Exam Description
This comprehensive examination is designed for candidates preparing for the American
Nurses Credentialing Center (ANCC) Adult-Gerontology Acute Care Nurse Practitioner
(AGACNP) Board Certification Examination for the 2026/2027 testing cycle . The exam
follows the ANCC test content outline covering Core Competencies (24%), Clinical
Practice (43%), and Professional Role (33%) domains . Topics include advanced
pathophysiology, pharmacology, diagnostic reasoning, cardiovascular, endocrine,
pulmonary, renal, neurological, and ethical-legal management . The exam contains 175
questions (150 scored + 25 pretest) with detailed rationales to strengthen clinical
judgment and exam confidence. Each question includes a detailed rationale to reinforce
evidence-based practice essential for AGACNP certification.
Section 1: Core Competencies – Advanced Health Assessment and Diagnostics (Questions
1-50)
Question 1
A 72-year-old male presents with acute onset of severe chest pain radiating to the back,
with a blood pressure of 190/110 mmHg and pulse of 102 bpm. Which diagnostic test is
MOST appropriate to confirm the suspected diagnosis?
A. CT angiography of the chest
B. ECG with troponin
C. Chest X-ray
D. Transesophageal echocardiogram
Answer: A. CT angiography of the chest
Rationale: Acute aortic dissection presents with severe chest pain radiating to the back,
hypertension, and pulse deficit. CT angiography is the imaging study of choice to confirm
aortic dissection. ECG and troponin are appropriate for MI, and chest X-ray has limited
sensitivity for dissection .
,Question 2
A 65-year-old patient with a history of heart failure presents with worsening dyspnea,
JVD, and crackles in the lungs. Which diagnostic test is most useful to confirm volume
overload?
A. B-type natriuretic peptide (BNP)
B. Chest X-ray
C. Echocardiogram
D. Pulmonary artery catheterization
Answer: A. B-type natriuretic peptide (BNP)
Rationale: BNP is released from ventricular myocytes in response to increased wall
tension and volume overload. Elevated BNP confirms heart failure and volume overload.
BNP >100 pg/mL is suggestive of heart failure .
Question 3
A patient is being evaluated for adrenal insufficiency. Which test is the gold standard for
diagnosis?
A. Serum cortisol level
B. ACTH stimulation test (Cosyntropin stimulation test)
C. 24-hour urine cortisol
D. ACTH level
Answer: B. ACTH stimulation test (Cosyntropin stimulation test)
Rationale: The cosyntropin stimulation test is the gold standard for diagnosing adrenal
insufficiency. A subnormal cortisol response indicates adrenal insufficiency. This is a
common high-yield topic on the AGACNP exam .
Question 4
A 68-year-old patient presents with confusion, headache, and papilledema. Blood
pressure is 210/120 mmHg. Which diagnosis is MOST likely?
A. Hypertensive urgency
B. Hypertensive emergency with target organ damage
C. Malignant hypertension without end-organ damage
D. Essential hypertension
Answer: B. Hypertensive emergency with target organ damage
,Rationale: Hypertensive emergency is defined as severe hypertension (>180/120 mmHg)
with evidence of acute target organ damage. Neurological symptoms and papilledema
indicate cerebral edema and end-organ damage .
Question 5
Which laboratory finding is most consistent with syndrome of inappropriate antidiuretic
hormone (SIADH)?
A. Serum sodium 118 mEq/L, urine osmolality 600 mOsm/kg
B. Serum sodium 155 mEq/L, urine osmolality 150 mOsm/kg
C. Serum sodium 135 mEq/L, urine osmolality 300 mOsm/kg
D. Serum sodium 145 mEq/L, urine osmolality 100 mOsm/kg
Answer: A. Serum sodium 118 mEq/L, urine osmolality 600 mOsm/kg
Rationale: SIADH causes hyponatremia with inappropriately concentrated urine (urine
osmolality >100 mOsm/kg despite low serum sodium). Urine sodium is typically elevated.
The finding of low serum sodium and high urine osmolality is classic for SIADH .
Question 6
A patient with suspected diabetes insipidus undergoes a water deprivation test. Which
finding is most consistent with central diabetes insipidus?
A. Urine osmolality >800 mOsm/kg
B. Urine osmolality <300 mOsm/kg that increases after desmopressin administration
C. Urine osmolality decreases after desmopressin administration
D. Serum osmolality <275 mOsm/kg
Answer: B. Urine osmolality <300 mOsm/kg that increases after desmopressin
administration
Rationale: In central diabetes insipidus, the water deprivation test reveals dilute urine
that becomes concentrated after administration of desmopressin (ADH analog). This
distinguishes central DI from nephrogenic DI .
Question 7
A 55-year-old female presents with fatigue, weight gain, and cold intolerance. TSH is 8.5
mIU/L. Which is the most appropriate next step?
A. Start levothyroxine replacement
B. Order thyroid ultrasound
, C. Check free T4 and T3 levels
D. Repeat TSH in 6 months
Answer: C. Check free T4 and T3 levels
Rationale: An elevated TSH suggests primary hypothyroidism. Checking free T4 and T3
levels confirms the diagnosis and guides treatment. Levothyroxine is the treatment of
choice, but confirmation with free T4 is important .
Question 8
A 72-year-old male with dementia requires long-term care placement. After "spending
down" his assets, which funding agency should the patient apply to for coverage?
A. Medicare
B. Medicaid
C. TRICARE
D. Private insurance
Answer: B. Medicaid
Rationale: Medicaid covers long-term care costs after patients "spend down" their assets.
Medicare does not cover long-term custodial care. This is a common AGACNP exam
question regarding healthcare policy and resource utilization .
Question 9
Which of the following is the most important factor to evaluate when determining
statistical significance in a research study?
A. Sample size
B. Confidence interval
C. P-value compared to alpha coefficient
D. Effect size
Answer: A. Sample size
Rationale: Sample size is critical in evaluating statistical significance. A study with an
inadequate sample size may lack power to detect significant differences even if they exist.
This is a fundamental research principle tested on the AGACNP exam .
