Mixed Deck — All DPM Topics Flashcards

A patient on warfarin for DVT develops a foot infection requiring antibiotics. Which antibiotic class is MOST likely to significantly increase warfarin's INR?

Answer: Fluoroquinolones

Fluoroquinolones inhibit CYP1A2 and reduce vitamin K-producing gut flora, significantly potentiating warfarin's anticoagulant effect.

Which imaging modality is the first-line study for evaluating peripheral arterial occlusive disease?

Answer: Duplex ultrasound

Duplex ultrasound (B-mode imaging with Doppler flow analysis) is the first-line non-invasive test for evaluating the site and severity of peripheral arterial disease.

Which of the following is a common side effect of opioid analgesics?

Answer: Constipation

Constipation is a very common and often debilitating side effect of opioid analgesics. Opioids bind to receptors in the gastrointestinal tract, which slows down gut motility and increases water absorption. This leads to hardened stools and difficulty with bowel movements, frequently requiring proactive management strategies.

What documentation practice is considered essential in Surgical Interventions & Procedures within the Doctor of Podiatric Medicine field?

Answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible

Real-time or near-real-time documentation in Surgical Interventions & Procedures ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

What is the primary concern when treating plantar fasciitis with corticosteroid injection?

Answer: Plantar fascia rupture and fat pad atrophy

Repeated corticosteroid injections into the plantar fascia risk plantar fascia rupture and fat pad atrophy, leading to chronic heel pain.

What documentation practice is considered essential in Orthotic Device Prescription within the Doctor of Podiatric Medicine field?

Answer: Recording actions, observations, and outcomes in real-time or as close to the event as possible

Real-time or near-real-time documentation in Orthotic Device Prescription ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

What is the PRIMARY purpose of continuing education requirements in Diabetic Foot Care & Management for DPM professionals?

Answer: Maintaining current knowledge and competency as the field evolves

Continuing education in Diabetic Foot Care & Management ensures professionals maintain current knowledge and skills as standards, technologies, and best practices evolve in the Doctor of Podiatric Medicine field.

A panmetatarsal head resection is most commonly indicated in which patient population?

Answer: Rheumatoid arthritis patients with severe forefoot deformity and multiple plantar ulcerations

Panmetatarsal head resection is a forefoot salvage procedure commonly performed in rheumatoid arthritis patients who have severe, irreducible lesser toe deformities with multiple plantar metatarsal head ulcerations.

In Foot & Ankle Anatomy, what is the FIRST step a DPM professional should take when encountering a new case or situation?

Answer: Conduct a comprehensive assessment and gather all relevant information

In Foot & Ankle Anatomy, a thorough initial assessment ensures all relevant factors are identified before deciding on an appropriate course of action. This systematic approach is fundamental to Doctor of Podiatric Medicine practice.

How does risk management apply to daily practice in Dermatological Conditions of the Foot for Doctor of Podiatric Medicine professionals?

Answer: Through proactive identification of potential hazards and implementation of preventive measures

Effective risk management in Dermatological Conditions of the Foot requires proactive hazard identification and preventive measures, not just reactive responses. This approach reduces incidents, improves outcomes, and protects both professionals and clients.

A patient presents with a well-demarcated, erythematous plaque with silvery scales on the heel. Nail pitting is also noted. What is the most likely diagnosis?

Answer: Psoriasis

Psoriasis on the foot typically presents as well-demarcated erythematous plaques with silvery scales, and nail pitting is a classic associated finding.

Which muscle is the primary plantarflexor of the foot and is innervated by the tibial nerve?

Answer: Gastrocnemius

The gastrocnemius is the primary plantarflexor, crossing both the knee and ankle, and is innervated by the tibial nerve (S1-S2).

In peripheral arterial disease, which lifestyle modification has the strongest evidence for improving walking distance?

Answer: Supervised aerobic exercise therapy

Supervised exercise rehabilitation is the most effective non-surgical intervention to increase pain-free walking distance in PAD patients.

Metatarsus adductus is best described as:

Answer: Medial deviation of the forefoot relative to the hindfoot

Metatarsus adductus involves medial (inward) deviation of the forefoot relative to the hindfoot, giving the foot a C-shaped or kidney-bean appearance.

Which phase of gait is most associated with maximum ankle dorsiflexion?

Answer: Midstance

During the midstance phase of gait, the body's center of gravity passes directly over the supporting foot. As the tibia continues to advance forward over the stationary foot, the ankle joint reaches its maximum degree of dorsiflexion. This allows for smooth forward progression and prepares the foot for the subsequent push-off phase.

A podiatrist treating a patient with rheumatoid arthritis notices foot joint involvement. The patient is on a TNF-alpha inhibitor. Which infection risk must be screened before initiating this therapy?

Answer: Latent tuberculosis

TNF-alpha is critical for granuloma maintenance; its inhibition can reactivate latent TB, so tuberculin skin testing or IGRA is required before initiation.

A patient with gout is started on allopurinol. Which mechanism best describes how this drug reduces uric acid levels?

Answer: Inhibits xanthine oxidase

Allopurinol is a xanthine oxidase inhibitor that reduces conversion of hypoxanthine and xanthine to uric acid.

What is the mechanism of action of hydroxychloroquine when used off-label for inflammatory arthritis affecting the feet?

Answer: Accumulates in lysosomes and raises intracellular pH, impairing antigen processing

Hydroxychloroquine is a weak base that accumulates in lysosomes, raising pH and interfering with antigen processing and TLR signaling.

Which standard of practice is MOST important for ensuring quality in Diabetic Foot Care & Management?

Answer: Following evidence-based protocols while adapting to specific circumstances

Evidence-based protocols provide a foundation of proven practices, but effective Doctor of Podiatric Medicine professionals must also adapt their approach based on specific circumstances and individual case needs within Diabetic Foot Care & Management.

During an ankle arthroscopy, the anterolateral portal is created just lateral to which tendon?

Answer: Peroneus tertius or extensor digitorum longus to the 4th toe

The anterolateral ankle arthroscopy portal is established just lateral to the peroneus tertius or the 4th toe slip of extensor digitorum longus to avoid the intermediate dorsal cutaneous branch of the superficial peroneal nerve.
