, 3. A patient with fever, neck stiffness, photophobia, and altered mental status requires immediate
evaluation for:
• Migraine
Meningitis
• Tension headache
• Cluster headache
Answer rationale: The combination is a medical emergency concerning for meningitis.
4. Which principle best describes a useful differential diagnosis?
• List only the most common disease
Include common, dangerous, and treatable alternatives
• Choose the first plausible diagnosis
• Avoid diagnoses that require testing
Answer rationale: A safe differential includes common diagnoses plus cannot-miss and treatable alternatives.
5. A new focal neurologic deficit in an older adult with sudden onset is most concerning for:
• Bell palsy
Ischemic stroke
• Tension headache
• Peripheral neuropathy
Answer rationale: Sudden focal neurologic deficit is a stroke warning sign.
6. Which screening test is primarily used to detect colorectal cancer in average-risk adults?
• PSA
FIT
• TSH
• DEXA
Answer rationale: Fecal immunochemical testing is an accepted colorectal-cancer screening strategy.
7. Which intervention has the strongest broad preventive effect for adults who smoke?
• Vitamin C
Smoking cessation
• Routine antibiotics
• Daily chest radiography
Answer rationale: Smoking cessation substantially reduces cardiovascular, pulmonary, and cancer risk.
8. A patient reports palpitations with syncope during exertion. Which feature is most concerning?
• Symptoms only after caffeine
Exertional syncope
• Occasional skipped beat
• Brief symptoms at rest
Answer rationale: Exertional syncope raises concern for a potentially serious cardiac cause.
9. Which vital-sign pattern is most suggestive of orthostatic hypotension?
• BP rises after standing
A significant BP drop after standing with symptoms
• Pulse remains unchanged and asymptomatic
• Temperature rises after standing
Answer rationale: Orthostatic hypotension is defined by a postural BP fall, typically with symptoms.

, 10. Which test is most appropriate to confirm diabetes in an asymptomatic patient when an initial result is
abnormal?
Repeat an accepted diagnostic test on another day
• Chest x-ray
• Urinalysis only
• ESR
Answer rationale: In an asymptomatic patient, confirmation with repeat testing is generally appropriate.
11. A patient with fever, cough, pleuritic pain, and focal crackles most strongly suggests:
Pneumonia
• Allergic rhinitis
• GERD
• Tension headache
Answer rationale: Fever plus focal lung findings and respiratory symptoms suggests pneumonia.
12. Which symptom is most characteristic of hyperthyroidism?
• Cold intolerance
• Weight gain
Heat intolerance with tremor
• Constipation
Answer rationale: Hyperthyroidism commonly causes heat intolerance, tremor, weight loss, and palpitations.
13. Which symptom is most characteristic of hypothyroidism?
• Heat intolerance
• Diarrhea
Cold intolerance and constipation
• Tachycardia
Answer rationale: Hypothyroidism commonly causes cold intolerance, constipation, fatigue, and weight gain.
14. A patient with polyuria, polydipsia, and weight loss should be evaluated promptly for:
Diabetes mellitus
• Osteoarthritis
• Otitis externa
• Bacterial vaginosis
Answer rationale: These are classic symptoms of hyperglycemia.
15. Which approach is most appropriate when a patient's history conflicts with an initial diagnosis?
• Ignore the history
Reassess the differential and search for discordant findings
• Order every available test
• Assume the patient is incorrect
Answer rationale: Discordant findings should trigger diagnostic reassessment.
16. Which medication history is especially important when evaluating an older adult with dizziness?
• Multivitamin only
Antihypertensives, sedatives, and other fall-risk medications
• Topical moisturizer
• Dental floss
Answer rationale: Medication effects are a common reversible contributor to dizziness and falls.

, 17. Which finding is a red flag in a patient with low back pain?
• Pain after prolonged sitting
• Pain relieved by rest
New urinary retention or saddle anesthesia
• Mild muscle tightness
Answer rationale: Cauda equina features require urgent evaluation.
18. Which is the best initial action when a patient has a potentially life-threatening diagnosis in the
differential?
• Delay treatment until every test is complete
Stabilize and urgently evaluate
• Provide reassurance only
• Schedule routine follow-up
Answer rationale: Life-threatening possibilities require immediate stabilization and evaluation.
19. Which symptom most strongly suggests peripheral vertigo rather than a central cause?
• Vertical nystagmus
• Focal limb weakness
Positional, brief episodes triggered by head movement
• New severe headache with ataxia
Answer rationale: Brief, position-triggered vertigo is characteristic of BPPV.
20. A patient with fever, hypotension, tachycardia, and confusion may be developing:
Sepsis
• Stable angina
• Chronic sinusitis
• Simple tension headache
Answer rationale: The findings suggest systemic infection with organ dysfunction and possible shock.
21. Which preventive counseling topic should be addressed routinely in primary care?
• Only prescription medications
Immunizations, cancer screening, lifestyle, and risk reduction
• Only laboratory testing
• Only acute complaints
Answer rationale: Preventive care includes immunization, screening, and health-behavior counseling.
22. Which history element is particularly important when assessing a new rash?
• Favorite color
New medications and exposures
• Shoe size
• Dominant hand only
Answer rationale: Medication and exposure history can identify drug eruptions and contact dermatitis.
