Neuropathy Neuropathy Complications and Prevention 1 — Questions and Answers
Question 1: Which preventive foot care measure most effectively reduces amputation risk in patients with diabetic neuropathy?
- Daily application of antifungal cream
- Daily foot inspection and protective footwear (Correct answer)
- Soaking feet in warm water nightly
- Applying emollient creams between the toes
Correct answer: Daily foot inspection and protective footwear
Daily foot self-inspection combined with properly fitted protective footwear significantly reduces ulceration and amputation rates in diabetic neuropathy.
Question 2: Neuropathic pain that is refractory to first and second-line pharmacological treatments may benefit from which interventional procedure?
- Peripheral nerve biopsy
- Spinal cord stimulation (SCS) (Correct answer)
- Epidural steroid injection
- Lumbar sympathetic block
Correct answer: Spinal cord stimulation (SCS)
Spinal cord stimulation is an evidence-based neuromodulation approach for refractory neuropathic pain, particularly in painful diabetic neuropathy.
Question 3: Fall prevention is critical in neuropathy patients because sensory and proprioceptive loss creates which primary hazard?
- Increased cognitive impairment
- Impaired postural stability and increased fall risk (Correct answer)
- Cardiovascular instability during exertion
- Progressive muscle atrophy only
Correct answer: Impaired postural stability and increased fall risk
Loss of proprioception and sensory feedback impairs balance and postural reflexes, making neuropathy patients highly prone to falls and fractures.
Question 4: Which complication of autonomic neuropathy is a recognized cause of silent myocardial infarction in diabetic patients?
- Orthostatic hypotension masking chest pain
- Cardiac denervation eliminating anginal pain perception (Correct answer)
- Resting tachycardia increasing oxygen demand
- Hypertensive crisis from sympathetic overactivity
Correct answer: Cardiac denervation eliminating anginal pain perception
Cardiac autonomic neuropathy causes denervation of the heart, eliminating the pain signals that would normally signal a heart attack.
Question 5: Which non-pharmacological intervention has evidence for improving neuropathic pain and function in peripheral neuropathy patients?
- Strict bed rest
- Aerobic exercise training (Correct answer)
- High-protein dietary supplementation
- Transcranial magnetic stimulation
Correct answer: Aerobic exercise training
Regular aerobic exercise has evidence for reducing neuropathic pain, improving nerve fiber density, and enhancing functional capacity in peripheral neuropathy.
Question 6: Pressure ulcers in neuropathy patients most commonly develop over which anatomical sites?
- Anterior tibial region
- Plantar aspect of the foot over bony prominences (Correct answer)
- Dorsum of the foot
- Lateral ankle
Correct answer: Plantar aspect of the foot over bony prominences
Neuropathic ulcers form over pressure points on the plantar foot (metatarsal heads, heel) where repetitive pressure goes unfelt due to sensory loss.
