  1. A deep tendon reflex graded 4+ with clonus indicates:

    Answer: Upper motor neuron lesion

    Hyperreflexia (4+) with clonus is a sign of an upper motor neuron lesion, as the descending inhibitory pathways are disrupted.

  2. Which dermatome is tested by assessing sensation over the lateral forearm?

    Answer: C6

    The C6 dermatome covers the lateral forearm, thumb, and index finger, commonly affected in C6 radiculopathy.

  3. A patient presents with foot drop on the left side. Which peripheral nerve is most likely damaged?

    Answer: Common peroneal nerve

    The common peroneal nerve innervates the ankle dorsiflexors and evertors; injury at the fibular head is a common cause of foot drop.

  4. During the coordination examination, a patient misses the target when performing the finger-nose test with eyes open. This finding is called:

    Answer: Dysmetria

    Dysmetria refers to the inability to accurately judge distance/target during voluntary movement and is a hallmark of cerebellar dysfunction.

  5. Muscle tone assessed as resistance throughout the full range of motion that is velocity-independent is best described as:

    Answer: Rigidity

    Rigidity is a velocity-independent increase in muscle tone found throughout the range, characteristic of Parkinson's disease (lead-pipe or cogwheel).

  6. Which sensory test involves placing a familiar object in the patient's hand (without vision) and asking them to identify it?

    Answer: Stereognosis

    Stereognosis tests the ability to identify objects by touch alone and depends on intact parietal lobe cortical processing.
