Introduction
The NR 511 Differential Diagnosis and Primary Care Practicum Final
Examination evaluates the advanced practice nursing student's ability to
synthesize subjective and objective data to formulate prioritized differential
diagnoses. The assessment measures competency in diagnostic reasoning,
evidence-based test selection, and the application of clinical practice guidelines
to common and atypical presentations of acute and chronic conditions.
Questions are scenario-based and require the integration of pathophysiology,
,pharmacotherapeutics, and patient-centered care planning. The examination
emphasizes the recognition of red flags, urgent referrals, and the formulation
of comprehensive management plans. Success demands critical thinking,
pattern recognition, and the translation of evidence into safe, effective primary
care decisions.
SECTION ONE: QUESTIONS 1–100
Question 1
A 55-year-old male presents with acute onset of severe, tearing chest pain
radiating to his back. Blood pressure in the right arm is 180/100 mmHg, and
in the left arm it is 140/80 mmHg. Which condition should be at the top of
the differential diagnosis?
A. Acute myocardial infarction
B. Pulmonary embolism
C. Aortic dissection
D. Pericarditis
C. Aortic dissection
RATIONALE: Aortic dissection classically presents with sudden, severe
tearing chest pain radiating to the back, accompanied by a pulse differential
of greater than 20 mmHg between arms. This is a "cannot miss" diagnosis
requiring emergent surgical evaluation.
Question 2
A 42-year-old female presents with fatigue, weight gain, and constipation.
TSH is 8.5 mIU/L (elevated), and free T4 is 0.9 ng/dL (low-normal). Which
diagnostic reasoning principle best applies?
A. Sensitivity of TSH is insufficient for diagnosis
B. Specific pattern recognition confirms primary hypothyroidism
C. Free T4 is the most sensitive screening test
D. TSH elevation indicates secondary hypothyroidism
, B. Specific pattern recognition confirms primary hypothyroidism
RATIONALE: The combination of symptoms with elevated TSH and low-
normal free T4 represents pattern recognition for primary hypothyroidism.
TSH is the most sensitive screening test for thyroid dysfunction. Secondary
hypothyroidism would present with low or inappropriately normal TSH.
Question 3
A 28-year-old male presents with acute scrotal pain and swelling. Physical
exam reveals a high-riding testis and absent cremasteric reflex. Doppler
ultrasound is not immediately available. Which principle guides immediate
management?
A. Wait for imaging confirmation before intervention
B. Time-critical diagnosis requires surgical exploration without imaging delay
C. Antibiotics should be started empirically
D. Pain medication should be administered and patient observed
B. Time-critical diagnosis requires surgical exploration without imaging
delay
RATIONALE: Testicular torsion is a "cannot miss" diagnosis requiring
surgical detorsion within 6 hours to preserve testicular viability. When the
clinical presentation is highly suggestive and imaging is unavailable,
immediate surgical referral is indicated.
Question 4
A 68-year-old male with a 40-pack-year smoking history presents with a 2-
month history of progressive hoarseness. Which finding would most strongly
warrant urgent referral for laryngoscopy?
A. Symptoms improved with voice rest
B. Associated heartburn
C. History of recent upper respiratory infection
D. Persistent symptoms without improvement
, D. Persistent symptoms without improvement
RATIONALE: Persistent hoarseness lasting longer than 2 weeks in a
patient with significant smoking history requires urgent laryngoscopy to rule
out laryngeal carcinoma. Symptoms that do not resolve with conservative
management warrant further investigation.
Question 5
A 34-year-old teacher presents with sore throat, fever of 101.5°F, and fatigue
for 2 days. Exam shows erythematous tonsils with exudate and tender anterior
cervical lymphadenopathy. Which test is most appropriate to confirm the
diagnosis?
A. Rapid antigen detection test
B. Throat culture
C. Complete blood count
D. Monospot test
A. Rapid antigen detection test
RATIONALE: The clinical presentation is consistent with group A
streptococcal pharyngitis. Rapid antigen detection testing provides timely
results to guide antibiotic therapy. A throat culture may be used as backup for
negative rapid tests in certain populations.
Question 6
A 25-year-old patient presents with fatigue, cold intolerance, weight gain, and
constipation for 3 months. Exam reveals sinus bradycardia, coarse dry hair,
and delayed relaxation of deep tendon reflexes. Which test should be ordered
first?
A. Thyroid-stimulating hormone (TSH)
B. Complete blood count
C. Fasting glucose
D. Serum electrolytes
