PART 1: SYNTHESIZE SUBJECTIVE AND OBJECTIVE DATA TO FORMULATE
PRIORITIZED DIFFERENTIAL DIAGNOSES IN PRIMARY CARE
1. A patient with heart failure with reduced ejection fraction (HFrEF) is on maximally tolerated doses of
sacubitril/valsartan, carvedilol, and spironolactone but remains symptomatic (NYHA class III). Which addition is
most strongly supported by current evidence to reduce mortality?
A) Ivabradine
B) Dapagliflozin
C) Hydralazine/isosorbide dinitrate
D) Digoxin
' Correct Answer: B
Rationale: SGLT2 inhibitors (dapagliflozin, empagliflozin) are now guideline-directed medical therapy for HFrEF,
with proven mortality benefit when added to standard therapy. Ivabradine reduces hospitalization but not mortality;
hydralazine/nitrates are less effective than SGLT2i in this context; digoxin reduces hospitalizations but not mortality.
2. Which spirometric pattern is most consistent with a diagnosis of asthma in a symptomatic patient?
A) FEV1/FVC < 0.70 with significant reversibility after bronchodilator
B) FEV1/FVC > 0.70 with reduced FVC
C) Normal FEV1/FVC with increased total lung capacity
D) FEV1/FVC < 0.70 with no change after bronchodilator
' Correct Answer: A
Rationale: Asthma is characterized by variable airflow obstruction with reversibility ("e12% and "e200 mL increase
in FEV1). A fixed obstruction (D) suggests COPD; restrictive patterns (B, C) are not typical of asthma.

,3. A patient with type 2 diabetes has an HbA1c of 8.5% on metformin. Which add-on therapy offers the greatest
cardiovascular risk reduction in a patient with established atherosclerotic cardiovascular disease?
A) Sulfonylurea
B) DPP-4 inhibitor
C) GLP-1 receptor agonist
D) Insulin
' Correct Answer: C
Rationale: GLP-1 receptor agonists (e.g., liraglutide, semaglutide) have proven cardiovascular benefit in patients
with ASCVD. Sulfonylureas and DPP-4 inhibitors are cardiovascular neutral; insulin has no proven macrovascular
benefit.
4. Which finding on a 12-lead ECG is most specific for acute ST-elevation myocardial infarction (STEMI) in the
presence of left bundle branch block (LBBB)?
A) Concordant ST elevation 1 mm in leads with positive QRS
B) Discordant ST depression in leads V1-V3
C) Concordant ST depression 1 mm in leads V1-V3
D) Discordant ST elevation 5 mm in leads with negative QRS
' Correct Answer: A
Rationale: In LBBB, concordant ST elevation (in leads with positive QRS) is a specific sign of STEMI. Discordant
ST elevation is common in uncomplicated LBBB; concordant ST depression in V1-V3 is also abnormal but less
specific than concordant ST elevation.
5. A patient presents with acute monoarticular knee pain and swelling. Arthrocentesis reveals cloudy fluid, WBC
60,000/mm³ with 90% neutrophils, and no crystals. Which is the most appropriate next step?
A) Oral colchicine and NSAIDs
B) Intra-articular corticosteroid injection
C) Empiric IV antibiotics after cultures
D) MRI of the knee
' Correct Answer: C
Rationale: The presentation is consistent with septic arthritis (high WBC, neutrophil predominance). Empiric IV
antibiotics should be started after obtaining cultures. Colchicine/NSAIDs treat gout; steroids could worsen infection;
MRI is not the initial step.
6. A patient with major depressive disorder is started on sertraline. Which statement regarding sexual dysfunction is
most accurate?
A) It is uncommon with SSRIs and usually resolves within 2 weeks.
B) It is a class effect that may persist and can be managed with bupropion augmentation.
C) It is more common with bupropion than with SSRIs.
D) It is only seen at doses above 100 mg daily.
' Correct Answer: B
Rationale: SSRI-induced sexual dysfunction is common, may persist, and can be mitigated by adding bupropion.
Bupropion has low sexual side effects; the effect is not dose-dependent in the simple way described.
7. A 55-year-old woman with a 10-pack-year smoking history asks about lung cancer screening. According to the
2021 USPSTF guidelines, which criterion must be met?
A) Age 50-80, 20 pack-year history, currently smoking or quit within 15 years
B) Age 55-74, 30 pack-year history, currently smoking or quit within 15 years
C) Age 50-80, 20 pack-year history, currently smoking or quit within 10 years
Page 2
, D) Age 55-80, 30 pack-year history, currently smoking or quit within 10 years
' Correct Answer: A
Rationale: The 2021 USPSTF recommends annual low-dose CT for adults aged 50–80 with a 20 pack-year history
who currently smoke or quit within 15 years. The other options reflect older or incorrect criteria.
8. A patient with type 2 diabetes has an eGFR of 35 mL/min/1.73 m² and albuminuria. Which medication should be
avoided?
A) Empagliflozin
B) Metformin
C) Liraglutide
D) Losartan
' Correct Answer: B
Rationale: Metformin is contraindicated when eGFR <30 mL/min/1.73 m² and should be reassessed at eGFR
30-45. SGLT2 inhibitors, GLP-1 agonists, and ARBs are recommended for renal protection.
9. Which vaccine is contraindicated in a patient with a history of anaphylaxis to gelatin?
A) Inactivated influenza vaccine
B) Measles, mumps, rubella (MMR) vaccine
C) Tetanus, diphtheria, acellular pertussis (Tdap) vaccine
D) Hepatitis B vaccine
' Correct Answer: B
Rationale: MMR vaccine contains gelatin as a stabilizer and is contraindicated in individuals with severe gelatin
allergy. Influenza, Tdap, and hepatitis B vaccines do not typically contain gelatin.
10. A patient presents with a 3-day history of unilateral facial paralysis, inability to close the eye, and loss of taste on
the anterior tongue. Which finding would most suggest an alternative diagnosis to Bell's palsy?
A) Presence of a preceding upper respiratory infection
B) Involvement of only the lower half of the face
C) Hyperacusis in the affected ear
D) Gradual onset over 72 hours
' Correct Answer: B
Rationale: Bell's palsy typically affects the entire half of the face (upper and lower). Isolated lower facial weakness
suggests a central (upper motor neuron) lesion, such as stroke. The other findings are consistent with Bell's palsy.
11. A patient with newly diagnosed type 2 diabetes has an A1c of 7.4% and no contraindications. According to
current ADA/ACC standards, which pharmacologic strategy best aligns with evidence for reducing cardiovascular
and renal risk beyond glycemic control?
A) Initiate a sulfonylurea as first-line add-on to metformin for durable A1c reduction.
B) Add an SGLT2 inhibitor or GLP-1 receptor agonist with proven CV/renal benefit, independent of A1c.
C) Defer add-on therapy until A1c exceeds 8.5% to avoid polypharmacy.
D) Start basal insulin to target fasting glucose < 100 mg/dL before considering non-insulin agents.
' Correct Answer: B
Rationale: Current ADA/ACC guidance prioritizes SGLT2 inhibitors or GLP-1 RAs with demonstrated CV/renal
outcome benefits in patients with or at high risk for ASCVD, HF, or CKD, regardless of baseline A1c. Sulfonylureas
and insulin lack these organ-protective outcome data, and delaying add-on therapy until A1c > 8.5% ignores
cardiorenal risk. Basal insulin is not first-line for this scenario.
Page 3
, 12. A patient on lisinopril for hypertension develops a persistent dry cough. Which substitution best preserves
guideline-directed renin-angiotensin blockade while minimizing cough risk?
A) Switch to losartan.
B) Switch to aliskiren.
C) Add benzonatate and continue lisinopril.
D) Switch to spironolactone.
' Correct Answer: A
Rationale: ACE inhibitor cough is bradykinin-mediated; switching to an ARB (losartan) maintains
renin-angiotensin blockade without bradykinin accumulation. Aliskiren is a direct renin inhibitor with inferior
outcome data and similar hyperkalemia risk. Benzonatate treats symptoms without removing the cause, and
spironolactone is a diuretic/aldosterone antagonist, not a substitute for ACE/ARB therapy.
13. A patient with major depressive disorder has failed two adequate trials of SSRIs. Which next-step strategy is best
supported by current evidence for treatment-resistant depression?
A) Switch to a different SSRI and wait 12 weeks.
B) Augment with an atypical antipsychotic (e.g., aripiprazole) or switch to an SNRI.
C) Add a benzodiazepine for rapid symptom control.
D) Initiate thyroid hormone replacement regardless of TSH.
' Correct Answer: B
Rationale: After two failed SSRI trials, evidence supports augmentation with second-generation antipsychotics
(aripiprazole, quetiapine) or switching to a different class such as an SNRI. Switching to another SSRI is unlikely to
be effective after two failures. Benzodiazepines do not treat core depression, and thyroid augmentation requires
documented hypothyroidism.
14. A patient with heart failure with reduced ejection fraction (HFrEF) is stable on guideline-directed medical
therapy. Which combination is most consistent with current ACC/AHA/HFSA recommendations to reduce
mortality?
A) Sacubitril/valsartan, carvedilol, spironolactone, and dapagliflozin
B) Lisinopril, metoprolol tartrate, furosemide, and digoxin
C) Amlodipine, hydralazine, isosorbide dinitrate, and ivabradine
D) Valsartan, verapamil, spironolactone, and empagliflozin
' Correct Answer: A
Rationale: The four pillars of HFrEF therapy are ARNI (sacubitril/valsartan), evidence-based beta-blocker
(carvedilol, metoprolol succinate, bisoprolol), mineralocorticoid antagonist, and SGLT2 inhibitor. Metoprolol
tartrate is not evidence-based for mortality reduction, and verapamil is contraindicated in HFrEF.
Hydralazine/isosorbide is for ACE/ARB intolerance, not a primary pillar.
15. A patient presents with acute unilateral facial paralysis, inability to close the eye, and loss of taste on the anterior
tongue. Which finding would most suggest an alternative diagnosis to Bell's palsy?
A) Postauricular pain preceding weakness
B) Involvement of only the forehead and eye closure
C) Weakness isolated to the lower face with forehead sparing
D) Hyperacusis on the affected side
' Correct Answer: C
Rationale: Bell's palsy is a peripheral (lower motor neuron) lesion affecting both upper and lower face, including
forehead. Forehead sparing indicates an upper motor neuron lesion (e.g., stroke), requiring urgent neuroimaging.
Postauricular pain and hyperacusis are common in Bell's palsy, and isolated forehead/eye involvement is not a
typical stroke pattern.
