Section 1: Assessment & Diagnostic Reasoning (Questions 1-20)
Q1. A 68-year-old male presents with acute onset of severe, tearing chest pain
radiating to his back. His blood pressure is 185/110 mmHg in the right arm and
160/95 mmHg in the left arm. A chest X-ray shows a widened mediastinum. What
is the MOST appropriate next step?
A. Administer IV heparin and obtain CT pulmonary angiography
B. Obtain emergent non-contrast head CT
C. Obtain emergent CT angiography of the chest
D. Administer IV thrombolytics and obtain echocardiogram
Correct Answer: C. Obtain emergent CT angiography of the chest [CORRECT]
Rationale: This presentation is classic for aortic dissection: tearing chest/back pain,
pulse deficit, blood pressure differential >20 mmHg between arms, and widened
mediastinum on CXR. CT angiography (CTA) is the gold standard for diagnosis.
Option A is incorrect because anticoagulation is contraindicated in aortic dissection
and CTPA evaluates for PE, not dissection. Option B evaluates for subarachnoid
hemorrhage, which presents with thunderclap headache, not tearing chest pain.
Option D is incorrect because thrombolytics are absolutely contraindicated in aortic
dissection and would be catastrophic. ANCC FNP competency: Differentiate life-
threatening cardiovascular emergencies requiring immediate diagnostic imaging.
Evidence-based guideline: AHA/ACC 2022 Aortic Disease Guidelines recommend CTA
as first-line imaging for suspected acute aortic syndrome.
,Q2. A 42-year-old female presents with sudden-onset "worst headache of my life,"
neck stiffness, photophobia, and vomiting. She is alert and oriented. What is the
BEST initial diagnostic step?
A. Perform lumbar puncture immediately
B. Obtain non-contrast head CT within 6 hours of symptom onset
C. Administer IV antibiotics and obtain MRI brain with contrast
D. Obtain CT angiography of the head and neck
Correct Answer: B. Obtain non-contrast head CT within 6 hours of symptom onset
[CORRECT]
Rationale: This presentation is classic for subarachnoid hemorrhage (SAH). Non-
contrast head CT is the initial imaging of choice and has near 100% sensitivity within
6 hours of symptom onset. Option A is incorrect because LP should only be
performed if CT is negative after 6 hours or if CT is inconclusive. Option C is incorrect
because MRI is not the initial test for SAH and antibiotics are not indicated without
evidence of meningitis. Option D evaluates for vascular causes but is not the first
step; CTA may follow if CT is negative and SAH is still suspected. ANCC FNP
competency: Prioritize diagnostic testing for acute neurological emergencies.
Evidence-based guideline: AHA/ASA 2021 SAH Guidelines recommend non-contrast
head CT as initial imaging.
Q3. A 28-year-old male presents with acute scrotal pain, nausea, and vomiting. On
examination, the left testis is high-riding with a horizontal lie, and the
cremasteric reflex is absent. What is the MOST appropriate immediate action?
A. Administer IV antibiotics and schedule outpatient urology follow-up in 48 hours
B. Obtain Doppler ultrasound immediately and await results before intervention
C. Perform manual detorsion and schedule elective orchiopexy
D. Obtain emergent urology consultation for immediate surgical exploration
Correct Answer: D. Obtain emergent urology consultation for immediate surgical
exploration [CORRECT]
,Rationale: This is classic testicular torsion: acute scrotal pain, nausea/vomiting,
absent cremasteric reflex, high-riding testis, and horizontal lie. Time is critical;
testicular viability decreases significantly after 6 hours. Option A is incorrect because
antibiotics treat infection, not torsion. Option B is dangerous because waiting for
ultrasound results wastes precious time; ultrasound can confirm but should not delay
intervention if clinical suspicion is high. Option C is incorrect because manual
detorsion is temporizing at best and does not replace definitive surgical exploration
and bilateral orchiopexy. ANCC FNP competency: Recognize surgical emergencies
requiring immediate specialist intervention. Evidence-based guideline: AUA
Guidelines recommend immediate surgical exploration for suspected testicular
torsion without awaiting imaging if clinical presentation is classic.
Q4. A 55-year-old female with a history of lumbar disc herniation presents with
new-onset saddle anesthesia, urinary retention, and bilateral leg weakness. What
is the MOST appropriate next step?
A. Schedule urgent outpatient MRI within 1 week
B. Obtain emergent MRI of the lumbosacral spine
C. Initiate high-dose oral prednisone and physical therapy referral
D. Perform lumbar puncture to evaluate for Guillain-Barré syndrome
Correct Answer: B. Obtain emergent MRI of the lumbosacral spine [CORRECT]
Rationale: Saddle anesthesia, urinary retention, fecal incontinence, and bilateral leg
weakness constitute cauda equina syndrome, a surgical emergency requiring
emergent MRI to confirm compression and immediate neurosurgical consultation.
Option A delays definitive diagnosis and risks permanent neurological damage.
Option C treats inflammation but does not address the emergent nature of cord
compression. Option D is incorrect because Guillain-Barré presents with ascending
weakness and areflexia, not saddle anesthesia and urinary retention. ANCC FNP
competency: Identify red flags requiring emergent imaging and surgical referral.
Evidence-based guideline: NICE Guidelines and AANS recommend emergent MRI for
suspected cauda equina syndrome.
, Q5. A 35-year-old female presents with fever, severe headache, nuchal rigidity,
and altered mental status. Kernig and Brudzinski signs are positive. What is the
BEST immediate management?
A. Obtain CT head before any other intervention
B. Administer empiric IV antibiotics and obtain blood cultures, then perform lumbar
puncture within 30 minutes
C. Administer IV dexamethasone only and monitor in ICU
D. Obtain MRI brain with and without contrast before lumbar puncture
Correct Answer: B. Administer empiric IV antibiotics and obtain blood cultures,
then perform lumbar puncture within 30 minutes [CORRECT]
Rationale: This is classic bacterial meningitis. Empiric antibiotics should not be
delayed for imaging if the patient has no contraindications to LP (no papilledema, no
focal deficits, no immunocompromise, no history of CNS disease, no new-onset
seizure). LP should be performed within 30 minutes of presentation. Option A delays
antibiotics, which increases mortality. Option C is insufficient because steroids alone
do not treat the infection. Option D is unnecessarily time-consuming; MRI is not
required before LP in uncomplicated cases. ANCC FNP competency: Prioritize time-
sensitive interventions for life-threatening infections. Evidence-based guideline: IDSA
2004 Meningitis Guidelines (still current) recommend LP within 30 minutes and
empiric antibiotics immediately if LP is delayed.
Q6. A 62-year-old male presents with chest pressure radiating to the left jaw and
arm, diaphoresis, dyspnea, and nausea. EKG shows ST-segment elevation in leads
V1-V4. Troponin is pending. What is the FIRST priority action?
A. Administer sublingual nitroglycerin and obtain CT coronary angiography
B. Administer aspirin 325 mg chewable, clopidogrel 600 mg loading dose, and
activate the cardiac catheterization lab immediately
C. Administer IV heparin bolus only and await troponin results
D. Administer IV thrombolytics in the emergency department
Correct Answer: B. Administer aspirin 325 mg chewable, clopidogrel 600 mg
loading dose, and activate the cardiac catheterization lab immediately [CORRECT]
