Subject Area Advanced Health Assessment and Diagnostic Reasoning
Description This exam assesses the ability to integrate advanced health assessment findings
with diagnostic reasoning in complex clinical scenarios. It emphasizes
interpretation of physical examination data, selection and interpretation of
diagnostic tests, and clinical decision-making for differential diagnoses.
Expected Grade A+
Total Questions 200
Duration 3 hours
Learning Outcomes 1. Synthesize comprehensive health history and physical exam data to formulate
differential diagnoses.
2. Select and interpret appropriate diagnostic tests based on clinical presentation
and evidence-based guidelines.
3. Apply clinical reasoning to prioritize diagnoses and management in acute and
chronic conditions.
4. Differentiate between normal variants and pathological findings across body
systems.
Accreditation Meets AACN Essentials for Doctor of Nursing Practice (DNP) and Commission
on Collegiate Nursing Education (CCNE) standards.

,1. A patient presents with sudden onset of severe, tearing chest pain radiating to the
back, with a blood pressure difference of 25 mmHg between arms. Which of the
following diagnostic studies is most appropriate to confirm the suspected diagnosis?
A. High-resolution CT angiography of the chest
B. Transthoracic echocardiogram with color Doppler
C. Ventilation-perfusion (V/Q) scan
D. Exercise stress echocardiogram
Answer: A. High-resolution CT angiography of the chest
High-resolution CT angiography is the gold standard for diagnosing aortic dissection
due to its high sensitivity and specificity. Echocardiography may miss distal dissections.
V/Q scan is for pulmonary embolism. Stress echo is contraindicated in acute aortic
syndromes.
2. A patient with chronic liver disease presents with asterixis and confusion.
Laboratory results show elevated ammonia levels. Which of the following
pathophysiological mechanisms best explains the neurological symptoms?
A. Accumulation of glutamine in astrocytes causing cerebral edema
B. Direct neurotoxicity of ammonia via NMDA receptor activation
C. Decreased synthesis of neurotransmitters due to impaired urea cycle
D. Increased permeability of the blood-brain barrier to toxins
Answer: A. Accumulation of glutamine in astrocytes causing cerebral edema
In hepatic encephalopathy, ammonia is metabolized to glutamine in astrocytes, leading
to osmotic swelling and cerebral edema. While NMDA activation plays a role, the
primary mechanism is glutamine-induced astrocyte swelling. Options C and D are
secondary contributors.

,3. A patient with a history of heart failure presents with progressive dyspnea,
bilateral crackles, and an S3 gallop. Which of the following hemodynamic
parameters is most likely to be consistent with this clinical presentation?
A. Pulmonary artery wedge pressure 8 mmHg, cardiac index 2.8 L/min/m²
B. Pulmonary artery wedge pressure 25 mmHg, cardiac index 1.8 L/min/m²
C. Pulmonary artery wedge pressure 12 mmHg, cardiac index 4.0 L/min/m²
D. Pulmonary artery wedge pressure 30 mmHg, cardiac index 3.5 L/min/m²
Answer: B. Pulmonary artery wedge pressure 25 mmHg, cardiac index 1.8
L/min/m²
Elevated wedge pressure (>18 mmHg) indicates pulmonary congestion; low cardiac
index (<2.2) suggests reduced cardiac output. Option B shows both, consistent with
acute decompensated heart failure with low output. Options A and C have normal
wedge pressure; D has high wedge but normal cardiac index, less likely in this scenario.
4. A patient presents with acute onset of pleuritic chest pain, dyspnea, and
hemoptysis. A CT pulmonary angiogram reveals a filling defect in the right main
pulmonary artery. Which of the following electrocardiogram findings is most
specific for this condition?
A. S1Q3T3 pattern
B. Right bundle branch block
C. T-wave inversion in leads V1-V4
D. P pulmonale
Answer: A. S1Q3T3 pattern
S1Q3T3 (deep S in lead I, Q wave and inverted T in lead III) is classic for acute
pulmonary embolism, though not highly sensitive. Right bundle branch block and
T-wave inversions can occur but are less specific. P pulmonale indicates right atrial
enlargement, seen in chronic pulmonary hypertension.

, 5. A patient with suspected adrenal insufficiency undergoes an ACTH stimulation
test. Baseline cortisol is 3 mcg/dL; 30 minutes after cosyntropin, cortisol is 8 mcg/dL.
Which of the following best interprets this result?
A. Normal response, excluding adrenal insufficiency
B. Primary adrenal insufficiency
C. Secondary adrenal insufficiency
D. Indeterminate, requires further testing
Answer: C. Secondary adrenal insufficiency
A normal response is cortisol >18 mcg/dL after stimulation. A subnormal response
(<18) indicates adrenal insufficiency. In primary insufficiency, baseline cortisol is low
and response is blunted (<10). In secondary, baseline may be low but response is often
present but subnormal. Here, a rise from 3 to 8 suggests some adrenal reserve,
consistent with secondary (pituitary) insufficiency.
6. A patient with a history of type 2 diabetes mellitus presents with acute onset of
severe right flank pain radiating to the groin, associated with nausea and hematuria.
A non-contrast CT scan shows a 5 mm stone at the ureterovesical junction. Which of
the following is the most appropriate initial management?
A. Extracorporeal shock wave lithotripsy
B. Ureteroscopy with laser lithotripsy
C. Medical expulsive therapy with tamsulosin and hydration
D. Percutaneous nephrolithotomy
Answer: C. Medical expulsive therapy with tamsulosin and hydration
For distal ureteral stones <10 mm, medical expulsive therapy (alpha-blockers) plus
hydration is first-line, as most pass spontaneously. ESWL and ureteroscopy are
reserved for stones that fail to pass or are >10 mm. Percutaneous nephrolithotomy is
for large or complex renal stones.
