, SECTION 1: DIAGNOSTIC REASONING AND CLINICAL HYPOTHESIS GENERATION
Q1
A 42-year-old woman presents to the primary care clinic with a 3-week history of intermittent right upper quadrant
discomfort that worsens after fatty meals. She denies fever, jaundice, or changes in stool color. The nurse practitioner
begins formulating a differential diagnosis. Which approach best prioritizes life-threatening conditions while considering
the most probable etiologies?
A. List only the single most likely diagnosis based on classic textbook presentation before ordering any tests.
B. Generate a differential that first excludes serious conditions such as choledocholithiasis or malignancy, then ranks
probable functional and biliary disorders.
C. Order an immediate abdominal CT for every patient with right upper quadrant pain regardless of associated symptoms.
D. Defer hypothesis generation until all laboratory and imaging results return to avoid premature closure.
Correct Answer: B
Rationale:
Effective differential diagnosis requires systematic exclusion of serious or life-threatening conditions first while simultaneously
considering the most probable diagnoses based on history and epidemiology. Premature narrowing to one diagnosis or delaying
hypothesis formation until tests return increases the risk of missed critical pathology and diagnostic error.
Q2
A 28-year-old man reports a 5-day history of sore throat, low-grade fever, and fatigue. The nurse practitioner uses the
Centor criteria to guide decision-making. The patient has tonsillar exudates and tender anterior cervical
lymphadenopathy but no cough. Which statement best reflects the role of clinical prediction rules in differential
diagnosis?
A. Clinical prediction rules eliminate the need for any further testing once a score is calculated.
B. Clinical prediction rules provide structured probability estimates that help refine the differential and guide selective
testing.
C. Clinical prediction rules are only valid when the patient has all classic symptoms of streptococcal pharyngitis.
D. Clinical prediction rules should be ignored if the clinician's gestalt suggests a different diagnosis.
Correct Answer: B
Rationale:
Clinical prediction rules such as the Centor criteria quantify the probability of a specific diagnosis and support selective testing rather
than replace clinical judgment. They refine the differential by incorporating key predictors while still allowing clinician gestalt and
additional data to influence final decisions.
Q3
A 55-year-old woman with a history of hypertension presents with progressive fatigue and mild dyspnea on exertion
over 6 weeks. Initial laboratory studies reveal a hemoglobin of 9.8 g/dL. The nurse practitioner is constructing a
differential for anemia. Which step is most critical in avoiding diagnostic error at this stage?
A. Immediately start empiric iron supplementation without further characterization of the anemia.
B. Classify the anemia by red-cell indices and reticulocyte count before generating focused differentials for microcytic,
normocytic, or macrocytic causes.
C. Assume the anemia is due to chronic disease related to hypertension and forgo additional work-up.
D. Order a bone-marrow biopsy as the first diagnostic test for all patients with anemia of unknown origin.
Correct Answer: B
Rationale:
Proper classification of anemia by mean corpuscular volume and reticulocyte response narrows the differential into biologically
coherent categories and prevents premature or inappropriate empiric therapy. Starting iron without characterization or assuming a
single etiology increases the chance of missing alternative serious causes.

Q4
A 34-year-old previously healthy woman describes episodic palpitations lasting 2–3 minutes that resolve
spontaneously. She has no syncope, chest pain, or family history of sudden death. The nurse practitioner considers
both cardiac and non-cardiac etiologies. Which principle best guides the initial differential prioritization?
A. All palpitations in adults require immediate referral to cardiology before any primary-care evaluation.
B. Serious cardiac causes must be considered and stratified by risk features even when the pretest probability appears low.
C. Non-cardiac causes such as anxiety can be assumed once the patient reports resolution with rest.
D. Holter monitoring is mandatory for every patient reporting palpitations regardless of frequency or associated symptoms.
Correct Answer: B
Rationale:
Even when the overall probability of serious disease is low, life-threatening cardiac etiologies must remain on the differential until
adequately evaluated through history, examination, and targeted testing. Assuming benign etiology solely from symptom resolution
risks missing intermittent but dangerous arrhythmias.
Q5
A 61-year-old man with type 2 diabetes presents with a 10-day history of progressive bilateral lower-extremity edema.
The nurse practitioner expands the differential beyond simple venous insufficiency. Which additional historical element
most effectively narrows competing systemic diagnoses?
A. Whether the patient prefers to sleep on the left or right side.
B. Presence or absence of orthopnea, paroxysmal nocturnal dyspnea, and changes in exercise tolerance.
C. Exact brand of compression stockings previously tried.
D. Preferred time of day for taking antihypertensive medication.
Correct Answer: B
Rationale:
Symptoms of orthopnea and paroxysmal nocturnal dyspnea help differentiate cardiac causes of edema from primary venous or renal
etiologies. Targeted cardiovascular history is therefore high-yield in refining the differential for bilateral edema in a patient with
diabetes.
Q6
A 19-year-old college student reports a 4-day history of fever, myalgias, and nonproductive cough. Several dormitory
contacts have similar symptoms. The nurse practitioner considers both viral and atypical bacterial pathogens. Which
statement best describes the value of epidemiologic context in differential diagnosis?
A. Epidemiologic context is irrelevant once individual symptoms are catalogued.
B. Shared exposures and outbreak patterns raise the pretest probability of certain infectious agents and appropriately
influence testing and empiric decisions.
C. Epidemiologic data should only be considered after laboratory confirmation of a pathogen.
D. All febrile respiratory illnesses in young adults must be treated as influenza until proven otherwise.
Correct Answer: B
Rationale:
Epidemiologic information such as dormitory clustering increases the likelihood of specific pathogens and supports rational testing
and infection-control decisions. Ignoring context or defaulting to a single diagnosis without data both degrade diagnostic accuracy.
