The CFCN (Certified Foot Care Nurse) exam is administered by WOCNCB and covers 150 multiple-choice questions in 3 hours. The pass rate is approximately 75%. The exam tests four domains: Assessment (25%), Intervention/Treatment (35%), Patient Education (20%), and Professional Practice (20%). Diabetic foot care, wound management, and vascular assessment are heavily tested topics. The certification is valid for 5 years and requires an active RN license with foot care nursing experience.

1Which artery is the primary blood supply to the dorsum of the foot?

A.Posterior tibial artery

B.Dorsalis pedis artery

C.Peroneal artery

D.Popliteal artery

Explanation: The dorsalis pedis artery is the continuation of the anterior tibial artery and serves as the primary blood supply to the dorsum (top) of the foot. It is palpated between the first and second metatarsal bones. The posterior tibial artery supplies the plantar aspect of the foot, while the peroneal artery supplies the lateral lower leg.

2When performing a monofilament test on a diabetic patient's foot, at how many sites should the 10-gram Semmes-Weinstein monofilament be applied?

A.3 sites

B.5 sites

C.10 sites

D.15 sites

Explanation: The 10-gram Semmes-Weinstein monofilament test should be applied at 10 sites on each foot to assess protective sensation. Sites include the plantar aspects of the first, third, and fifth toes; the first, third, and fifth metatarsal heads; the medial and lateral midfoot; the heel; and the dorsum between the first and second toes. Inability to detect the monofilament at any site indicates loss of protective sensation and increased ulcer risk.

3A patient with diabetes presents with a warm, erythematous, edematous foot without an open wound. The foot has bounding pulses and the patient denies trauma. Which condition should the nurse suspect FIRST?

A.Deep vein thrombosis

B.Cellulitis

C.Acute Charcot neuroarthropathy

D.Gout flare

Explanation: Acute Charcot neuroarthropathy (Charcot foot) should be the primary suspicion in a diabetic patient with a warm, swollen, erythematous foot with intact pulses and no wound or trauma history. This inflammatory condition involves progressive bone and joint destruction in patients with peripheral neuropathy. Early recognition is critical to prevent permanent deformity. A skin temperature difference of >2°C compared to the contralateral foot supports the diagnosis.

4Which classification system is MOST commonly used to grade diabetic foot ulcers based on depth and presence of infection or ischemia?

A.Braden Scale

B.Wagner Classification

C.Norton Scale

D.Bates-Jensen Wound Assessment Tool

Explanation: The Wagner Classification system is one of the most commonly used grading systems for diabetic foot ulcers. It ranges from Grade 0 (pre-ulcerative or healed) to Grade 5 (gangrene of the entire foot). The system considers wound depth, presence of osteomyelitis, and extent of gangrene. The Braden and Norton Scales assess pressure injury risk, and the Bates-Jensen Tool is a wound assessment instrument, not a diabetic foot ulcer classification.

5What is the normal ankle-brachial index (ABI) range?

A.0.50–0.70

B.0.71–0.89

C.0.90–1.30

D.1.40–1.60

Explanation: A normal ankle-brachial index (ABI) is 0.90 to 1.30. An ABI below 0.90 indicates peripheral arterial disease (PAD), with values below 0.50 suggesting severe ischemia. An ABI above 1.30 suggests non-compressible calcified vessels, commonly seen in diabetes and chronic kidney disease, and requires further evaluation with toe pressures. The ABI is a critical screening tool in foot care nursing for identifying vascular compromise.

6Which nail condition is characterized by thickened, discolored, and often crumbling nails caused by a fungal infection?

A.Onychocryptosis

B.Onychomycosis

C.Onychogryphosis

D.Onycholysis

Explanation: Onychomycosis is a fungal infection of the nail (most commonly caused by dermatophytes such as Trichophyton rubrum) that results in thickened, discolored (yellow-brown), brittle, and crumbling nails. It is the most common nail disorder, affecting up to 14% of the general population and higher rates in diabetic and elderly patients. Onychocryptosis is an ingrown nail, onychogryphosis is a ram's horn nail, and onycholysis is nail plate separation from the nail bed.

7When debriding a neuropathic diabetic foot ulcer, which debridement method is considered the gold standard?

A.Autolytic debridement

B.Enzymatic debridement

C.Sharp/surgical debridement

D.Mechanical debridement with wet-to-dry dressings

Explanation: Sharp/surgical debridement is considered the gold standard for neuropathic diabetic foot ulcers because it rapidly removes necrotic tissue, reduces bacterial burden, converts a chronic wound to an acute wound, and stimulates healing. It also allows assessment of wound depth and tissue viability. Autolytic and enzymatic debridement are slower alternatives, while wet-to-dry dressings are no longer recommended as they are non-selective and damage healthy tissue.

8Which foot deformity is MOST commonly associated with peripheral neuropathy and involves dorsal subluxation of the metatarsophalangeal joints?

A.Hallux valgus (bunion)

B.Hammer toes

C.Pes planus (flat foot)

D.Plantar fasciitis

Explanation: Hammer toes are the deformity most commonly associated with peripheral neuropathy. Motor neuropathy causes intrinsic muscle atrophy and imbalance, leading to dorsal subluxation of the metatarsophalangeal joints with flexion of the proximal interphalangeal joints. This creates prominent metatarsal heads and increased plantar pressure, significantly raising ulceration risk. Hallux valgus is related to biomechanics and footwear, not primarily neuropathy.

9A patient with peripheral arterial disease has rest pain in the forefoot that is relieved by dangling the leg over the side of the bed. What Fontaine stage does this represent?

A.Stage I – Asymptomatic

B.Stage II – Intermittent claudication

C.Stage III – Rest pain

D.Stage IV – Tissue loss (ulceration or gangrene)

Explanation: Fontaine Stage III is characterized by ischemic rest pain, typically occurring in the forefoot and toes at night when the leg is elevated. Patients often gain relief by dangling the leg over the bed, which uses gravity to improve perfusion. Stage I is asymptomatic, Stage II presents with intermittent claudication during activity, and Stage IV involves tissue necrosis, ulceration, or gangrene. Rest pain indicates critical limb ischemia requiring urgent vascular evaluation.

10Which type of wound dressing is MOST appropriate for a moderately exudative diabetic foot ulcer with healthy granulation tissue?

A.Dry gauze

B.Foam dressing

C.Transparent film

D.Alginate dressing

Explanation: Foam dressings are ideal for moderately exudative wounds with healthy granulation tissue because they absorb moderate to heavy exudate while maintaining a moist wound environment. They provide cushioning, thermal insulation, and do not adhere to the wound bed, minimizing trauma during dressing changes. Dry gauze desiccates the wound, transparent films lack absorptive capacity, and alginate dressings are better suited for heavily exudative wounds.

To be eligible for the CFCN exam, you need an active, unrestricted RN license, clinical experience in foot care nursing, and completion of continuing education hours in foot care as specified by WOCNCB. The exam fee is $395 and the certification is valid for 5 years.

How long should I study for the CFCN exam?

Plan for 60-80 hours of study over 6-10 weeks. Focus on the Intervention/Treatment domain (35% of the exam), followed by Assessment (25%). Complete at least 100 practice questions and aim for 80%+ on practice tests before scheduling your exam.

What is the difference between CFCN and CWCN certification?

CFCN (Certified Foot Care Nurse) specializes specifically in foot care nursing including nail care, diabetic foot assessment, and foot wound management. CWCN (Certified Wound Care Nurse) is a broader wound care certification covering wounds across all body areas. Both are administered by WOCNCB. Many nurses pursue both certifications.
