The nurse is performing a neurological assessment on a client with a history of Diabetes.

When testing the ability to feel the vibrations of a tuning fork, the nurse notices that the client is unable to feel vibrations on the great toe or ankle bilaterally, but is able to feel vibrations on both patellae. What should the nurse suspect from these assessments?

Hyperalgesia

Peripheral neuropathy

Hyperparalysis

Lesion of the sensory cortex

Answer and Explanation

The Correct Answer is B

A.   Hyperalgesia refers to increased sensitivity to pain stimuli, not specifically related to the inability to feel vibrations.
B.   Peripheral neuropathy, a common complication of diabetes, often leads to sensory deficits, especially in distal extremities like the toes and feet.
C.   Hyperparalysis is not a recognized term in neurology.
D.   A lesion of the sensory cortex would likely present with broader sensory deficits rather than a specific loss of vibration sensation in the distal lower extremities.
