,Neuropathies
Neuropathy is the abnormal transmission of nerve impulses
causing numbness, tingling, or loss of sensation. Which
pathophysiologic condition is known to lead to neuropathy?
Heart failure
Atrial fibrillation
Pneumonia
Gastroenteritis
Diabetes
*** Diabetes is known to cause diabetic neuropathy due to
the effects of a high blood glucose level on nerves over a
long period of time. Atrial fibrillation, heart failure,
pneumonia, and gastroenteritis are not known to cause
neuropathy.
Which is transmitted by nerve fibers? Select all that apply.
Pain
Motor
movement
Sensation
Temperature
Pressure
*** Nerve fibers transmit pain, sensation, motor movement,
temperature, and pressure.
Etiology of Neuropathy
According to the National Institute of Neurological Disorders
and Stroke (2018), it is estimated that there are at least 20
million people in the United States diagnosed with
neuropathy. There are likely many more people who have
neuropathy but have not tried to seek treatment. Not
everyone who has symptoms is tested, and not
,all tests are able to diagnose all forms of neuropathy. Most
forms of neuropathy are in the peripheral nervous system, so
peripheral neuropathy is a term that is used interchangeably
with neuropathy.

sensory nerves derive from a single spinal nerve root.

cause the symptoms of neuropathy. These include:
