Introduction
,The NR-569 Adult-Gerontology Acute Care I examination
assesses the advanced knowledge and clinical reasoning skills
required for formulating differential diagnoses in acute care
settings. This examination evaluates competency in
hypothesis-driven diagnostic reasoning, comprehensive
patient assessment, pattern recognition, and evidence-based
clinical decision-making. The test employs multiple-choice
and scenario-based questions that simulate high-acuity
clinical encounters involving critically ill adults and older
adults. Emphasis is placed on processing patient information
in a logical, progressive manner, identifying red flags,
prioritizing life-threatening conditions, and developing
comprehensive differential diagnoses. Candidates must
demonstrate the ability to synthesize complex clinical data,
recognize diagnostic errors, and implement safe, effective,
and ethically sound diagnostic strategies consistent with the
AGACNP scope of practice.
SECTION ONE: QUESTIONS 1–100
1. A 72-year-old female presents to the acute care clinic
with acute onset confusion, urinary frequency, and low-
grade fever. Her daughter reports she has been "forgetting
things all morning." Vitals: T 38.1°C, HR 102, BP 124/78, RR
,18, SpO2 96%. Using the NGN Clinical Judgment Model,
the AGACNP first recognizes cues from the presenting
symptoms. Which hypothesis should the AGACNP
prioritize as most plausible given the atypical presentation
in this elderly patient?
A. Acute ischemic stroke given the confusion and cognitive
changes
B. Urinary tract infection with subsequent delirium
superimposed on possible baseline cognitive impairment
C. Sepsis from a pulmonary source requiring immediate
broad-spectrum antibiotics
D. Acute hypoactive hyperthyroidism precipitating thyroid
storm with altered mental status
🟢 Correct answer: B
🔴 RATIONALE: Elderly patients frequently present
atypically, and UTI is one of the most common reversible
causes of acute delirium in this population, manifesting with
cognitive changes rather than classic dysuria. Acute stroke is
less likely without focal neurologic deficits, and thyroid
storm typically presents with hyperthermia, tachycardia, and
agitation rather than lethargy. Sepsis is premature without
evidence of hypotension, elevated lactate, or end-organ
hypoperfusion.
, 2. A 55-year-old male presents with substernal chest
pressure radiating to the left arm, diaphoresis, and
dyspnea that began 30 minutes ago while shoveling snow.
PMH: hypertension, hyperlipidemia, type 2 diabetes. The
AGACNP recognizes this as a classic pattern of ACS. Which
diagnostic reasoning process is most responsible for rapid
identification of this high-risk presentation?
A. Analytic (hypothetico-deductive) reasoning requiring
systematic testing of multiple hypotheses
B. Pattern recognition (System 1 thinking) based on illness
scripts acquired through clinical experience
C. Bayesian probabilistic reasoning using pre-test probability
and likelihood ratios
D. Diagnostic algorithms applied step-by-step from a chest
pain clinical decision tool
🟢 Correct answer: B
🔴 RATIONALE: Pattern recognition, or System 1 intuitive
thinking, allows experienced clinicians to rapidly match a
presentation to a stored illness script—a cognitive template
built from repeated clinical exposure. The classic
presentation of ACS represents a prototypical pattern
requiring rapid activation of the ACS pathway.
