MNT Diabetic Foot & Nail Care 2 — Questions and Answers
Question 1: What vascular assessment signs should a medical nail technician monitor in diabetic patients?
- Skin color changes, temperature differences, absent or weak pedal pulses, and slow capillary refill time (Correct answer)
- Only blood pressure readings
- Hair growth patterns on the toes
- Whether the patient can wiggle their toes
Correct answer: Skin color changes, temperature differences, absent or weak pedal pulses, and slow capillary refill time
Poor peripheral circulation manifests as pale or cyanotic skin, cool extremities, thin shiny skin, hair loss on lower legs, weak or absent foot pulses, and delayed capillary refill—all signs requiring documentation and referral.
Question 2: What is peripheral neuropathy and how does it affect nail care?
- Nerve damage that reduces sensation in extremities, meaning patients cannot feel pain from improper nail care or developing infections (Correct answer)
- A type of nail fungus
- Increased sensitivity in the feet
- A condition that makes nails grow faster
Correct answer: Nerve damage that reduces sensation in extremities, meaning patients cannot feel pain from improper nail care or developing infections
Peripheral neuropathy damages sensory nerves in the feet, so patients cannot feel cuts, burns, pressure injuries, or infections. This makes gentle, careful nail care techniques and thorough foot inspections essential.
Question 3: What footwear advice should be provided to diabetic patients?
- Wear properly fitted, supportive shoes that protect the feet without creating pressure points (Correct answer)
- Go barefoot as much as possible to let feet breathe
- Wear tight shoes to support the arch
- Any shoe style is acceptable for diabetic patients
Correct answer: Wear properly fitted, supportive shoes that protect the feet without creating pressure points
Diabetic patients should wear well-fitted shoes with adequate depth and width, avoid walking barefoot, inspect shoes for foreign objects before wearing, and may need custom orthotics or diabetic shoes.
Question 4: What is the A1C test and why does it matter for diabetic foot care?
- A blood test measuring average blood sugar over 2-3 months; higher levels indicate poorer diabetes control and greater risk of foot complications (Correct answer)
- A vitamin deficiency test
- A test for foot infections
- A nail hardness measurement
Correct answer: A blood test measuring average blood sugar over 2-3 months; higher levels indicate poorer diabetes control and greater risk of foot complications
Hemoglobin A1C reflects average blood glucose levels over 2-3 months. Higher A1C values correlate with increased risk of neuropathy, vascular disease, and impaired wound healing, all of which affect foot and nail care.
Question 5: When should a medical nail technician refuse to perform a procedure on a diabetic patient?
- When there are signs of active infection, open wounds near the treatment area, or when the procedure exceeds their scope of practice (Correct answer)
- Never; all nail care is appropriate for all patients
- Only when the patient requests cancellation
- Only when the physician is unavailable by phone
Correct answer: When there are signs of active infection, open wounds near the treatment area, or when the procedure exceeds their scope of practice
Procedures should be deferred when active infection, open wounds, or acute Charcot symptoms are present, when the patient's condition has changed significantly, or when the planned procedure exceeds the technician's training and scope.
Question 6: What documentation is required for diabetic nail care appointments?
- Patient history, current medications, foot assessment findings, procedures performed, and any referrals made (Correct answer)
- No documentation is needed for routine nail care
- Only the procedures performed
- Only abnormal findings
Correct answer: Patient history, current medications, foot assessment findings, procedures performed, and any referrals made
Thorough documentation for diabetic patients includes medical history review, current diabetes management, detailed foot and nail assessment, any abnormalities noted, procedures performed, products used, and referrals made.
