This is the correct answer because peripheral neuropathy affects the sensory nerves, which can cause loss of sensation, especially in the distal parts of the body. Diabetes mellitus is a common cause of peripheral neuropathy.
This is incorrect because peripheral neuropathy does not affect the motor nerves, which control muscle tone and reflexes. Increased muscle tone and reflexes in the upper limbs are more likely to indicate a central nervous system disorder, such as a stroke or spinal cord injury.
This is incorrect because peripheral neuropathy can cause decreased pain perception in any part of the body, not just the hands and fingers. However, this is not a specific finding for peripheral neuropathy, as other conditions can also impair pain perception, such as spinal cord injury or opioid use.
This is incorrect because peripheral neuropathy does not affect the autonomic nerves, which control sweating and flushing. Increased sweating and flushing in the face and neck are more likely to indicate a sympathetic nervous system disorder, such as pheochromocytoma or carcinoid syndrome.
Choice A reason:
This is the correct answer because peripheral neuropathy affects the sensory nerves, which can cause loss of sensation, especially in the distal parts of the body. Diabetes mellitus is a common cause of peripheral neuropathy.
Choice B reason:
This is incorrect because peripheral neuropathy does not affect the motor nerves, which control muscle tone and reflexes. Increased muscle tone and reflexes in the upper limbs are more likely to indicate a central nervous system disorder, such as a stroke or spinal cord injury.
Choice C reason:
This is incorrect because peripheral neuropathy can cause decreased pain perception in any part of the body, not just the hands and fingers. However, this is not a specific finding for peripheral neuropathy, as other conditions can also impair pain perception, such as spinal cord injury or opioid use.
Choice D reason:
This is incorrect because peripheral neuropathy does not affect the autonomic nerves, which control sweating and flushing. Increased sweating and flushing in the face and neck are more likely to indicate a sympathetic nervous system disorder, such as pheochromocytoma or carcinoid syndrome.
