If a patient has an absent knee reflex on their right leg, what could this symptom potentially indicate?

A: It's a sign of an upper motor neuron lesion affecting the right leg, possibly due to stroke on the left side of the brain.

B: An absent right knee reflex may suggest a lower motor neuron lesion, such as discal herniation at level C2-4.

C: An absent right knee reflex may suggest a lower motor neuron lesion, such as discal herniation at level L2-4.

D: An absent right knee reflex points to a traumatic injury of the tibial nerve.

Correct answer is C) An absent knee reflex on the right leg may suggest a lower motor neuron lesion, which could be due to conditions like discal herniation at level L2-4. While an upper motor neuron lesion like a stroke on the left side of the brain can lead to motor symptoms, an absent knee reflex is not a typical sign of such lesions. A traumatic injury to the tibial nerve would not impact the knee reflex.
