Section 1: Assessment & Diagnosis (Questions 1-25)
Question 1
A 58-year-old male presents with crushing substernal chest pain radiating to the left
arm, diaphoresis, and nausea. His EKG shows ST-segment elevation in leads V1-V4.
Which cardiac biomarker rises first and is most specific for acute myocardial infarction?
A. Creatine kinase-MB (CK-MB)
B. Myoglobin
C. Troponin I
D. B-type natriuretic peptide (BNP)
C. Troponin I [CORRECT]
Rationale: Troponin I rises within 3-6 hours of myocardial injury, peaks at 12-24 hours,
and remains elevated for 7-10 days, making it the most specific and sensitive biomarker
for acute MI. CK-MB (Option A) rises within 4-6 hours but is less specific and has been
largely replaced by troponins. Myoglobin (Option B) rises within 1-2 hours but is
nonspecific (found in skeletal muscle). BNP (Option D) indicates ventricular stretch and
heart failure, not acute MI. This patient has anterior STEMI (V1-V4 = left anterior
descending territory). ANCC FNP Competency: Cardiovascular assessment and
diagnostic interpretation. Evidence-based guideline: ACC/AHA STEMI guidelines
recommend troponin as the preferred biomarker. Safety consideration: Immediate
reperfusion therapy is indicated for STEMI.
,Question 2
A 42-year-old female presents with sharp, pleuritic chest pain worsened by inspiration,
tachypnea, and mild hypoxemia. She recently returned from a long international flight.
Which diagnostic study is most appropriate to confirm the suspected diagnosis?
A. Chest X-ray
B. D-dimer assay
C. CT pulmonary angiography (CTPA)
D. Echocardiogram
C. CT pulmonary angiography (CTPA) [CORRECT]
Rationale: CTPA is the gold standard for diagnosing pulmonary embolism (PE),
providing direct visualization of pulmonary artery filling defects. This patient's
presentation (pleuritic chest pain, tachypnea, hypoxemia, recent long flight = Virchow's
triad: stasis) is classic for PE. Chest X-ray (Option A) is often normal or shows
nonspecific findings. D-dimer (Option B) is sensitive but nonspecific and used to rule
out PE in low-probability patients; it would likely be elevated here but does not confirm
PE. Echocardiogram (Option D) assesses right heart strain but does not definitively
diagnose PE. ANCC FNP Competency: Pulmonary embolism diagnosis. Evidence-based
guideline: CHEST guidelines recommend CTPA as the initial imaging test for suspected
PE in patients with intermediate to high pretest probability. Safety consideration: If
CTPA is contraindicated (renal impairment, contrast allergy), V/Q scan is alternative.
Question 3
A 35-year-old male presents with sudden-onset severe headache, described as "the
worst headache of my life," with photophobia and nuchal rigidity. Which action should
the FNP take first?
A. Administer sumatriptan for migraine treatment
B. Order a non-contrast head CT scan
C. Perform a lumbar puncture immediately
D. Start propranolol for headache prophylaxis
B. Order a non-contrast head CT scan [CORRECT]
,Rationale: "Thunderclap headache" with meningeal signs (photophobia, nuchal
rigidity) is the classic presentation of subarachnoid hemorrhage (SAH). Non-contrast
head CT is the first-line imaging to detect blood in the subarachnoid space (sensitivity
>95% within 6 hours). Sumatriptan (Option A) is contraindicated in undifferentiated
severe headache. Lumbar puncture (Option C) is performed if CT is negative but clinical
suspicion remains high (xanthochromia). Propranolol (Option D) is for migraine
prophylaxis, not acute emergency. ANCC FNP Competency: Neurologic emergency
recognition and initial management. Evidence-based guideline: AHA/ASA guidelines
recommend emergent non-contrast CT for suspected SAH. Safety consideration: SAH
requires immediate neurosurgical consultation; delay in diagnosis increases mortality.
Question 4
A 28-year-old female presents with right lower quadrant pain, fever (101.2°F), anorexia,
and rebound tenderness at McBurney's point. Her WBC is 14,500/mm³ with left shift.
Which diagnosis is most likely?
A. Ovarian torsion
B. Ectopic pregnancy
C. Acute appendicitis
D. Pelvic inflammatory disease
C. Acute appendicitis [CORRECT]
Rationale: Classic presentation of acute appendicitis includes right lower quadrant
pain, fever, anorexia, rebound tenderness at McBurney's point (1/3 distance from
anterior superior iliac spine to umbilicus), and leukocytosis with left shift. Ovarian
torsion (Option A) causes sudden, severe unilateral pain with nausea/vomiting but
typically no fever or leukocytosis. Ectopic pregnancy (Option B) presents with
amenorrhea, vaginal bleeding, and unilateral pain; urine pregnancy test would be
positive. PID (Option D) causes bilateral lower abdominal pain, vaginal discharge, and
cervical motion tenderness. ANCC FNP Competency: Abdominal pain differential
diagnosis. Evidence-based guideline: Alvarado score and imaging (CT or ultrasound)
guide diagnosis; surgical consultation is indicated. Safety consideration: Perforation risk
increases after 48 hours; prompt surgical evaluation is essential.
, Question 5
A 65-year-old male with a history of atrial fibrillation presents with sudden-onset left-
sided weakness, facial droop, and slurred speech. His symptoms began 2 hours ago.
Which is the priority intervention?
A. Administer aspirin 325 mg immediately
B. Obtain a non-contrast head CT to rule out hemorrhage
C. Start heparin infusion for anticoagulation
D. Perform a carotid ultrasound
B. Obtain a non-contrast head CT to rule out hemorrhage [CORRECT]
Rationale: In suspected acute ischemic stroke, non-contrast head CT is the first priority
to differentiate ischemic from hemorrhagic stroke before initiating thrombolytic
therapy (tPA/alteplase within 4.5 hours). Aspirin (Option A) is given after hemorrhage
is excluded. Heparin (Option C) is not first-line for acute ischemic stroke and is
contraindicated if hemorrhage is present. Carotid ultrasound (Option D) is part of
stroke workup but not the immediate priority. This patient is within the therapeutic
window for thrombolysis. ANCC FNP Competency: Stroke recognition and emergency
management. Evidence-based guideline: AHA/ASA stroke guidelines recommend CT
within 25 minutes of arrival; door-to-needle time for tPA ≤60 minutes. Safety
consideration: Hemorrhagic stroke must be excluded before thrombolysis to prevent
catastrophic bleeding.
Question 6
A 50-year-old female presents with epigastric pain radiating to the back, nausea, and
vomiting. Her serum lipase is 1,200 U/L (normal <160). Which etiology is most common
in the United States?
A. Gallstones
B. Alcohol abuse
