Examination with Practice Questions And
Correct An
1. A patient with a history of recurrent lateral ankle instability undergoes dynamic
ultrasound. Which finding best distinguishes functional instability from mechanical
instability?
A. Increased anterior talofibular ligament thickness
B. Excessive anterior translation of the talus during stress
C. Normal ligamentous appearance with impaired proprioceptive response
D. Presence of an osteochondral lesion of the talus
Answer: C. Normal ligamentous appearance with impaired proprioceptive response
Rationale: Functional instability is characterized by proprioceptive deficits and
neuromuscular control issues despite normal ligament integrity, whereas mechanical
instability involves structural laxity. Ultrasound showing normal ligaments with impaired
proprioception points to functional instability. Options A, B, and D describe structural or
mechanical abnormalities.
2. Which of the following best explains why a first-generation cephalosporin is
preferred over a macrolide for prophylaxis in clean podiatric surgery?
A. Broader gram-negative coverage
B. Better penetration into bone tissue
C. Optimal coverage of Staphylococcus aureus and Streptococcus species
D. Lower risk of Clostridioides difficile infection
Answer: C. Optimal coverage of Staphylococcus aureus and Streptococcus species
Rationale: First-generation cephalosporins provide excellent coverage against the most
common surgical site pathogens, Staphylococcus aureus and Streptococcus species.
Macrolides have weaker staphylococcal activity and are not first-line for surgical
prophylaxis. Options A, B, and D are incorrect because cephalosporins do not offer
broader gram-negative coverage, bone penetration is not the primary reason, and C.
difficile risk is not lower than macrolides.

,3. A patient presents with a painful, erythematous, and swollen great toe. Aspiration
reveals needle-shaped, negatively birefringent crystals. Which additional finding is
most consistent with a definitive diagnosis of gout?
A. Serum uric acid level of 5.2 mg/dL
B. Presence of rheumatoid factor
C. Elevated C-reactive protein
D. Positive response to colchicine within 24 hours
Answer: A. Serum uric acid level of 5.2 mg/dL
Rationale: Although serum uric acid can be normal during an acute gout flare, the
presence of negatively birefringent needle-shaped crystals is diagnostic. A normal uric acid
level does not exclude gout. Rheumatoid factor is not specific, CRP is nonspecific, and
response to colchicine is supportive but not definitive.
4. In a patient with diabetic neuropathy, which of the following is the most sensitive
test for detecting early loss of protective sensation?
A. Vibration perception threshold using a 128-Hz tuning fork
B. Monofilament testing with a 10-g Semmes-Weinstein monofilament
C. Superficial pain response to pinprick
D. Ankle reflex assessment
Answer: B. Monofilament testing with a 10-g Semmes-Weinstein monofilament
Rationale: The 10-g Semmes-Weinstein monofilament is the gold standard for identifying
loss of protective sensation and predicting ulcer risk. Vibration testing is useful but less
specific for protective sensation. Pinprick and ankle reflexes assess different modalities and
are less sensitive for this purpose.

,5. A patient undergoes a modified Lapidus procedure for hallux valgus. Which
biomechanical principle is most critical to ensure long-term correction?
A. Restoration of the first metatarsophalangeal joint congruency
B. Fusion of the first tarsometatarsal joint in optimal position
C. Release of the adductor hallucis tendon
D. Lateral capsular release of the first MTP joint
Answer: B. Fusion of the first tarsometatarsal joint in optimal position
Rationale: The Lapidus procedure addresses hypermobility of the first tarsometatarsal
joint by fusion, which is essential for durable correction of hallux valgus. While other steps
may be adjunctive, fusion in optimal position is the key to preventing recurrence. Options
A, C, and D are components but not the defining principle.
6. Which of the following best describes the mechanism of action of duloxetine in
treating chronic musculoskeletal pain?
A. Selective serotonin reuptake inhibition
B. Serotonin-norepinephrine reuptake inhibition
C. GABA receptor agonism
D. Opioid receptor agonism
Answer: B. Serotonin-norepinephrine reuptake inhibition
Rationale: Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) that
modulates descending pain pathways. It is not a selective SSRI, GABA agonist, or opioid
agonist. This mechanism underlies its efficacy in neuropathic and chronic musculoskeletal
pain.

, 7. A patient with a suspected Achilles tendon rupture undergoes the Thompson test.
Which finding confirms the diagnosis?
A. Plantar flexion of the foot upon calf squeeze
B. Absence of plantar flexion upon calf squeeze
C. Pain localized to the tendon upon palpation
D. Positive gap sign at the rupture site
Answer: B. Absence of plantar flexion upon calf squeeze
Rationale: The Thompson test is positive when squeezing the calf fails to produce plantar
flexion, indicating a complete Achilles tendon rupture. Presence of plantar flexion (A) rules
out rupture. Pain (C) and gap sign (D) are supportive but not definitive.
8. Under California law, which of the following is required for a podiatrist to perform
ankle surgery?
A. Completion of an accredited podiatric residency including ankle surgery
B. Certification by the American Board of Podiatric Surgery
C. Additional fellowship training in foot and ankle surgery
D. Approval by the California Podiatric Medical Board
Answer: A. Completion of an accredited podiatric residency including ankle surgery
Rationale: California Business and Professions Code section 2472 allows podiatrists to
perform ankle surgery if they have completed a residency program that includes ankle
surgery. Board certification or fellowship is not mandated. Board approval is not a
prerequisite for licensure.
