Sample DWC Practice Questions

Try these sample questions to test your DWC exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 146+ question experience with AI tutoring.

1Which statement best summarizes the pathogenesis of diabetic peripheral neuropathy?

A.Hyperglycemia drives interacting metabolic, oxidative, and microvascular nerve injury

B.Excess insulin chronically overstimulates Schwann-cell growth receptors

C.Autoimmunity selectively destroys peripheral myelin in typical diabetes

D.High HDL concentrations interrupt distal axonal transport in the feet

Explanation: Diabetic peripheral neuropathy is multifactorial. Chronic hyperglycemia contributes to polyol-pathway flux, advanced glycation, oxidative stress, inflammation, and microvascular dysfunction that injure axons and supporting cells.

2Which feature distinguishes weight-bearing plantar skin from thin dorsal foot skin?

A.It lacks an epidermis over pressure-bearing areas

B.It has a thick stratum corneum adapted to friction and pressure

C.It is lined by mucosa instead of keratinized epithelium

D.It contains hair follicles at every plantar pressure point

Explanation: Plantar skin is glabrous and has a relatively thick epidermis and stratum corneum that help tolerate weight-bearing friction and pressure. Its fibrous attachments also limit skin movement over the underlying plantar surface.

3Which articulations form the Lisfranc, or tarsometatarsal, joint complex?

A.The talus with the tibia and fibula

B.The metatarsal bases with the cuneiforms and cuboid

C.The calcaneus with the talus only

D.The proximal phalanges with the metatarsal heads

Explanation: The Lisfranc complex consists of the tarsometatarsal articulations between the metatarsal bases and the distal tarsal row: the three cuneiforms and the cuboid. This region is a common site of Charcot midfoot disruption.

4Which diabetes-associated process can directly reduce oxygen delivery at a wound edge?

A.Retinal microaneurysms reducing visual acuity

B.Proteinuria from diabetic glomerular injury

C.Microvascular dysfunction impairing capillary exchange

D.Autonomic denervation reducing plantar sweating with dry skin

Explanation: Microvascular dysfunction can impair capillary recruitment and oxygen exchange at healing tissue. In the diabetic foot, however, macrovascular peripheral artery disease must also be sought because it is a major, treatable cause of limb ischemia.

5The dorsalis pedis artery is the continuation of which artery across the ankle?

A.Posterior tibial artery

B.Anterior tibial artery

C.Fibular or peroneal artery

D.Popliteal artery

Explanation: After crossing the ankle, the anterior tibial artery continues onto the dorsum of the foot as the dorsalis pedis artery. Its course is clinically relevant when locating a pedal pulse or Doppler signal.

6A patient cannot perceive a 10-g monofilament at recommended plantar test sites. What does this support?

A.An isolated mild proprioceptive deficit

B.Loss of protective sensation in the foot

C.Severe limb ischemia requiring revascularization

D.A normal age-related finding with no ulcer risk

Explanation: Failure to perceive a correctly applied 10-g monofilament at recommended sites supports loss of protective sensation and increased ulcer risk. Monofilament testing does not assess perfusion.

7What occurs during the windlass mechanism as the great toe dorsiflexes during push-off?

A.The Achilles tendon detaches from the calcaneus

B.The plantar aponeurosis relaxes and the arch flattens

C.The plantar aponeurosis tightens and helps elevate the arch

D.The subtalar joint becomes the only weight-bearing articulation

Explanation: Great-toe dorsiflexion winds the plantar aponeurosis around the metatarsal head. This tightens the fascia, helps elevate the longitudinal arch, and stiffens the foot for propulsion.

8Bilateral absent Achilles reflexes in an older adult with diabetes should be interpreted how?

A.They prove a central lesion at the L4 level

B.They support peripheral neuropathy when concordant with other findings

C.They establish occlusion of the anterior tibial artery

D.They localize an isolated lesion to the tarsal tunnel

Explanation: The Achilles reflex depends on the S1 reflex arc and peripheral nerve integrity. Bilateral absence may support large-fiber polyneuropathy, but age and other neurologic conditions can also reduce the reflex, so it should be integrated with sensory findings.

9Where does the Achilles tendon insert?

A.The neck of the talus

B.The posterior calcaneal tuberosity

C.The navicular tuberosity

D.The base of the fifth metatarsal

Explanation: The Achilles tendon, formed principally by the gastrocnemius and soleus tendons, inserts on the posterior calcaneal tuberosity and transmits plantarflexion force.

10Which motion at the first metatarsophalangeal joint is needed for normal late-stance push-off?

A.Great-toe dorsiflexion or extension

B.Fixed plantarflexion of the great toe

C.Isolated inversion of the calcaneus

D.Locked flexion of the interphalangeal joint

Explanation: Adequate first metatarsophalangeal dorsiflexion permits the body to progress over the forefoot and activates the windlass mechanism during terminal stance. Restriction can alter loading and increase focal plantar stress.

DWC Study Tips from Top Performers

1Master the 10-g monofilament and 128-Hz tuning fork technique and clinical interpretation

2Interpret ABI, toe pressure/TBI, Doppler waveforms, and TcPO2 together; avoid treating one cutoff as a standalone healing guarantee

3Memorize Wagner 0–5 and University of Texas Grade/Stage classification systems

4Understand IWGDF/IDSA infection severity Grades 1–4 and how severity, tissue depth, perfusion, and systemic findings guide management

5Scope the offloading hierarchy correctly: a non-removable knee-high device is first choice for a neuropathic plantar forefoot or midfoot ulcer when not contraindicated

6Use MRSA and anti-pseudomonal coverage only when the patient's risk factors, prior cultures, geography, and infection severity support it

7Review individualized glycemic management, including the ADA perioperative target of 100–180 mg/dL

8Understand Charcot neuroarthropathy diagnosis, offloading endpoints, and Lisfranc involvement

9Assess nutrition individually; do not use a universal protein dose or albumin/prealbumin alone to diagnose malnutrition

10Review interprofessional team roles and IWGDF surveillance intervals by risk category
