify understanding of key concepts. Successful completion of this examination indicates
readiness for professional certification and independent acute care practice.
SECTION ONE: QUESTIONS 1 – 100
Question 1
A 72-year-old male with a history of hypertension and type 2 diabetes presents to the emergency department
with acute onset of severe chest pressure radiating to the jaw, accompanied by diaphoresis and nausea. An
electrocardiogram reveals 2-mm ST-segment elevations in leads V1–V4. Which intervention should the AGACNP
initiate FIRST?
A. Administer sublingual nitroglycerin 0.4 mg
B. Obtain a STAT troponin panel
C. Activate the cardiac catheterization team for emergent percutaneous coronary intervention
D. Administer aspirin 324 mg chewed
,🟢 D. Administer aspirin 324 mg chewed
🔴 RATIONALE: Aspirin is the first-line intervention for suspected acute ST-segment elevation myocardial
infarction (STEMI) because it reduces mortality by inhibiting platelet aggregation. While nitroglycerin, troponin
measurement, and catheterization are all critical components of STEMI management, aspirin administration
should occur immediately upon recognition of STEMI symptoms, even before the ECG is confirmed. Delaying
aspirin for other interventions can compromise patient outcomes. The American College of
Cardiology/American Heart Association guidelines recommend chewable aspirin 324 mg as the initial
pharmacologic therapy for STEMI.
Question 2
A 68-year-old female is admitted with acute exacerbation of chronic obstructive pulmonary disease. Arterial
blood gas reveals pH 7.28, PaCO2 68 mmHg, PaO2 55 mmHg, and HCO3 28 mEq/L. Which of the following is
the MOST appropriate initial intervention?
A. Administer 100% non-rebreather mask oxygen
B. Initiate bi-level positive airway pressure ventilation
C. Administer intravenous methylprednisolone
D. Intubate and initiate mechanical ventilation
🟢 B. Initiate bi-level positive airway pressure ventilation
🔴 RATIONALE: Noninvasive positive pressure ventilation (NPPV), specifically bi-level positive airway pressure
(BiPAP), is the standard of care for acute hypercapnic respiratory failure in COPD exacerbations with pH < 7.35
, and PaCO2 > 45 mmHg. BiPAP reduces the need for intubation and improves outcomes. While corticosteroids
are indicated, they are not the initial emergent intervention. High-flow oxygen can suppress respiratory drive
and worsen hypercapnia. Intubation is reserved for patients who fail NPPV or have contraindications to its use.
Question 3
Which of the following is the MOST reliable indicator of adequate tissue perfusion in a patient with septic
shock?
A. Mean arterial pressure ≥ 65 mmHg
B. Central venous oxygen saturation ≥ 70%
C. Urine output ≥ 0.5 mL/kg/hour
D. Serum lactate < 2 mmol/L
🟢 B. Central venous oxygen saturation ≥ 70%
🔴 RATIONALE: Central venous oxygen saturation (ScvO2) reflects the balance between oxygen delivery and
consumption and is a sensitive indicator of tissue perfusion. While MAP, urine output, and lactate are important
parameters, ScvO2 ≥ 70% is the most reliable early indicator of adequate resuscitation in septic shock, as it
directly measures the adequacy of oxygen delivery relative to tissue demand. The Surviving Sepsis Campaign
guidelines specifically target ScvO2 ≥ 70% as a resuscitation endpoint.
