Certified Wound Ostomy Nurse (CWON) Practice Test

What areas of the foot should be tested with the Semmes-Weinstein monofilament?

1. Toe pads and acupressure points

2. Middle of the foot and ankle

3. Toe pads and metatarsal heads

4. Heels and plantar arches

The correct answer is: Toe pads and metatarsal heads

The Semmes-Weinstein monofilament test is specifically used to assess sensory perception in areas of the foot that are most susceptible to neuropathy, particularly diabetic neuropathy. Testing the toe pads and metatarsal heads is critical because these areas are commonly involved in the development of foot ulcers due to loss of protective sensation. The toe pads and metatarsal heads experience pressure during activities like standing and walking, making them essential sites for monitoring sensory function and identifying at-risk individuals. This careful selection of areas to test aligns with clinical practices focusing on preventing complications such as foot ulcers in individuals with diabetes or neuropathies, where decreased sensation can lead to unnoticed injuries. Other areas, while they may have relevance in foot assessments, are not the primary focus for the Semmes-Weinstein test aimed at detecting loss of protective sensation.
